After this upgrade (kernel 5.10.53-1) KDE WiFi drawer shows a yellow ‘!’ and says limited connectivity. However Internet etc works fine. Doesn’t break anything except incorrectly sets the WiFi icon and hover text to say limited connectivity.
From lspci:
00:14.3 Network controller: Intel Corporation Cannon Lake PCH CNVi WiFi (rev 10)
Here is image
Edit/Update: From further down in thread, also “You need to log in to this network” has appeared for me.
From other user findings affects other kernel version and DE (GNOME and KDE confirmed so far).
