Wanted to add a WiFi+BT to my X300 Deskmini, so I went and bought the Intel M.2/WiFi+BT AX210. Was about around 25€ on eBay.
Well, some strange thing happened.
The module is recognised all right. But the Bluetooth performance is subpar, almost nil.
WiFi reception and range, same weak signal and detects only my close AP.
I have EndeavourOS with the latest updates, tried a few things to alleviate this issue, but it seems that AX210 has a compatibility with the AMD platform or something is amiss.
Tried switching between Zen and mainline kernel. No dice, same thing.
lspci detects the WiFi card properly, but only after I downloaded the latest Intel driver and copied it into /lib/firmware.
Booted the computer with a live USB with Fedora, PopOS, same thing.
Have I got a dud card? Is there something what I could try to solve this?
