Hi, have you looked into the kernel ring buffer? If it's something related to the kernel or the Wifi AP then you'll see some messages regarding loosing signal, authentication, etc.
So the `dmesg` command should give us more insight into if it's kernel/Wifi problem or just the SW stack Gnome Shell/Network Manager... This is hard to replicate as we don't have your environment and also I run different kernel + DE stack (i3). I have machine with (recent) Gnome shell and the wifi works there ok - both 2.4GHz and 5GHz. I'll check the commits and versions. ---- Petr
