Hi @aikidzin

That confirms that your system sees the adapter.

When you ran sudo sh install-driver.sh , did you see any problems noted? If would be good if you could run the following and copy what is posted to the screen during sudo sh install-driver.sh .

sudo sh remove-driver.sh
sudo sh install-driver.sh

Does your computer have secure boot turned on?

Hi @morrownr
Yes, the problem was in SecureBoot option. I changed from Windows to debian and after reboot everything went well.
Wifi is connected. Much thanks!
BTW, during installation there was no any errors. I just installed as in manual in Readme.

Great. It is possible to use this driver with SecureBoot but how depends on the distro. However, unless you have a good reason to use SecureBoot, I think it is easier just to turn it off.

For what it is worth, once you get to kernel 6.14 or later, there is a really good in-kernel driver for your adapter so your adapter will be plug and play and no more hunting and fussing about drivers.
