Hello friends, I’ve just installed Fedora 35 and I’m dealing with very slow, and also highly variant WiFi speeds with an Intel Wireless-AC 9260. My download speed usually sits around 2 Mpbs, but will go as low as 0.5 Mbps and as high as 10 Mbps. I know the issue isn’t my network because my laptop gets >160 Mbps (It does have a different WiFi card though, an Intel AX210). After poking around I’ve seen some folks had success with disabling power management to solve this issue, but that hasn’t worked for me. I’ve also seen lots of people having issues with getting this card to play nice with Linux while others have had no trouble at all. Any help would be greatly appreciated!
