I have a TPLINK TL-WR841N wireless router. It used to drop connections and I would power cycle and then it would start working again. But now it has started dropping connections literally every minute. I recently added two echo dots and a nest to the network. When I look at the router page I see there are 7 devices connected which is expected. I connected directly to the modem and got good connectivity. Are 7 connections too much for the router to handle?
