NetworkManager frequently refreshes the list of available access points. For some reason this often ends up removing some or all access points only to add them back in a later refresh later. With the exception of the currently connected access point, which is never removed. When all access points of a WirelessNetwork have been removed, it gets destroyed by NMWirelessDeviceItem::_removeAccessPoint(). This however does not happen for the currently connected network due to the always present access point. If this network now happens to consist of multiple access points, the "unused" NMAccessPoints will get removed and added in these refreshes, without the WirelessNetwork getting destroyed. Whenever such an unused access point is added, due to the use of signal tracking this leaks the NMAccessPoint and SignalTracker until the WirelessNetwork is destroyed. However when the NMWirelessDeviceItem is destroyed, for example due to suspending, it stops tracking access point changes, ensuring that the condition for the WirelessNetwork being destroyed can not occur anymore. Even with just two access points, such as can be found in 2.4GHz+5GHz home routers this issue leaks hundreds of NMAccessPoints and SignalTrackers per day. As well as a small number of WirelessNetworks which are also kept alive by the SignalTrackers. To fix this disconnect from the access point when it gets removed and destroy all remaining networks when the NMWirelessDeviceItem is destroyed.

Contributing
To contribute, open merge requests at https://gitlab.gnome.org/GNOME/gnome-shell.
Commit messages should follow the GNOME commit message
guidelines. If a merge request
fixes an existing issue, it is good practice to append the full issue URL
to each commit message. Try to always prefix commit subjects with a relevant
topic, such as panel: or status/network:, and it's always better to write
too much in the commit message body than too little.
Default branch
The default development branch is main. If you still have a local
checkout under the old name, use:
git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
