No Ranging Response received - T3 time-out

I definitely apologize for any inconvenience caused by all of this. It sounds like you've been dealing with more than your share of connection issues based on what you've shared so far. The T3 errors you're seeing would indicate a 200ms loss of upstream connectivity. A few occasional such errors won't usually be noticed but if they occur frequently enough that would suggest an equipment or signal issue taking place. I do also see the modem appears to not be bonding to one of the upstream channels available. There's certainly a few things that can be tried to address that. I'd suggest starting by checking all of the connections to ensure they're hand tight still and if that doesn't help you can try connecting the modem at other outlets in the home. In the event that none of that helps we can review your account with you further to see that options are available. Feel free to email us at cox.help@cox.com should these service issues continue.
