I have had Netgear C6220 and my internet is Xfinity and it worked fine last 9 months. Since last two days I get NO INTERNET on all devices (Mobile Phone, Smart TV, Laptop) although I am connected to wifi. When I restart my modem, I have a normal internet connection, after a few hours of inactivity like in the morning I have the same problem until I restart (turn off/turn on) my modem.Any one can help me?

Got a screen snip of the cable connections page and the event logs? Those help us check short term and longer term connection back to the isp.

The problem is via wifi, although i tried with inserting Lan to my laptop and it didn't work.I went out this morning and when I came back, I didn't have internet connection, when I retsarted the router, I have stable and good connection in all devices.I attached the logs and also the router LEDs below.LogsRouter C6220I took a photo when my internet connection was down while all devices were connected to router via wifi so you can see the LEDs on C6220 router.

Hi, I attached the screenshot of Logs below. Is there the problem with wifi channel or the hardware router problem?I'd appreciate it if you please help me. It is very confusing and it's interesting after restarting the router I have stable internet connection and no disconnect until a few hours of inactivity.Thanks. Logs

Same issue with me, had the c6220 on Xfinity for a couple years with no real issues, couple days ago it started losing connection, reset would have it working alright for an hour or so then lose connection again. I'm thinking it might be something Xfinity updated that's making the docsis 3.0 router not properly compatible with the highspeed service anymore. I just bought a cax80 to see if it fixes it, will update in a couple days when it gets here
