I was having problems with my rented router from COX - the Cisco DPC3825. The problems were intermittent but occasionally my computer would be dropped from the WiFi throughout the day. I also had streaming problems watching video on the tele. I finally decided to visit a COX store today and have it switched out for a new one. They gave me a NETGEAR CG3000D-RG.
'Great', I thought.
I get it home, put it in and in the last hour the WiFi has dropped connection a dozen times. I look at the router and it has reset itself. It resets itself every few minutes. Everything connected to it loses connection.
I have no idea what to do next.
