Mac keeps disconnecting from wi-fi after Sleep-Wake [How to Fix]

Mac Disconnecting Wi-Fi

When you wake your Mac up from sleep, you might find that it disconnects from the wifi. 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 Wifi details (and password) before proceeding with these steps.

Why does my mac keep disconnecting from wi-fi

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!

  1. Thanks mate, works great.
    Has been driving me mad with very slow re-connection after sleep.
    A large number (10 or more) remembered networks in my list (due to testing other people’s routers).
    Solved my problem. I will watch as number of networks slowly increases again.

  2. Thank you! I’ve hard this issue for the past month and a half and it felt so dumb and infuriating, but I thought it was an outlier and not a known bug. Thanks again

  3. Not working. Have tried about every “fix” found but no help.
    My problem started after initial BigSur update.

  4. If you’ve tried all the fixes and are still facing the issue, there might be a hardware problem. It’s best to contact Apple Support to get professional guidance about it.
