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.

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.
