Ubuntu – How to ban a wifi network in Network Manager


My wifi connection drops sometimes and, for some reason, Network Manager attempts to connect to my neighbor's network, which requires a password that I don't know. The network in question is not listed in the "Edit Connections…" dialog and I can find no reference to it in any configuration file, but still the password dialog pops up every time my main connection drops. Is there a way to blacklist a wireless network so that the Network Manager will never attempt to connect to it? Or, equivalently, how can I remove the configuration data that causes the Network Manager to attempt to connect to this particular network?

Hm... not sure why NeworkManager behave this way. This should only happen if you have already added the wireless network in the list and Connect automatically is checked.... maybe is from a connection configured by another users and made available to all users.

You can try to manually add the wireless network and the uncheck Connect automatically.
