Yesterday I have reinstalled windows, and my wireless (Natural Wireless Ergonomic Keyboard) started missing keystrokes and having delays. I have followed instructions here (paired the device without much luck (pairing worked fine but keystrokes are still playing up), changed batteries, etc.).
Same windows version, tried different USB slots, I am certain batteries are new, I have turned PC on the side for direct visibility between keyboard and receiver and its 2 feet away from keyboard ATM. It does work, but then every minute or so it stops for 2-3 seconds (sometimes 10-15) then works fine again or delays the keys pressed by a second or two.
Also downloaded IntelyType driver but it says it's up to date.
Keyboard is quite old and it could be just a coincidence that it started dying same time that I have reinstalled OS.
Does signal deteriorate on old keyboards? How do I check what is causing this?
