I’ve recently upgraded to the 6.11.2 kernel and started experiencing issues with Wi-Fi connections. Wi-Fi has worked fine for over a year now so this is a recent development.
After checking journalctl I believe that this might be an issue with ath10k_pci and a possible driver regression, but I am not entirely sure since I am fairly new to the Linux world.
I think I’ve always received PCI-E errors relating to the Wi-Fi module of my laptop (VivoBook 15_ASUS Laptop X542UF 1.0), but they have been automatically corrected, so no real issues.
Wi-Fi worked for around an hour or two, but then the connection mysteriously dropped. Xfce claimed to be connected even though my hotspot was turned off, and restarting NetworkManager.service did not work and resulted in huge amounts of lag (could not move cursor).
Here is the (slightly trimmed to fit pastebin) journalctl from the boot: https://pastebin.com/BhHwj0pK
And here is my lspci: https://pastebin.com/pixR1Sbf
What are my next steps, is there something wrong on my part or is this a driver / kernel regression that needs to be reported?
