Perhaps check the manual to see if you can change some settings for a better connection?
Back when I was a kid I had a keyboard that was battery powered. Only during a raid the batteries would die. I’d be running around the house looking for double A’s. 🤣
I read before that it can be finicky when the battery is low! Might have to download some software for it too!
I got it working. Turns out the dongle needs to be placed in the USB extender and plugged in that way.
