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.
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.
