Nighthawk c7000v2 internet connection drops every day
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...
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.
