Since I own a Tuxedo Aura 15 Gen1 I had some serious Wifi speed problems (using the built in Intel AX200 chipset): being connected over Wifi the download speed was terribly slow. With some tweaks I just managed to reach 20MBit.
While there are many threads out there about this topic (mainly on Reddit) none of the solutions worked for me. After upgrading to Ubuntu 22.04 I hoped this issues would disappear (due to a more recent kernel), but literally nothing changed.
Finally I found a kernel module option which unleashed the full speed of the built in Intel AX200 chipset. You need to put the following configuration to the
iwlwifi kernel modules (e.g.
1 2 3 4 5 6 7 8 9 # /etc/modprobe.d/iwlwifi.conf # iwlwifi will dyamically load either iwldvm or iwlmvm depending on the # microcode file installed on the system. When removing iwlwifi, first # remove the iwl?vm module and then iwlwifi. remove iwlwifi \ (/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \ && /sbin/modprobe -r mac80211 options iwlwifi disable_11ax=Y
After saving this file, you just need to re-load the kernel module by executing the commands:
1 2 $ sudo rmmod iwlmvm iwlwifi $ sudo modprobe iwlwifi
