Title:
iwl3945: Low throughput on focal / Linux 5.4
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello out their, I seem to be having some issues related WiFi on my
Xubuntu 20.04 install.
My main issue is that my WiFi connection on my Xubuntu install versus
my Windows 7 Starter install is a lot slower. Currently the highest
speed I have gotten on Xubuntu has been 10mbps, I was getting around
30-50mbps on Windows. I tried editing the default-wifi-powersave-
on.conf and setting it to 2 because that seemed to be a commonly
recommended answer, but doesn't seem to be helping. I have also tried
using "Additional Drivers" to try and see if their was another driver
available to no avail.
A user on the Xubuntu IRC chat (tomreyn) suggested a few things and we
collected this info about my wireless chipset, I hope it helps:

Thanks for any help in this matter!
