Public bug reported:
I have an HP Omen 15 with AMD Ryzen 7 4800H CPU and GeForce GTX 1660 Ti
discrete graphics card, running kubuntu 20.10 with "Ubuntu
5.8.0-41.46-generic 5.8.18" kernel and nvidia proprietery graphics
drivers. One of my problems (unfortunately there are a lot) is that
every now and then the laptop boots without wifi support. It seems as if
the wireless controller does not even exist.
I have captured the output of dmesg and lspci in the "good" scenario,
i.e. when I do have wifi (which is the most frequent case) and in the
"bad" scenario, i.e. when wifi disappears.
Please note that I haven't found a way to fix this issue after boot, so
I need to reboot the machine in order to get my wifi back, which most of
the times works, but sometimes I need to reboot 2 or 3 times before it
appears again. I haven't found a pattern yet, it seems pretty random.
