I have a C7800 Nighthawk WiFi router which loses connection to the internet at least 1-3 times a day. I've had Xfinity come out and test their connection and they haven't been able to diagnose any issues on their end. Also I'm not getting anywhere near the full speed (1 gb per second) that we should on both my wired computers connected to ethernet. Any suggestions on how to fix both of these issues? Thanks.
