C7800 cable works no internet no WiFi

C7800 internet connected No info in or out
I have a netgear nighthawk C7800. It just quit exchanging data over the web. Called xfinity the signal is good. We have cable tv in all rooms works fine. We have 4 computers connected to this router through a D-link switch. So cable into the router line out to switch. Cat5 from my laptop to router. Cycled power on router 4-5 times yesterday. Cycled power on all desktops and the switch several times. Computers all say connected to netgear. Phones al show full strength connection to WiFi. Netgear genie shows cable connection stays good. BUT here’s the kicker no information in or out. All web browsers time out and you must turn WiFi off on phones and use 4glte

    do you have a screen snip of your cable connections page and the logs? That helps us check the signal. Comcast is great at saying "the line's fine, it must be your equipment".
