CM1150V LED says Partial Service, but all channels locked
I initially had some "partial service" issues, where only (2) of (4) upstream channels were locking. The GUI said "partial service" above the channel lists, and the upstream light was flashing -- and I really did have "partial service" at that point. But a Comcast tech came to the house, removed a noise block at the pole, and now all channels are locked.
So now, with all provisioned channels are LOCKED, the GUI no longer says "partial service". But the CM1150V's upstream LED is still flashing.
Why would the upstream LED flash, when all provisioned channels are locked? I'll paste the channel status below, all provisioned channels are LOCKED but the US LED is still flashing, flashing, flashing. WHY???

I recommend you guys contact your ISP. They have control over how this modem gets associated with there sysetm. Have them look in to there logs.
Has a reset been performed on the modem yet?
I have been in contact with Comcast, and verified that ALL PROVISIONED CHANNELS ARE LOCKED -- upstream and downstream. And yes, the modem has been power cycled, and even factory reset multiple times. Always same result.
All provisioned channels are locked, and the modem's GUI does *not* indicate partial service -- nor are there any partial service errors in the logs. But the upstream LED is still flashing.
Looks like a firmware bug to me. Odd that Netgear won't answer.
It's probably a HW problem. I would try another CM1150v.
Others have not methioned this and FW comes from ISPs after NG give it to the ISP to test out on there system.
File a support ticket here then:

Hopefully someone will take a look.
