While there is more supported devices using that spectrum I don’t personally have that many of them running at any point in time so I’m not convinced that’s the main cause of the problem. I suspect it’s more due to wireless keyboard / mice being lower powered than they used to be so they can support longer battery life and lower profile USB dongles.
