How to avoid trying to connect to a stranger's network with known SSID?

My Laptop knows an access point of my uncle's place. He is using a standard one given by the ISP, e.g. FRITZ!Box 6360 Cable. Alas, at my home there is also an access point with the same SSID. Ubuntu tries to connect to it, which of course is futile.

Is there a way to make Ubuntu understand which SSID it is supposed to be connecting to?

Wireless networks may have the same SSID, but they should not have the same BSSID, so edit the wireless connection and provide the BSSID for the network you do want to autoconnect to.

Run the following command in a terminal. It will list the SSID and BSSID of all wireless networks in range.

nmcli -f ssid,bssid dev wifi

Click on the network manager icon in the top panel -> Edit Connections -> Wireless tab -> select the saved connection by its SSID and click Edit. Fill in the BSSID and click Save. Now it should only autoconnect if both the SSID and BSSID match.
