I am using an XPS 9360 where I replaced the Killer wireless card with an AX200 one. Now the signal strength is very low on 2.4ghz 10-15 meters from the modem (Bbox V3 of Proximus). I tried live environments of Manjaro, Mint but I could not even connect there and I tried POP and there it worked though same low signal issues. There are sometimes disconnects as well.
Issues persists in latest kernel and LTS Kernel.
What I already did:
- disable fast boot in BIOS. I am only running Endeavour, nothing else.
- downloaded latest firmware which is in use:
[x@x ~]$ modinfo iwlwifi | grep iwlwifi-cc
firmware: iwlwifi-cc-a0-66.ucode
This is a later version then what is on the dell page. Source: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree
output of sudo dmesg | grep iwlwifi | grep version:
[ 2.828643] iwlwifi 0000:3a:00.0: loaded firmware version 66.f1c864e0.0 cc-a0-66.ucode op_mode iwlmvm
- added the following in modprobe:
otions iwlwifi power_save=0
options iwlwifi uapsd_disable=1
options iwlmvm power_scheme=1
options iwlwifi enable_ini=N
What I have not tried yet:
- reset bios.
- reseat connectors of the wifi module.
- rebuild iwlwifi (bottom of the page here: https://www.linuxquestions.org/questions/linux-networking-3/trying-to-get-intel-ax200-wifi-card-to-work-in-debian-11-a-4175704711/)
Should I revert back to an older kernel or just use the driver of Intel?
