AR9271 no longer works with kernel 4.4.0-186-generic

Descrizione

On my laptop which uses trisquel 8.0 after upgrading to kernel 4.4.0-186-generic my wifi adapter no longer works. My laptop acts as if there is no adapter. If I switch back to kernel 4.4.0-119-generic it then works. On my desktop which uses Trisquel 9.0 the USB wifi doesn't work with kernel 4.15.0-112-generic in the same way.

My wifi is the Technoethical N150 Mini.

The WiFi chipset is Atheros AR9271, according to https://tehnoetic.com/tehnoetic-wireless-adapter-gnu-linux-libre-tet-n150

My USB dongle contains the same chipset, according to lsusb. It works with the kernel 4.15.0-112-generic in Trisquel 8's repository.

Is the package open-hth9k-htc-firmware installed on your system?

Did you mean "open-ahth9k-htc-firmware" ? That is installed on the laptop using 4.4.0-186-generic but wasn't installed on the desktop using 4.15.0-112-generic. Installing it on the desktop solved the issue. The laptop is still not seeing wifi networks with the dongle and new kernel.

So, the bug only affects the 4.4 version of the kernel, right? I updated the title accordingly. Can't you upgrade the kernel on the laptop system? You could install the linux-image-generic-hwe-8.0 package, in Trisquel 8's repository, to get the same version as on your desktop system.

Looks as though we've both been bitten by the same bug.

The solution looks deceptively simple. I can update the T420 clone, which hasn't yet
been affected, but I'll have to pass along the fix to the primary T420, whose WiFi
dongle[s] are not even recognized.

Is there a safe way of accomplishing this task with an ext4-formatted USB flash drive ?
I hesitate to install the fix on the clone, because I might end up with two non-functioning
WiFi connections ...

That solved it for the laptop now as well. Thank you for the help. Should I set the status to closed ?
