AR9271 USB 2.0 freezes multiple times in managed mode

[turbodat]

AR9271 USB 2.0 freezes multiple times in managed(client) mode while trying to download large files of about greater than 600MB AR9271 freezes with ssid in the network manager and becomes unresponsive until unplugged and repluged and later for some time it works and again it continues to freeze

Distro : Debian XFCE (testing)
Kernel version : 6.1.7
NetworkManager Applet version:1.30
driver package used: firmware-ath9k-htc (1.4.0-108-gd856466+dfsg1-1)

and the result is even worst in stable release of debian where it freezes multiple times even for downloading files of 100MB the card dies with no led light and the network manager completely becomes unresponsive and need to unplug the usb and replug to make it work again and the cycle of freezing continues after sometime.

Distro : Debian XFCE (stable)
Kernel version : 5.10
NetworkManager Applet version:1.20
driver package used: firmware-ath9k-htc (1.4.0-106-gc583009+dfsg1-1)

The driver package used are from official repo.I thought usb is dying and I also tried with another ar9271 usb adapter and the result was same.But Adapter works great on windows.

The problem is same as this post qca/open-ath9k-htc-firmware#173
and I don't think posting their could help since the issues are not solved.So posting it here
I read in one of the post that you have couple of ALFA AWUS036NHA adapters So can you test with your adapter

Thank you for your patience for reading this post.

Hi @turbodat

AR9271 USB 2.0

I do have two adapters with that chipset so let me do a little testing to see what I can find out.

I don't have anything that I think will help. Maybe somebody has something.

I would try a different cable.
