Title:
iwlwifi - very slow for intel 9260/9560 wireless cards
Status in linux-firmware package in Ubuntu:
Incomplete
Bug description:
I have tried 2 intel wifi cards (9260 and previously 9560, which i
thought was broken) in my msi GF63 laptop. Both cards work fine when
using windows, getting me a speed of 450 mbps consistently.
But when using linux with ubuntu 20.04, this speed is reduced to max
25 mbps (using the same 5G network).
I'm using iwlwifi-9260-th-b0-jf-b0-46.ucode and kernel 5.6.19.
I have tried with a previous version of the driver
(iwlwifi-9260-th-b0-jf-b0-34.ucode), but unfortunately gave me the
same result. I have also tried different kernels (5.4.0 that came with
ubuntu 20.04 and also 5.3.18), to no avail.
I've also tried fiddling with settings in /etc/modprobe.d/iwlwifi-
opt.conf
options iwlwifi 11n_disable=1
options iwlwifi swcrypto=0
options iwlwifi bt_coex_active=0
options iwlwifi power_save=0
options iwlwifi uapsd_disable=1
options iwlmvm power_scheme=1
These seem to get me the 'best' results, of merely 25 mbps.
windows, when getting 450 mbps, uses this driver version 22.0.0.6
(https://downloadcenter.intel.com/download/29902)
I have disabled power-management so i don't think it's a power save
issue like someone else suggested.
From iw and iwconfig, the max bit rate seems to be 54.0 Mbps, but the
card can surely do much faster.
Any idea on how to fix this? Please let me know if more info is
needed. Thanks!
