ath9k doesn't stop freezing several times in an hour

[lutzig]

Good morning !

several times in an hour I have to reactivate the Wi-Fi cause the speed falls to 1 Mbt/s.
I've done all checks concerning the Livebox - everything is OK.

hi @lutzig . This repository for ath9k-htc firmware, which is used on ar7010 and ar9271 USB WiFi controller. Your question seems to be related to AR9485 PCI WiFi controller, which is not using ath9k-htc firmware and not using ath9k-htc kernel driver.

Hi Olerem!
Do you want to mean that there is here nobody who could help me ?
Do you know where I could find some help, please ? Since the upgrade to UBUNTU 22.04 I am looking for it and I find nowhere else that here :o... And that's getting on my nerves...
Thank in advance.
