TP-LINK TL-WN422G not working

[hernans]

Hello everyone,

I just installed OpenSuse (Tumbleweed) for first time. I cannot connect to Wi-Fi using a TP-LINK TL-WN422G. After trying for a while I just plugged another device (from a different vendor) and worked flawlessly. The TP-LINK TL-WN422G worked fine in other GNU/Linux distributions which were replaced during the installation.

I am not an expert but it seems to me that the device is properly recognized and the kernel modules are loaded:

sudo dmesg

[11054.080314] usb 1-9: new high-speed USB device number 4 using xhci_hcd
[11054.347819] usb 1-9: New USB device found, idVendor=0cf3, idProduct=1006, bcdDevice= 1.08

[11055.794575] ath9k_htc 1-9:1.0: ath9k_htc: HTC initialized with 33 credits

However, no interface seems to be created:

sudo iwconfig
lo        no wireless extensions.

enp10s0   no wireless extensions.

and I cannot see the Wi-Fi networks that are close to the computer.

Digging in internet I found the following thread https://lkml.org/lkml/2020/6/26/432 that makes me suspect that the problem is in the latest versions of the kernel. In such case I would not have any problem with downgrade the kernel if it can be done in a simple way (I am using the nvidia drivers from the repository, I need them because the Nouveau driver did not work properly)


Is there any way to solve this issue?

Thanks in advance

Thank you for your answer. The command returns nothing at all. After removing the adapter that is working, and plugging again the TL-WN422G I get (dmesg)

Thank you. I already have rfkill installed. Both commands gave no output, i.e.:

myuser@localhost:~> sudo rfkill list all
[sudo] password for root: 
myuser@localhost:~>

I also find this post which may be useful:

I think you're best advised to wait until the necessary reverts are done....

For the moment just use the wifi device that works.

Thank you. I am going to wait as I wish to migrate at least two other PCs to OpenSuse Tumbleweed. I really liked the way in which some OpenSuse tools were designed and I am very impressed with this distribution.
