Wifi and bluetooth are often on the same chipset and share the antenna. You'll see this on embedded devices as well.

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.

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!

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!

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)

I had the same problem. Thought I was going crazy. The antenna is so ugly.

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.
