Instruction: fix wlan problems of the mac

Most users already take a permanent internet connection for granted. Even in developing countries thousands of miles away, most businesses, homes, and even public places are equipped with modems that allow wireless Internet connection.

Troubleshooting when the Mac does not establish a WLAN connection

WLAN has become ubiquitous and essential to workflows in business, academia, government, and the media. And thanks to WLAN we are in better contact with each other than ever before. We use it when listening to music, writing emails, and even for shopping.

So, if you’ve ever experienced wireless connectivity problems on your Mac, save this article locally so you can read it offline, just in case. Because problems of this kind can have various causes.

1. Check macOS

When Mac users update the operating system, the WLAN connection can drop out.

After the release of El Capitan, numerous users found that no WLAN connection was possible – which, to make matters worse, made it difficult to download an update with which Apple wanted to fix exactly this problem. In some cases, users had to set up their smartphone as a personal hotspot to download the patch, which led to other problems like additional costs.

And with a version of macOS Catalina the same problem occurred again.

A simple solution is to turn the WLAN function off and on again. At the same time, you could also change the name of your home or. change the corporate network and set a new password, which may be. What your IT administrator can do for you. Do this via a cell phone if necessary, and then check to see if the Mac can now connect.

2. Problems with the WLAN signal

To determine if the problem is with the Mac or the WLAN network itself, you can also use an analysis app. Tools like WiFi Explorer or NetSpot will determine the WLAN signal strength for you.

Measuring WLAN signal strength

You may find that furniture and walls in your area are weakening or shielding the signal. After looking at the results, you can improve them by placing the WLAN router in a different location or asking your IT administrator to set up a signal booster.

3. Contact your internet provider

Put your internet connection through a speed test. This is possible with various apps, possibly your WLAN router or the provider’s customer portal also offers a corresponding function. If nothing else works, a higher speed or switching to a different provider might fix some WLAN connection problems.

4. Set up the WLAN connection again

Sometimes you have to get rid of old things. This also applies to WLAN connections.

If you have already restarted your Mac and router, it has proven to be useful to disconnect them completely.

For this slightly more complex approach, proceed as follows:

  1. Disable WLAN.
  2. Open the System Preferences.
  3. Select "Network > "WLAN".
  4. Click on "More options.
  5. Select the network you want to disconnect from, click the minus sign and then click "OK.

Manage WLAN connection on your Mac

Repeat this on any other device experiencing this problem, and then reconnect, enter the password, and then (fingers crossed) there should be Internet access again.

5. Clean up the Mac

One of the other factors that can lead to connectivity problems is a hard drive overflowing with junk data. Over time, data you don’t really need can accumulate on your Mac, including cache files, email attachments, browser extensions, and even viruses. All of the above slows down the Mac and makes it run hot, which can also affect connectivity.

Clean up the desktop with Spotless.

Then clean up macOS using CleanMyMac. This app is a highly effective remedy for a slow Mac. You can use it to get rid of data junk, completely delete apps you no longer use, declutter email folders and attachments, and remove unused plugins. CleanMyMac destroys data junk, clears caches and cleans up drives and hard disks, so that your Mac can unfold its full potential again.
