Motorola MB7621 Upstream blinking

I'm having a issue with MB7621 modem upstream connection no longer going through after a recent storm passed that cause an outage. When service didn't come back on, I checked my Xfinity account to see that my modem had been removed and couldn't be re-activated, I had to use the support chat to have it added.

First, check here for info on any possible local outages;

Use a cell phone service, a public WiFi hotspot, a neighbor's internet if you need to, to check it.

No outage in my area at the time of the post or now. The modem stopped working when a thunderstorm passed over my area 2 days before and caused an outage in the area that night which Comcast said was already resolved.

O/k the status shows that the modem is not locking in / achieving block sync with the Comcast system. You may want to call in to 1800comcast and get a tech out to investigate. Perhaps some line equipment upstream of your premises got fried by a lightning strike. Good luck with it ! Please post back with how things turn out.

Incase anyone had the same issue, with upstream connection being down. The issue was resolved with a home visit, the tech had to replace the cable from their equipment outside to inside the house. Was told by the tech that our cable was going out, hence the connectivity issues.
