I’ve been experiencing issues lately with wifi on Fedora 32 Workstation. It is installed on my desktop which has an Intel AX200 adapter. I can’t pinpoint what was the exact moment, but maybe a month ago I started noticing significant delays when loading webpages for example. And it only got worse since then. My laptop is working fine (I am using it to write this) on Elementary OS, but it’s connected to the 2.4Ghz frequency as opposed to the 5Ghz on my desktop. However I don’t think that the frequency is the cause here since neither are working on my desktop. It all began as occasional, random increases in loading times, but now I’ve reached the almost unusable levels.
I’ve tried the following:
- installing the firmware from https://www.intel.ca/content/www/ca/en/support/articles/000005511/network-and-i-o/wireless.html
iwconfig <device> freq 5.2G(device is wlp3s0)
/etc/NetworkManager/conf.d/default-wifi-powersave-on.confwith the line
/etc/modprobe.d/iwlwifi.conf with the lineiwlwifi 11n_disable=1`
/etc/modprobe.d/iwlwifi.conf with the lineiwlwifi 11n_disable=8`
journalctl -f, the only significant reports are:
iwlwifi [...]: Queue 3 is stuck 73 190
Microcode SW error detected. Restarting 0x0
lspci’s relevant report is
Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)
Thanks in advance for your help!
