OK, I got a new WIFI/bluetooth m.2 card and I need to take the time to install it.
My WIFI works in my computer, but the Bluetooth, which is on the same card, stopped working months ago. I've been using a Bluetooth dongle instead. The Bluetooth dongle doesn't have the range of the m.2 card though (when it was working), so I bought a new card to replace the old one.
The new card is an Intel ax210ngw. I hope it has good signal strength.
