What’s the best way to replace unreliable Bluetooth for wireless controllers on a desktop PC?

For gaming from a TV, I’d seriously consider a controller that uses its own 2.4 GHz USB receiver instead of Bluetooth. Those usually have a more consistent connection for gaming, and you won’t need to troubleshoot the PC’s Bluetooth hardware. A wired controller is another reliable option, although you may need a longer USB cable or extension to reach the TV setup.

I’ll be gaming from the TV, so using a USB extension isn’t a problem. I’ll look into controllers with their own wireless receiver since avoiding Bluetooth altogether sounds more reliable.

A USB Bluetooth adapter is probably the simplest replacement. Since the PC case has a lot of metal around it, use a short USB extension cable and place the adapter somewhere with a clearer line of sight to the controller. That can help more than plugging the adapter directly into the back of the computer. Before buying one, you could also try updating the existing Bluetooth drivers and moving the adapter away from other USB 3.0 devices.
