Info Stuttering Bluetooth mouse - solution -Wifi antenna is also BT antenna

[pcx]

Just wanted to mention this solution to a badly stuttering bluetooth mouse, even though it is very specific and won't apply to many people, as the issue is very rare to be mentioned anywhere online.

I had a problem with a stuttering wireless mouse on a new system, and had read many of the threads and suggested solutions on the web.

The solution was to plug in the motherboard's external wifi antenna.

While it isn't documented in the motherboard's manual (Gigabyte B850M series), apparently the system's Bluetooth (on 2.4GHz) uses the wifi antenna.

Thus with no real antenna, only a crappy Bluetooth connection. I hadn't plugged the antenna in because I have my internet on Ethernet cable (and so also turned the desktop's wifi off.)

Thank you for sharing. This has actually come up before, but your thread is a good reminder for others to consider when experiencing BT connectivity issues.

PC is basically a shielded metal box (shielded from any electromagnetic interference).
How do you think bluetooth gets propagated? Through radio waves.

Obviously it needs an antenna.
And yes - it applies to every desktop pc with internal wifi/bluetooth.

Where you can omit external antenna:

Laptops have integrated antenna.​

Desktops with external USB/bluetooth dongle have antenna in the dongle.​

So last week I got this wifi and I really don't need the antenna because I have a direct ethernet line. So do I need the antenna after all for my xbox controller on bluetooth? The bluetooth on the PCIe card is connected to internal USB. The mobo doesnt have built in wifi.

Yes, connect the antenna for improved BT connectivity.

Indeed!
I just didn't know what was 'sufficient' despite that (and to what extent various grilles on cases would allow signals out), or how they might have solved that problem, or if some antenna was hidden among the back computer ports. In any case, the wifi antenna port had written "Wi-Fi" next to it but not Bluetooth, nor did the mobo manual mention BT, so there was no apparent need for the antenna if not using wifi...

Just to reinforce, technically the frequencies used for WiFi and Bluetooth are ALMOST the same. The design of an ANTENNA depends mostly on the frequency of the signals it gives. So naturally on a computer it makes sense that BOTH WiFi and Bluetooth use the SAME antenna sticking out of the back, and you DO need that antenna installed to use EITHER (or both) WiFi and Bluetooth.
