NetworkManager doesn't connect to Wi-Fi after suspend

[Łukasz Konieczny]

After upgrading to Mantic Minotaur, when I suspend and resume the system, NetworkManager doesn't see any Wi-Fi networks and i can't connect to Wi-Fi, unless I log out and log in. I don't know exactly in which package there is a problem, I can only guess, that it is network-manager or plasma-nm. My Wi-Fi adapter is Intel AX201 (Wi-Fi 6), operating under iwlwifi driver. Plasma Network Manager applet doesn't see any connections, unless I log out and log in. Or I can modprobe -r iwlwifi, modprobe iwlwifi. Then I can use nmcli to connect, but graphical interface doesn't work anymore.

This bug can be closed. I know, what caused the problem. It is system76-driver package from System76 PPA, or its dependencies. When I uninstalled it, autoremoved dependencies and installed power-profiles-daemon, Wi-Fi wakes up after suspend.
