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.
I usually connect it as a backup/so I don’t lose the antenas but im also mostly wired. Good to know that it helps with my Bluetooth as well. Being able to easily hookup your phone to pc via Bluetooth is underrated. Especially via the phone link windows app, so many features and things you can do when you have em hooked up.
