Hey all, this seems to be related to the kernel itself…
Any kernel above 5.9 my wifi upload speed is completely nerfed, download remains fine at about 230mbit but upload drops to 2-7mbit. Kernel 5.8* works fine. I’ve tried disabling power saving thinking maybe it had something to do with that, but no dice. Even tried kernel 5.11.
Have a dell xps 9300 with killer 1650 network card. I’ve tried to do a bit of searching and found maybe one other recent mention of someone else having issues potentially with this as well.
Anyone have any suggestions that I could give a whirl?
Thanks!
