If your Mac drops your Wi-Fi connection, it can be the purest nightmare. Without the Internet, you suddenly can’t continue working or even start working.

For most users, a permanent Internet connection is already a matter of course. Even in developing countries thousands of miles away, most businesses, households, and even public places are equipped with modems that enable wireless Internet connection.

Troubleshoot when Mac doesn’t connect to Wi-Fi

Wi-Fi is now ubiquitous and essential for workflows in companies, academia, government agencies, and the media. And thanks to Wi-Fi, we are in better contact with each other than ever before. We use it when we listen to music, write emails and even for shopping.

So if you’ve ever had Wi-Fi connection problems on your Mac, save this article locally so you can read it offline just in case because problems of this kind can have different causes.

1. Check macOS Update

When Mac users update the operating system, the Wi-Fi connection may drop.

After the release of El Capitan, many users had to realize that a Wi-Fi connection was no longer possible – which, to make matters worse, made it difficult to download an update with which Apple wanted to fix precisely this problem. In some cases, users had to set up their smartphone as a personal hotspot to load the patch, which led to further issues such as additional costs.

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

2. Problems with the Wi-Fi signal

To determine if the problem is with the Mac or the Wi-Fi network itself, you can also use an analytics app. Tools such as WiFi Explorer or NetSpot determine the Wi-Fi signal strength for you.

You may find that furniture and walls around you weaken or shield the signal. After looking at the results, you can improve them by placing the wireless router elsewhere or asking your IT administrator to set up a signal booster.

3. Contact your Internet service provider

Put your Internet connection to a speed test. This is possible with various apps, possibly your WLAN router or the provider’s customer portal offers a corresponding function. If nothing else works, a higher speed or switching to another provider could fix some Wi-Fi connection problems.

4. Re-establish the Wi-Fi connection

Sometimes you have to part with old things. This also applies to Wi-Fi connections.

If you’ve already restarted your Mac and router, it’s a good practice to disconnect completely.

For this slightly more complex approach, proceed as follows:

  1. Turn off Wi-Fi.
  2. Open System Preferences.
  3. Select “Network” > “Wi-Fi”.
  4. Click More Options.
  5. Select the network you want to disconnect from, click the minus, and then click OK.

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

5. Clean up your Mac

One of the other factors that can lead to connection problems is a hard drive overcrowded with junk data. Over time, data that isn’t needed can accumulate on Mac, including cache files, email attachments, browser extensions, and even viruses. All of this slows down the Mac and makes it run hot, which can also affect connectivity.
