Hello, how are you?

I would like to contribute with more information regarding this issue. I recently had to format my computer, which was already using this repository as a driver (but I don’t remember the commit I used back then, as it was installed over a year ago), and after downloading the most recent commit b44d288 the driver doesn't work.

I checked the open issues and found some references to using this commit 63cf0b4 and it actually works. However, I am unable to list my 5GHz WiFi. On Windows, it works fine.

I tested this on the following distributions: Debian 12, Ubuntu 20.04, 22.04, 24.10, and Fedora 40.
