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.
