Mac Disconnecting from Wi-Fi after Sleep/Wake [How to Fix]

When you wake your Mac up from sleep, you might find that it disconnects from Wi-fi. Re-joining a network every time you wake up your Mac is one irritating thing. This usually happens when you’ve connected your Mac to other Wifi networks in the past.

Getting rid of this is easy although the solution is a little quirky. You will need the Wi-fi details (and password) before proceeding with these steps.

How to Fix Mac Disconnecting from Wifi after Sleep-Wake

Step #1. Open the Apple menu and then click on System Preferences.

Launch System Preferences on Mac

Step #2. Click on Network.

Click on Network in Mac System Preferences

Step #3. Now, click on the Wi-Fi option on the left → Next up, click the Advanced button.

Click on Wi-Fi then Advanced in Mac Network Settings

Step #4. Click on anything inside the Preferred Networks panel. Then, press Command+A to select all and then hit the minus [-] option beneath the panel to remove all Wi-Fi Networks → Press Okay.

Disconnect All Wi-Fi Networks from Mac

You will return to the Network Panel. Now, let’s add your Wi-fi network back.

Step #5. Click on the Locations pull-down menu and then click on Edit Locations.

Click on Edit Locations in Mac Wi-Fi Settings

Step #6. Hit [+] plus sign to add network location and type in any name → Click on Done.

Add New Wi-Fi Network Location on Mac

Step #7. Press “Apply” and log out of System preferences.

You will be asked to enter the Wi-Fi password once Mac identifies and connects to the WiFi network. That should be it.

By following the above steps, you delete the older data on Wi-Fi networks that your Mac has connected to in the past. Then, you create a new connection which is basically like resetting things. This should solve the disconnect issue.

That’s all, mate!
