I recently installed Kubuntu 22.10 on my PC as a dual-boot with Windows 11. It's installed on a completely separate SSD. The motherboard is a Asus ROG Strix X670E-E Gaming Wi-Fi.
Relevant information:
- Ubuntu version: 22.10
- Kernel: 5.19.0-23-generic
- Motherboard Wi-Fi adaptor: Intel Wi-Fi 6E AX210
My Windows 11 install works perfectly as expected after installing the Asus motherboard drivers. However, when I boot into Kubuntu, I'm experiencing an infuriating bug. Initially, the Wi-Fi behaves perfectly. After a random amount of time (so far I've experienced from 4 minutes to 1.5 hours), the PC will stutter for a moment and the Wi-Fi network interface will go down and I'll have no Wi-Fi access. There does not appear to be any specific trigger for this issue and it occurs when I am actively using the PC (including actively using the network connection).
I'm a beginner to Linux so I'm a bit lost as to how to go about debugging and fixing this issue. Here are a few things I've already tried:
- I thought it might have something to do with a power-saving mode issue, so I added this to
etc/modprobe.d/iwlwifi.conf:
options iwlmvm power_scheme=1
options iwlwifi power_save=0
- One post that I found recommended adding this to
etc/NetworkManager/NetworkManager.conf:
match-device=driver:wlp9s0

Would appreciate any possible assistance as it makes working very difficult since I have to reboot to fix the issue and even then, it comes back relatively quickly. Happy to edit my post and add any additional information/command outputs as required for troubleshooting. Thanks in advance!
