Bought a mechanical keyboard (Epomaker TH108 v2 Pro). How do I fix the 2.4ghz dongle and keep it working consistently on Cachy OS? (programming.dev)

The keyboard stops working after a while of inactivity like watching a movie or playing a game. The keys light up, and the 2.4ghz indicator on the keyboard shows it's connected, but my pc doesn't detect any keystrokes. Only after I unplug and plug the dongle again, does it start working. How do I fix this? Is this an issue on the linux side, or should I return the keyboard and get a Keychron v6 max?

Is it plugged into a USB-A port that supports USB-3? Or near one that does? If you’re not sure, they are usually blue on the inside.

USB3 via USB-A ports has a well known interference problem at 2.4Ghz that will make small dongles unreliable. The solution is to only use them in USB-2 ports (usually black) or use a USB-2 only capable usb extension cable to move them physically a foot or two away from the ports.

In general though, I don’t trust wireless keyboards of any sort and am suspicious of wireless mice. I’ve had too many issues with them over the years.
