I know, that somethin should be around Wifi adapter, but I am clueless. Sometimes my wifi connection lives long, sometimes is unstable and network should be restarted every 2 minutes

i can see only following pcieport 0000:00:1c.4: AER: device [8086:9d14] error status/mask=00001000/00002000

Seems like kernel issue. Old kernel 5.4.0-52-generic did the same issues to me. I have upgraded my Ubuntu 20.04.1 to kernel 5.6.0-1032-oem and dmesg log is clear for now

sudo apt install linux-headers-oem-20.04 linux-oem-20.04 --fix-missing
