If i do not reboot my computer for on average one to two days, my wifi randomly stops working. After looking at the output of dmesg, i figured that it has something to do with the wifi driver.

This is its output: https://pastebin.com/gnd1Etet

This is my device:

can@asuli:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Linuxmint
Description:    Linux Mint 20.2
Release:    20.2
Codename:   uma
can@asuli:~$ uname -a
Linux asuli 5.4.0-65-generic #73-Ubuntu SMP Mon Jan 18 17:25:17 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

How do i fix it?

  • I've had similar behaviour on a realtek chipset which I never managed to get to the bottom of. In the end I pulled the wifi card out and put a replacement (intel) in. Realtek linux drivers can be a bit flaky because realtek themselves don't tend to publish their own Linux drivers. That said... The "usual suspects" here are looking around for an alternative driver for the same chipset eg here and checking other things like ensuring power management is not turning off the device.
