How Do I Remove External Networks From My Network List?

Has anyone ever found a way to get rid of all those external, neighbors’, wi-fi networks from the network list in the drop down menu? Every now & then, my wi-if will grab a neighbor’s wi-fi instead of my own. There’s at least 20 in that stupid list & only 1 is open.

    First, you can’t get rid of those from your list. Those networks are there and your Mac will show the networks it sees. But the ones you don’t want to use shouldn’t bother you. It is normal to see dozens listed there in a residential area and even more than a hundred in an apartment building. Your Mac should never automatically join one you don’t want it to or ask you to join one.

    Here’s what you need to do. Go to System Preferences, Network. Select Wi-Fi on the left. The make sure Ask To Join Networks is unchecked.

    Next, click the Advanced button. Look through your list of preferred networks. If there is something there that isn’t yours or a place you want to connect to, select it and delete it. If you ever accidentally joined a neighbor’s network it may be listed there and you would automatically join it if it is the strongest network at that moment.

    Thank you Gary – this has helped me to remove all the old modem info from the system.
