1. The problem of Mac Not Connecting to WiFi Network could be due to a variety of reasons, ranging from glitches in Modem/Router, over crowded DNS servers to other network connectivity issues. In many cases, the problem of WiFi and Ethernet not working on Mac ends up being due to loose or disconnected cable connections.
2. If your wireless keyboard has stopped working, you may be able to fix it yourself and avoid paying costly repair or service fees. Here are some things you can do to try and remedy the problem.
3. WiFi can be the most convenient way to connect to the Internet, but it’s not occasionally without its difficulties – possibly problems with your Internet Service Provider, the local access point (i.e. Your router or hub), or other technical issues (hardware or software) with the Mac.
4. A good place to start when looking at Wi-Fi problems on your Mac is to diagnose exactly what the issue is. MacOS has a Wi-Fi diagnostic tool built into it that can help.

Now restart your Mac. Now turn the Wi-Fi on; if this doesn’t give you any positive result, you should go for creating a new custom network. Go for the new WiFi network creation with custom DNS. First off, shut down all apps like Safari, Chrome, Mail, etc. That are running on Wi-Fi → Click on Apple menu → Click on System Preferences.

Wi-Fi problems on macOS Big Sur/Mojave/Catalina

Wi-Fi connection — it is central to intelligent life on Earth. But there could be numerous reasons your Mac won’t connect to Wi-Fi: a new software update, broken Wi-Fi preferences, or several networks conflicting with each other. Below we’ll explain what to do when you can’t connect to Wi-Fi or your connection is constantly dropping off.

So here go the most common symptoms for Wi-Fi problems on Mac:

• Mac won’t connect to internet, but other devices will
• Mac connected to Wi-Fi, but no Internet access
• Wi-Fi connection keeps turning off
• Slow or unstable Wi-Fi connection on Mac?

Tip: In case your Mac is generally slow, which obviously affects the Internet too, you may start with fixing the performance issues first. The quickest is to delete junk and old caches from your drive and browsers. Here you can download the free version of CleanMyMac app. It helps to remove the unwanted files, bloatware, and junky web browser extensions. In a few minutes, your Mac should be relatively fresh.

See if your Mac keeps having Wi-Fi connection issues. If it does, read on.

Ways to fix Wi-Fi on Mac

Run the default Wi-Fi assistants

To troubleshoot Wi-Fi problems on Mac it’s good to start with native tools that came with your OS.

Go to Apple Menu -> System Preferences -> Network

This window lets you inspect your Wi-Fi preferences. If your Mac has internet connection problems, click Assist me as shown in the screenshot below. This will launch a built-in Diagnostics tool.

Did it solve the problem? Good news there’s another instrument provided by Apple, a Wireless Diagnostics app.
Option + click the Wi-Fi icon in the top right corner
Click Open Wireless Diagnostics…

Delete and reset Wi-Fi network settings

This step will reconfigure your existing Wi-Fi settings and launch your network experience from scratch. But before you begin, we seriously recommend to back your Mac up using Time Machine.

1. Turn off Wi-Fi and close shut down your browsers
2. Open Finder -> Go -> Go to Folder...
3. Paste in the following line:

4. Select the files listed below (as shown in the screenshot)

preferences.plist
com.apple.eapolclient.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
com.apple.airport.preferences.plist

5. Move these files to Trash (without deleting)
Or move them to a new folder on your Desktop.
6. Restart your Mac
Now you will have to revisit Wi-Fi preferences (Click Open Network Preferences under Wi-Fi icon). Turn Wi-Fi on and select your Wi-Fi network again.

The path above proved to be a good remedy in cases when Wi-Fi connection drops off after upgrading to macOS Catalina. If the issue persists, you may consider to clean install macOS Catalina.

Wi-Fi won't turn on after sleep mode on Mac

In some cases, sleep mode settings is the reason your Wi-Fi drops off on Mac and wouldn’t turn on again. Try this simple fix which many users found helpful:

Go to System Preferences -> Energy Saver
Disable Wake for Wi-Fi network option

Check your Wi-Fi now (cross your fingers). Did it do the trick? If not, let’s move on to the next step.

Flush DNS cache

Another way to fix Mac Wi-Fi not working is to flush your DNS cache. DNS service helps your Mac find IP-addresses, much like in a phone book. It has a cache folder of its own. Removing these cache files is helpful when your Wi-Fi slows down at random or you can’t access certain websites.

To save you from meddling with critical system folders, here’s a quick workaround.

1. Download DNS Flusher (it’s built into CleanMyMac X — get it here).
2. Go to Maintenance tab and tick Flush DNS cache

That’s all — and this solution is 100% free and takes no more than a minute.

By the way, CleanMyMac X is pretty much an indispensable tool if you want to keep your Mac clean and junk-free. It removes up to 74 GB of junk files on an average Mac, so give it a spin, just in case.

Reboot your Wi-Fi router

Macbook Air Internet Not Working

Plug off your router and leave it for a minute or two. This way you will know if your Mac won’t connect to Wi-Fi because of router issues. Plug your router back in and try to connect other Wi-Fi devices in the room.

Additionally, try placing your router in a different place. Your Wi-Fi signal could be lost due to neighboring network or it is catching a “dead-zone” in your house. If your room allows it, move it right in the center of the room. Fewer barriers, the better signal.

Still no Wi-Fi connection on Mac? Switch off the Bluetooth

Wifi Not Working Macbook

Bluetooth devices often interfere with Wi-Fi, especially if the Wi-Fi signal is weak. It’s because both rely on radio frequencies to work. So one more idea to fix your Wi-Fi not working on Mac problem is to inspect the Bluetooth settings.

Try disconnecting the Bluetooth and see if the problem persists.

Go to Apple menu -> System Preferences
Select Bluetooth
Then click Turn Bluetooth off

Update your router firmware

If you are using Apple Airport router you’ll need Airport Utility to perform the update. Obviously, this step requires an internet connection. You can connect via cable if your Wi-Fi doesn’t work on Mac.
Go to Applications
Type Airport Utility in the search bar

You’ll see your Airport base station. If you see a red notification badge next to the base name, click it for more details. If the update is available, the app will show you the Update button.

Customize MTU and DNS settings to fix Wi-Fi on Mac

MTU stands for Maximum Transmission Unit and describes the packet size that is exchanged via the network (measured in bytes). The solution described below implies lowering MTU size which should make your WI-Fi connection less laggy. While customizing DNS location has also proved effective to solve even the most bitter Wi-Fi problems on Mac.

But don’t let these geeky terms put you off. The path takes just about a minute and you’ll be proud to have fixed your Mac Wi-Fi not working, the Apple Genius way.

Step 1.

Macbook Pro Wifi Not Working

Go to System Preferences -> Network
Select Wi-Fi in the left panel
See Location menu on top
Click Edit Locations…

Step 2.
Now create a new location by clicking [+] plus button. Name it anything you like. Click Done.

Step 3.

Then choose your standard Wi-Fi connection under Network Name
Click Advanced
Go to TCP/IP tab and click Renew DHCP lease .

Step 4.

Wifi For Mac Not Working Remotely

Go to DNS tab and by clicking [+] buttons enter 8.8.8.8 and 8.8.4.4 as IP-addresses, each in a separate line. These two are Google’s alternative DNS servers that the company recommends using — they are safe. But before you do this, make sure to copy your current DNS address on a piece of paper.

Step 5.

Go to a Hardware tab from the previous step.
Under Configure dropdown menu select Manually
Click MTU and set the custom size of 1453
Click Apply

Well done. Your Mac Wi-Fi not working should have been resolved.

Still no or poor Wi-FI Connection on Mac?

Maybe all this time you’ve been digging in the wrong place as the problem is in your Mac itself. It might need some basic tidying up and maintenance to run faster. Try giving it a full clean with a tool like CleanMyMac X (it's my favorite among similar Mac tune-up apps — here's the official free download from the developer site). Hopefully, once your Mac is clean and up to speed again, your Wi-Fi should get back to norm.

May the Wi-Fi be with you. Thanks for reading.
