This issue is fixed with kernel version 5.4.49 (current longterm kernel). I was having the exact same issue for almost 3 months. My Wifi speed used to get throttled whenever I download something or just consume more bandwidth continuously. More importantly whenever the throttling happens, the laptop also freezes for a few seconds. During these 3 months I tried several iwlwifi configurations, changed its driver versions... etc. Nothing worked.
But then updating the kernel from version 5.3.0 to 5.4.49 manually fixed the issue. Now the wifi works perfectly without any issues. I haven't faced any other issue with this kernel yet(I am on Ubuntu 18.04). Also, now I couldn't see any iwlwifi error messages getting reported in dmesg logs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848921 Title: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848921/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
