How to see Wi-Fi networks on a Mac

There should be a Wi-Fi icon in the menu bar on your Mac desktop. If you don’t see it, go to the Network section in System Preferences and enable the option Show Wi-Fi Status in Menu Bar. Next, follow these steps to view the Wi-Fi networks on your Mac:

1. Click the Wi-Fi icon in the menu bar.
2. Click Other Networks.
3. In the drop-down menu, you will see the list of all networks available nearby.

To connect to a network, select it, provide the password, and click Join.

If you want to see the list of every network to which you have ever connected, do the following:

1. Open System Preferences and click the Network option.
2. In the Wi-Fi section of the sidebar, click Advanced.
3. View the Preferred Networks list.

Please note that if you want your Mac to forget a Wi-Fi network so that it will not automatically connect to the “wrong” network, you can accomplish this task another way. You can set it up to not automatically join a network to which your Mac had connected before. To do this, in the list of Preferred Networks, uncheck the checkbox in the corresponding column. You can also uncheck the option “Remember networks this computer has joined” and your Mac will not save the data in the Preferred Networks list.

How do you reset network settings on a Mac?

You have two options for resetting network settings on your Mac.

The first way is to find and remove network configuration files manually by following these steps:

1. Turn off your Wi-Fi network.
2. Open Finder and press the Cmd+Shift+G shortcut.
3. In the search field of the window that appears, type /Library/Preferences/SystemConfiguration/ and press Enter.

4. In this location, select and remove the following files:

   • com.apple.airport.preferences.plist
   • com.apple.network.identification.plist or com.apple.network.eapolclient/configuration.plist
   • com.apple.wifi.message-tracer.plist
   • NetworkInterfaces.plist
   • preferences.plist
   
5. Once you remove all these files, empty your Trash.

Don’t worry about the service files because your macOS automatically creates new support files when you turn on Wi-Fi.
