Why your wlan is not working and how to fix it

Why is my WLAN not working?! We all know the frustration that comes with having your wifi connection repeatedly interrupted. Here’s how to fix your wifi connection – whether it’s a router problem, incorrect computer setting, or when your iPhone, Android, Mac, or PC can’t connect to a wifi signal.


If you’re wondering why your internet isn’t working, AVG is here to help with instructions on how to fix your internet connection. And as best we can.

First, save this article!

We would like to help you fix your wireless internet, but since this is an online article, this could be a problem. So if you have a printer, first print it out or at least save this page to your desktop by using Ctrl+S Press. This way, even if your Internet is down, you can still access this article.

Do you have it saved? Good. But before we can start fixing your WLAN, we need to ask you this question:

Why is your WLAN not working?

You can’t cure an infection until you know the cause. Likewise, you can’t fix the wireless until you know why it’s down. Fortunately, there are three possible culprits in such cases: your device, Your Network or the Internet itself.

your device

First, check if your other devices are still connected to the Internet. If so, you know that the problem is limited to just this one device, which will save you some effort. Scroll down further to the section Repairing WLAN access for a device.

Your network

We always advise you not to connect to public networks unprotected, but in this case exceptionally look for a nearby working WLAN, z. B. go to a friend’s house or a nice cafe and test if you can connect online. If this is possible, the problem is rooted in your network and not in the device. Go to the section Fixing problems with WLAN and Internet.

The Internet itself

However, what if your device can connect to your network just fine, but no websites are reachable? First, try opening a wider range of websites to rule out a general internet problem (of course, there’s not much you can do if your favorite website is down due to a DDoS attack). However, if you can’t open any of the websites, go to Fixing Wi-Fi and Internet Problems. You may need to call your internet provider.

Note: If your internet is working but just too slow, there are ways to speed it up.

Some other items to check

Before we go into more complex solutions, let’s try some simpler things first. You may save yourself some headaches by doing this.

Check the lights on your router

Yes, take a look at the box. If something has changed in the indicator lights, this indicates a problem. If you do not know the router well enough to notice any changes, read its user manual. You will find information there about the meaning of the individual lights and how to fix problems.

Reduce the distance to the router

In large houses or places with a lot of interfering signals, it is possible that your wireless connection is not strong enough to reach your device. If a smaller distance helps, there is hope! There are many ways to improve your wireless signal strength.

Connect an Ethernet cable

This does not work with most mobile devices. However, if your affected device has an Ethernet port, connect it to your router using an Ethernet cable (most routers have at least one Ethernet port). If the internet is working, you know that your wireless Signal is responsible for the problem . a good starting point.

Does the problem always exist or is it intermittent?

If your WLAN goes down for no apparent reason and then works again later, it’s probably due to faulty software on your router or device. If this is happening to all of your devices, updating the router’s firmware (also good for your security!) Remedy. If only one device is affected, you may want to update its WLAN driver. In the next paragraph we will take a closer look.

Is your software and hardware up to date?

Finding out if your software or hardware is up to date can be difficult – especially if you can’t use an online connection. For software, the best and easiest way is to install a driver updater that will automatically check your drivers and install available updates. Without an online connection or with outdated hardware, however, you may need to contact an expert to provide the parts you need or install drivers offline.

The same applies to router problems. While it is possible to manually update your router’s firmware (we’ll show you how to do that later in the article), you may still need to contact your provider or an expert to get those firmware updates, or if there’s a problem with your hardware.

Is the WLAN turned on at all?

Yes, this may be a silly question, but sometimes the WLAN is accidentally turned off or airplane mode is activated. Take a quick look to rule out this possibility before you continue pulling your hair out.

Perform a ping test

When you go online, you send many small packets of data to a remote server, which also sends back small packets of data. How your PC communicates with websites. A ping test can be used to check if these tiny packets are reaching their destination – which can be extremely useful in diagnosing the problem. How to perform a ping test

Under Windows 10

Click on the "Start" button and type "Cmd". This should open the Command line and then click on it.

A black area with a blinking cursor will be displayed. Type "ping" and then press the space bar.

You are ready for the test. Continue reading below.


On Mac

Open Spotlight and type "network utility" in the search bar.

Double click on the application Network Utility, to open them.

Search for the tab Ping, click on it and then look for the empty field to enter a web address.

You are ready for the test. Continue reading.

Okay – from here on Windows and Mac users can enter any web address and perform a ping test. However, if you want to diagnose the problem, you should use these three addresses for the test:

Google.comIf this does not work, it means that the DNS system on your device is not working. Read the Fixing WLAN from Devices section of this article This is the IP address of Google’s Public DNS (Domain Name Server). If this doesn’t work, it means that the TCP/IP settings on your computer are not working. For more details, see the Fixing WLAN from Devices section of this article. This is your computer’s own IP address. If this doesn’t work, it means that something is wrong with your network adapter or your connection settings. Read the section Troubleshooting WLAN and Internet Problems.

If you run the test successfully, it will give you a series of letters and numbers that you don’t really need to understand. If it doesn’t work, you’ll get an error message that goes something like this: "Request timed out", "Destination host unreachable or "Transmit failed, error code #". If you see messages like this, you have taken the first step in identifying your problem.

Fix problems with WLAN and Internet

So now it’s time to roll up your sleeves and solve the problem with your router. But many of the solutions we discussed require access to your router and WLAN, so first we need to figure out how that works. Are you ready?

First check the router itself

If you’re lucky, there will be a sticker on the router with its IP address and password, making it easier for you to access its settings. If this label is present, simply enter the IP address noted there into your browser’s address bar and the username and password into the login screen that appears. When logging into the router for the first time, you may be asked to change your username and password. Make sure you don’t forget these: they are very important

But if you can’t find it actually forgotten.

What to do if the username and password of the router are not known?

First, look in the router’s documentation: probably the details are noted somewhere in a manual. But don’t worry if you can’t find any corresponding information or if you have disposed of the documentation long ago! There is a solution.

Open this list of default routers and passwords, find your router model and use the username and password in the list. If you can’t find it: Just try using "admin" as the username and "password" or "password" as the password. Chances are very good that this will work. Ironically, this list is also the reason why it is so important to update your router’s username and password! You don’t even have to be a hacker to find a list of default usernames and passwords on the Internet and play around with other people’s routers.

However. If you or someone else has changed your router’s username and password and you just can’t remember it, there’s still hope. Find the reset button on your router and hold it ca. Pressed for 10 to 20 seconds. This will reset the device to factory defaults and restore default username and password. It is also not impossible that resetting may fix your problem.

Get the IP address of your router

There is no sticker with information? Don’t worry. This will only require one additional step.

For Windows 10 PCs

Click the Windows Start button and type "View network status" (just type it, your computer understands it). This should open the View network status and tasks will be displayed. Click on it.

At the top right you will see your current connection, with some bars to show the signal strength. Click on the link next to it.

A WLAN status box will appear. Click on the button Details.

Some text will be displayed that may confuse you at first. You can ignore it almost completely. The only currently relevant information is IPv4 default gateway. Look for the entry and the numbers next to it. Write them down, including the points!

For Macs

Open Spotlight and look for "System Preferences". Click on System Settings.

Look for the button Network and click on it.

Some connections should now be displayed on the left side. Find the connection you are currently using, make sure it is highlighted and the adjacent indicator is green, and click the button Advanced.

On the tab TCP/IP you will find the section Router , followed by some numbers and dots. Make a note of them, including the points.

Once you have determined the numbers and dots of the router’s IP address, all you have to do is open your browser and enter them into the address line. You will then be taken to the login page of your router.

You don’t know the login data of your router? See the previous section.

You now know how to get into your router. Perfect! Now we can start with the actual troubleshooting.

Have you turned it off and on again?

Technology can be strange. Sometimes a little kick in the butt is all it takes to get things working again. Turn off the power to your router and/or modem, wait five to ten seconds, then turn it back on again. Wait a short while and then check if everything is ok again. If so, that would be great. Glad we could help.

. However, if Continue to there is a problem, and you have to repeat switching on and off to make it work, the problem is more serious. You will probably need to get a new modem and/or router.

Change the channel setting for the WLAN

WLANs are not magic. You use "channels" for wireless communication, with some channels being better than others – especially in environments with many competing devices. Changing the channel of your WLAN could not only fix the WLAN connection, but also make it faster. if you are lucky.

Be sure to log in to your router using the steps above, and then find the page for the WLAN settings. We’d love to help you with this, but every router has a different setup, so you may need to do a little research. Once you find the page, you should see some options for adjusting your wireless signal. Look for the option first Channel: probably this is next to a dropdown menu and has numbers for the GHz range. Pay attention to which channel you are currently using.

Now just try a new channel and save the change. Wait a few minutes and check if anything has changed. Then try it again if necessary. try again with another new channel.

If changing the channel results in an improvement, that’s great! Have fun surfing! If the change does nothing, reset the original channel before trying any other solution. Without this step, you could fix the original WLAN problem without realizing it because the newly set channel won’t work.

Update firmware

The technology works only in the interaction of hardware and software, where the firmware is the place where both mix, it is close to the hardware and software at the same time. But we do not want to split hairs. Many devices automatically update their firmware when they detect that a new update has been released for them. However, routers usually need to be updated manually. This could solve all your connection problems.

First, log in to your router using the method described above. Then find a tab or section called Firmware, Router upgrade, Update or similar. Depending on the router you are using, this will look different. So take a closer look at it if you are a bit uncertain.

On the corresponding page, the firmware version is clearly displayed and there is a button with the label Check, Scan, Update or similar. Click on it and check if there is a more recent firmware: in some cases the update will be downloaded automatically, in others you will have to click on a link and do it manually. Just follow the instructions.

But let’s say you can’t find the firmware page, or there are no corresponding buttons. Don’t despair: identify your router model and then visit the manufacturer’s website. There should be a support page where you can download current firmware and drivers. If not, you really seem to have a rather "modest" router.

You might want to replace it.

Check cables

Check on your router if everything is connected as it should be. If not, fix it and check if everything works now.

With a little luck that’s it.

Check DHCP settings

DHCP (Dynamic Host Configuration Protocol) is a system that quickly and automatically distributes IP addresses throughout the network. IP addresses are important, they are the key for devices to connect and communicate over the internet. If something is wrong with your DHCP, your Internet is not working properly, if at all.

First we need to make sure that it is turned on at all.

In Windows 10

Open the Start menu and type "Settings a. Click on the button Settings.

Click Network and Internet.

If you are using a wireless connection, click the tab on the left Wireless. If you are connected via Ethernet, click on the tab Ethernet.

Your current connection should be displayed. Click on it so that another window opens.

At IP settings the option to IP assignment displayed. If Automatic (DHCP) is displayed, the function is switched on.

If not, click on the button below it Edit and select Automatic (DHCP) from.

Check if internet access has improved.

On Mac

Open Spotlight and search for "System Preferences". Click on System Settings.

Look for the button Network and click on it.

Make sure your network is highlighted and a green dot is displayed next to it. Then click the button Advanced.

Click on the tab TCP/IP.

As the first option should be Configure IPv4 are displayed. If the current setting is not DHCP is displayed, select this from the drop-down menu.

Check if the Internet access has improved.

If that doesn’t work, there’s another option: you can configure DHCP in the router itself. However, this should be considered a last resort before resetting the router to factory defaults (which is described in the next section), unless you know exactly, What you do.

First log in to your router using the steps described above and open the router settings. Every router is set up differently, so you may have to do a little research to get to the settings. In the settings, look for the "DHCP server settings" option. Here you can enable or disable this option and make other settings, such as .

Start IP address: The IP address of your router. Changing it would not do any good, so leave it as it is.

Maximum number of users: Specify how many IP addresses should be handled by DHCP at the same time. If there are really 50 neighbors trying to penetrate your network, you should decrease the value, otherwise the default value can be kept.

IP address range: Bound to the maximum number of users, the range from which DHCP obtains the IP addresses to be distributed is displayed here. If you notice that the possible range is smaller than the maximum number of users, something is wrong: it means that IP addresses might overlap, which will cause problems.

Client Lease Time: Client Lease Time allows you to specify the maximum amount of time a device will receive a specific IP address before it must either be renewed, replaced, or deleted. If you have many Have devices on your network, you may need a shorter lease term so IP addresses aren’t wasted. If you only have a few devices, a longer lease period can help things run better. This may help to fix problematic disconnections.

DHCP reservation: Here you can "reserve" a specific IP address from your IP address range for a specific device. If you decide to do this, you will also need the physical MAC address of your device, which you can find in the Properties find your wireless or ethernet connection.

But again, you should consider this as a last resort.

Reset the router to factory settings

This is something like the ultimate power off and power on, because it will reset your router to the settings it had when it was shipped from the factory. If your router has only recently started causing problems, this might help. However, any changes you made to the router’s settings will be lost.

The procedure is simple. Every router has a reset button, sometimes hidden in a tiny hole on the back that you can only reach with a needle or other pointed object. Find the button and hold it down for ten to twenty seconds. That’s all. Wait for the router to configure itself and see if that fixes the problem.

Try different settings of your network adapter

If you did the ping test mentioned earlier and got an error when you tried to ping your own IP address, this could indicate a network adapter failure. Usually restarting your computer or enabling DHCP (see above) will fix this, but sometimes this is not enough.

Update the driver

Another solution is to update the network adapter driver. On a Mac this is automatic, but on Windows it can be more complicated. Unfortunately, you need access to the Internet. Open the start menu, type "device manager" and click on the button that appears Device manager. Scroll down to the option Network adapter, click on it and then right-click on your adapter. You should see an option to check for updates and install new drivers.

Actually remove it

If you are using a desktop PC, you can open its case and remove the network adapter hardware.

Here’s what a wireless adapter looks like:


A wired adapter looks like this:


The surest way to identify this one is to look at its connectors: a connector where you can screw in an antenna (as in the first example) or plug in an Ethernet cable (as in the second example) is exactly what you’re looking for. If you feel confident, you can turn off your PC completely (not just put it into sleep mode), remove the network adapter, and remove it (z. B. with compressed air). Yes, it must be compressed air (from an aerosol can): with a cloth or a suction cup you could damage the part.

Reassemble the part, turn on your PC and check if it helped. Even if the problem isn’t solved, at least you’ll have a slightly cleaner PC.

This is technically possible on laptops as well, but we would advise against it if you are not a professional. This can also void your warranty on an Apple desktop, so don’t try this on a Mac.

Contact your providers

So good. If none of the above works, it’s probably time to go. You will need to call your provider and ask them for help. We know how inconvenient this is, but what must be, must be.

In addition, if you have taken some of the steps above, you will undoubtedly save yourself further time and headaches by being able to explain to the support staff what has already been tried out. This will make it easier for your counterpart to identify the problem and make useful suggestions.

Repair Wi-Fi access for one device

So the problem is not rooted in your router. This is great. Repairing Wi-Fi access for a single device can be much easier. Sometimes. Grab the problem device and try a tried and true method.

Reset your device

No, I don’t mean closing it and reopening it or putting it into sleep mode. I mean actually turn it off and on again. You’d be surprised how often this fixes not only WLAN problems, but all sorts of other technical issues as well. It’s also dead simple and therefore worth trying before you try anything else.

If that doesn’t help, there are a few tricks you can try to clean and speed up your PC. This is exactly what your PC might need in order to get along with the WLAN properly again.

Reset to factory settings?

If your device was previously able to connect to the Internet, but now it no longer works, can the problem can be fixed by resetting to factory settings, but only for a software-related error. Also, most likely your personal files stored on the device will be lost or their recovery will take a considerable amount of time. So you should only do this if you have backed up all your files and no other action has helped.

The upside: if the problem persists after a factory reset, you know it’s hardware related… and if you’re considering buying a new device, you know your old one can be recycled without hesitation. The silver lining

Under Windows 10

Open the Start menu and type in "Reset".

Click on Reset this PC.

Click in the section Reset this PC on Let’s go.

You have the option to keep your personal files or not. We recommend keeping these for now, but make sure they are backed up anyway.

The reset is started. Make sure your PC is left on, otherwise you may get errors.

On Mac

First make sure that you have created your backups.

Disable your iTunes account, as well as any other third-party app that only allows a limited number of installs, since a freshly reset Mac will register as a new device.

With iTunes, at least, it’s pretty simple: open the app and then click on Account.

Click on Permissions and then click Share this computer.

After entering your credentials, you can get started.

Open your Mac in recovery mode by rebooting and holding down the Command and R keys during the boot process.

Click on Disk Utility and then Continue.

Select the main drive and click on it Unhook and then click on "Delete.

Close the utility and follow the instructions to install the operating system.

For Android

Back up your data (you can easily do this via the cloud).

Tap on the app drawer.

Find the icon Settings and tap on it.

In the left pane, tap Backup and reset.

In the right pane, uncheck the checkboxes Back up my data and Restore automatically. Otherwise, after the factory reset, it may simply restore all your data.

Then tap on the option "Erase all data (factory settings)".

For iOS

Select General.

Switch to Settings. There you will find the option Reset. Tap on it.

Find the option content& Delete settings.

Click on it and then enter your credentials.

Your phone will be cleaned up.

Run network diagnostics

Network diagnostics and troubleshooting have the dubious reputation of being only moderately useful, and not without reason. But they are easy to use, harmless and occasionally help to solve the problem. So it’s worth giving it a try anyway.

On Windows 10

Right-click on the wireless icon in the lower right corner of the screen.

Click on Troubleshoot.

Follow the instructions.

Under Mac

From the Apple menu, click System settings.

Click Wizard and then click the button Diagnosis. This will open the network diagnostics tool.

Click on Continue and follow the instructions.

On a Mac, you can also run a much more detailed diagnostic that might solve your problem.

If you have other components connected to your Mac besides the mouse, keyboard, monitor, power cord, and Ethernet cable, disconnect them.

Turn off your Mac, turn it back on, and press and hold the D key while booting up.

Press and hold until you see a screen asking for the language setting. Choose one, preferably one you understand.

Some tests will be performed for a few minutes. Follow the instructions on the screen.

For Android and iOS

If your Android device or iPhone can’t establish a WLAN connection, there’s bad news: none of the mobile operating systems have built-in network diagnostic tools. However, you can download apps that serve this purpose. Try Network Analyzer on Android and Pingify on iPhone.

Verify WLAN password

It is not impossible that devices forget or store the WLAN password incorrectly, this typically happens as a result of an error. So open your wireless settings and check that everything is still as it should be.

On Android/iOS devices, this is technically possible, but it requires you to either A) root and/or jailbreak your device, which is risky and could void your warranty, or B) download apps that are not available in official stores because they violate terms of service, which is a security risk. That’s why we’ll only show you how to do it on Windows and Mac.

On Windows 10

Click on the Windows Start button and type "Show network status. Click on the option View network status and tasks, which is displayed.

At the top right you will see your current connection, with some bars to show the signal strength. Click on the link next to it.

A WLAN status window should appear as a result. Click on Wireless properties.

Click on the tab Security.

There you will find your security type as well as the password. Click on Show characters and make sure that the password matches your records.

Under Mac

Open Spotlight search and type in "Keychain Access". Click on the app that appears.

At the bottom left, you should see some categories. Make sure that Passwords highlighted, and then double-click your network in the list. You can use the search in the corner to find it if you know the name.

Click at the bottom Show password. You may need to enter the administrator’s username and password.

Check if the password matches your records. If this is not the case, update it and try again.

Reset your TCP/IP settings

If you did the above ping test and couldn’t reach Google’s Public DNS, then this is the step you need to take. It might also be worth doing anyway, as it won’t exactly hurt your PC or Mac.

Under Windows 10

Open the Start menu and search for "cmd".

Right click on Command Prompt and then click Run as administrator.

A black area with a blinking cursor will be displayed. Type "netsh int ip reset" without the quotes and press enter.

Wait a bit until the run is finished, and then restart your PC. Let’s see if this helps.

Under Mac

Click on the Apple icon in the upper right corner and then click on System Settings.

Select Network from.

Find your current network and make sure it is highlighted. Then click on Advanced.

Locate the tab TCP/IP, click on it and then on Extend DHCP lease.

Click on "Ok" and see if that worked.

Remove and add wireless network again

This is similar to rebooting your network: sometimes your device just needs a little push before it can start working properly again. It’s also refreshingly easy to do.

Under Windows

Left-click on the wireless icon in the lower right corner of the screen.

All available wireless networks will be displayed. Right-click on your current connection and click on Discard.

Your connection drops, but if you check the list of available wireless networks, you should still see it there.

Click on it with the left mouse button and press Connect. You may need to enter your credentials again.

See if it works.

Under Mac

Click the wireless icon at the top of the screen and select Open Network Settings from.

Check "WLAN" in the options on the left and then click the button Advanced.

Click the tab WLAN and find your current connection in the "Preferred Network" list.

Click on it and click on the button below. Then click on the button Remove in the following popup window.

Press OK , to exit the menu. Click on Apply and then try to rejoin the network by clicking on the "WLAN" button. You may need to enter your credentials again.

For Android

Tap on the icon Settings.


Locate your current connection, hold it down until new options appear. Click on Ignore network.

Try joining the network again and see if it works. You may need to enter your credentials again.

For iOS

Tap the app Settings.

Tap on WLAN.

Tap the button i (lower case) next to your network.

Click on Ignore this network and then close your settings.

Try joining the network again and see if it works. You may need to enter your credentials again.

Clear your browser cache

The browser cache is a small trove of website data that can help you load pages faster, but can also affect your connection if something goes wrong. Clearing your browser cache is done on a browser-by-browser basis, so find your preferred browser in the list below. By the way, cleaning up your browser also increases security. Even if this doesn’t fix your WLAN, it’s still worth it.

Google Chrome

First open Chrome.

Click on the three dots in the upper right corner.

Click on History and then on the sidebar tap again on History.

A new tab should open. Find links Delete browser data. You can also find it with the three bars above.

Another new tab and a pop-up window will be opened. Change the top menu to Always and make sure that the checkbox next to Cached images and files is enabled.

Click on Clear data and see if that helps.


First, of course, open Firefox.

Click on the menu bar Chronicle.

Click on Delete recent history.

Make sure that the checkbox Cache is activated and the pull-down menu at the top Always indicates.

Click on Delete now and see if that helps.

Microsoft Edge

Open Microsoft Edge.

Click on the three dots to the right of the web address.

Click on History with the clock arrow icon.

Click on Clear History.

Make sure that the option Cached data and files is enabled. Then click on Delete .


Open Opera.

Open the Opera menu at the top left of the screen.

Move the mouse cursor over History and click on Delete browser data.

Click on Cached images and files and then click Clear Data.

See if that helped.

AVG Secure Browser

Open it first.

Click on the three dots at the top right of the screen and then on History.

A new tab will open. Look for the tab Privacy Cleaner and click on it.

A new tab and a pop-up window will open. Change the top menu to Entire period and make sure that the checkbox next to Cached images and files is activated.

Click on Delete browser data and see if that helps.

For mobile devices

Yes, here we are again.


Open the app.

Click on the three dots in the corner.

Tap on Settings and then scroll down to Delete private data.

Make sure that next to the option Cache a check mark is set.


Google Chrome

Tap on the app.

Click on the three dots in the top right corner.

Tap on History, then on Clear browser data. in the new window above.

Change the period to Always.

Make sure that next to the option Cached images and files a check mark is set and then click on Clear data.

See if that helped.

Microsoft Edge

Click on the star in the upper right corner.

Click on the clock icon. It is located in the fourth place from the right.

Click on the recycle bin and confirm that you want to delete your history.

Change the time period to Always and make sure that the checkbox is checked Cached images and files is activated.

Click on Delete and you have done it.


Open the app.

Locate the O menu button at the bottom right and tap on it.

Click on the clock icon, i.e. your History, and then tap the trash icon in the upper right corner. Confirm that you want to delete your browsing history.

This is basically it. See if it helped.

Remove problematic apps and plugins

Sometimes recently installed apps and plugins can be the source of your woes, especially if they hog the Internet or, heaven forbid, it’s malware in disguise. Cleaning up your system might be enough to restore your Internet connection. You can start by uninstalling the apps and plugins that you last installed before you started experiencing problems (we’ll talk about that in a second), or you can try to be more specific and figure out which apps might be causing the problem. Fortunately, there’s an easy way to check which apps might be the problem: our old friend, Task Manager.

For PCs you can open the Task Manager simply by pressing Ctrl + Shift + Esc at the same time. There you will see numerous processes: However, all you need to pay attention to is the category Network on the far right. See about it a really big percentage? If so, scroll down and check what apps are taking up so much of your network. If not, you have another problem.

For Macs the activity display has the same function. You can find them either with Spotlight or in the Utilities folder. Once you have it open, you should be able to click on the tab that says Network Tap above. Check if any devices are taking up a lot of space on your network: If you find any, they represent your problem. Otherwise, this will not help you fix your WLAN.

On Android apps it is a bit more difficult. There is no easy way to tell which apps are currently interfering with your connection. This is why you need help from a third-party app. We recommend GlassWire.

On iOS: First open the Settings and then click Mobile network. Find the section with your apps, for which a number of switches are listed. You should also see how much data they are using. Check if an app is using far more data than is appropriate – there’s a good chance it’s your problem app.

However, it’s not enough to just find out which app is the problem: we also need to remove it. So.

On Windows 10

Open your start menu.

Type "Add". Add or remove programs should be the first option suggested. Click on it.

Here you can see all the programs that you can remove. Find the one you don’t like anymore. Click on it and then click on [Uninstall].

Follow the instructions and see if that helps.

On Mac

Use Spotlight to find the icon or app you no longer need.

Click on it and then drag it to the Trash.

You can also use the keyboard shortcut Mac icon + Backspace.

Right click on the recycle bin and click on Empty the Recycle Bin.

For Android

Put your finger on the app icon.

Drag it up until it appears at the top of the screen.

If you can’t find the problem app on your home screen, go to your Settings.

Scroll down to the bottom and tap on Manage Apps.

Find the problem app and tap on it.

If it’s not absolutely necessary, you should be able to uninstall it.

For iOS

Find the app you don’t like.

Hold your finger on it. Soon it will start to wobble. Wait until all apps start to wiggle as well.

Click on the x that appears in the corner.

Confirm that you want to delete the app.

If you can’t find an icon for it, switch to your Settings.

Go to General and then to iPhone storage.

Select the app that you no longer need and then tap on Delete app .

Even if you can’t find an app that’s causing a lot of problems, your applications may still be collecting remaining files and other junk data that’s slowing down the device in general. Getting rid of everything wouldn’t help the WLAN, but it might help the browser run better.

Update your device and drivers

These are two different things, but they both involve updating. This is why we put them together.

Update drivers

Outdated drivers can cause all kinds of problems for your PC, u. a. Interfering with its ability to detect a wireless signal. but alternatively, a bad update for your driver can sometimes leave it broken until the publisher releases a fix.

Macs, Android and iOS devices update automatically. There is not much you can do about it. However, PCs still need manual updates, which of course require an Internet connection or an expert to provide you with the updates on a USB device.

Using driver update software would be best and easiest (like AVG Driver Updater), but it is quite possible to do it yourself. Open the Start menu, type "Device Manager" and click on the button that appears Device Manager. Here you can see all types of devices for which there are drivers: Some of them might need. updates, but you should focus specifically on Network adapters, Computers, hard disk drives, Bluetooth, proximity- and System devices focus. Anything that might have to do with your WLAN.

What if the updated driver is the problem?

Honestly, if it’s that the current driver update is causing the problem, you probably won’t be able to fix it yourself. Some driver update software (like AVG Driver Updater) has a rollback feature that can undo problematic patches, but for Android, iOS, Mac or manually updated Windows devices, you can just wait until a new patch is released. This should happen quite fast. Check the website or somewhere else to see if a faulty driver could be behind your WLAN problems: If this is the problem, you won’t be the only one suffering.
