Turns out that my motherboard's WiFi antenna is necessary for Bluetooth to work correctly (programming.dev)

I was troubleshooting Bluetooth connection today and I thought that this is somehow related to software (PipeWire, bluez, bluetoothd and all that stuff). But no. Apparently Bluetooth barely works when WiFi antenna is disconnected from my ASUS motherboard.

Anyway, this might save a lot of time for someone, so I'm posting it here.

Helpful post, thanks.

Having knowledge in electromagnetism it would seem pretty obvious to me that you need antennas to do the wireless-ing, but IDK what the average person knows.

Did that knowledge indicate how cell phones, which are much smaller than a desktop PC, obviously don't require visible external antennas to get WiFi and Bluetooth?

Yeah I don't blame people for not knowing since manufacturers hid them these days. Even wireless earbuds happen to have antennas covertly tucked in their tiny packages.
