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.
Has anyone else had an issue using a USB Bluetooth device, and if you turned off the motherboard Bluetooth, the USB didn’t work either? That happened to me when I was using it, at least. Now, I haven’t tried since then, so I could be wrong now.
I had the same problem. Thought I was going crazy. The antenna is so ugly.
I had the same problem too, I ended up buying a USB Bluetooth transmitter. I figured the board was bad until I replaced it and had the same problem with the new one
You can probably stick the antenna on the back of the base so it’s not easily visible. Or get a separate one that’s a lot smaller.
It would be a waste to give them separate antenna, they both operate on the same frequency (and often with the same radio, although the BT side of an m.2 card is often supported by usb instead of pcie)
Huh. Interesting.
I never connected my “wi fi” antenna because I use a wire for the interwebs.
I would NOT have guessed that it is also used for bluetooth. I might use bluetooth.
Thanks!
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.
Most of the time Bluetooth and Wifi are provided by the same chip. Bluetooth runs on 2.4GHz, like WiFi up to N-band.
Edit: I’m too slow, looks like!
Wifi and bluetooth are often on the same chipset and share the antenna. You’ll see this on embedded devices as well.
To add: Bluetooth and WiFi both use the 2.4ghz spectrum. They are on the same chipset because otherwise you would need two antennas
same frequency, 2.4GHz, same antenna, quite often for chip that does dual wifi/BT the antenna is shared
