Well yes, that is a lot of devices, but most are wireless, and run with no problems with wifi router nor any problems with older router until it started to glitch out. only three wired devices, TV, Apple TV, and then through the switch to two computers. And TV and Apple TV are not usually running till at night. All this worked fine with the old router until it glitched out. So I am still trying to understand why this new router slows down my inertent connection after 20 minutes.
