AX200 10 Second Pings on 5 GHz

polybutylene · 2020-09-03 12:43:01

Recently wifi with an Intel AX200 card has become unusable with 5 GHz. As stated in the subject, ping return times to the router range from 5 to 10 seconds. If I force the card to connect to 2.4 GHz by setting the BSSID then performance is okay. This problem has developed recently. I have also noted that the reported card temperature for the wifi module jumps about 10 deg C when I try running ping with 5 GHz relative to with 2.5 GHz.

I am currently running:

Linux peel 5.8.5-arch1-1 #1 SMP PREEMPT Thu, 27 Aug 2020 18:53:02 +0000 x86_64 GNU/Linux

Here are dmesg entries for iwlwifi. The card initially connects to 5 GHz. At timestamp [47292.587677] I disconnect and reconnect forcing a connection with the 2.4 GHz hardware on the router.

I tried disabling power management by adding the following lines to /etc/modprobe.d/iwlwifi.conf

options iwlmvm power_scheme=1
options iwlwifi power_save=0

I also tried removing the cc-a0-55.ucode firmware from /usr/lib/firmware and reloading the modules:

mv iwlwifi-cc-a0-55.ucode ~/firmware_backup/ 
rmmod iwlmvm
rmmod iwlwifi
modprobe iwlwifi

This made the card load cc-a0-53.ucode, but 5 GHz still does not work.

A duckduckgo search shows a history of 5 GHz/iwlwifi problems, but nothing that I can match to what I am observing. Other options I can try?

Here's what i get when running ping:

What is odd, is that all the return times are lagging. In the case above, after waiting ~5 seconds, then I see a returned ping every second with the same lag. It feels like everything is being buffered.
