I installed a new mobo, Asus ROG Strix B550 Gaming-F Wifi II a few weeks ago. Every once in a while when i boot up my system my bluetooth mouse and keyboard will not be connected. I though initially that maybe I just had to turn on the mouse and keyboard before I turned on my PC, thinking maybe the devices were timing out or something and that seemed to work for 2 weeks but now just this morning they didn't connect. Luckily I also have a crappy wired mouse and 2.4Ghz dongle for the wireless keyboard and was able to log into Windows. I had to turn off and turn on bluetooth and then it connected. This is a clean install on Windows 11 and it is updated to the latest version. The mobo BIOS and chipset are updated to the latest versions. My mobo uses the wifi antenna as a bluetooth antenna and i sit only about 2 feet from the antenna so I don't think it's an interference issue. As far as the bluetooth driver it is updated to the latest version. The mouse is a Logitech MX Master 3S and the keyboard is a Logitech MX Keys.
