CM3000 stopped working
My CM3000 stopped working. I have a CM3000 cable modem, purchased Sep 11, 2024. Yesterday it stopped working. The second light down from the top (lightning) is the only one that is active, some...
Hi,
OK, I performed the reset using the paper clip via the Reset on the back of the CM3000. Actually several times.
I called Comcast my internet provider and had them provision the CM3000. They did. They ran diagnostics tests. They all passed.
However, the CM3000 still only has he Lightning indicator blinking and never comes up. This is its only behavior.
This sounds like a dead CM3000.
Most likely having to do with newer FW on the modem. You might make contact with NG support.
