Nighthawk c7000v2 internet connection drops every day

[songboy56]

Every day for the past 2 weeks my cable modem/router will lose connection. I cant figure out what causes it and xfinity says every thing looks good on their end. It happens every morning around 10:30am or so. I reboot the modem/router and then everything comes back up.

Any suggestions?

Hardware version 2.01

Firmware version 1.03.03

those errors tend to indicate a line issue. 

do you have a screensnip of the cable connections page and the full event logs?

Here is the info...

[plemans]

You've got a lot of errors in your line and your logs are indicating line issues. 

Check the coax line for damage, kinks, old/bad/loose/corroded connections. 

remove any splitters, amplifiers, or signal attenuators in the line. 

Preferablly, move the modem to right where the coax comes into the home to prevent coax wiring in the home from behing the issue.

Thank you for the response. I do have the modem/router connection close to the wall where internet comes in. However, i use MOCA to connect to our office to provide it direct internet not wireless. So there is a splitter in line from the wall to the modem/router to make that work. Is there another way to hook up the MOCA so it can still work?

[plemans]

Try it without and see if the internet networks fine. 

I've seen sketchy moca adapters put interference into the line.

Yes I'm going to try that when i get time today. Thank you.
