CM1100 on Xfinity - worked for a few minutes and then only the two LAN lights are lit amber
Had a very difficult time activating because the modem would keep resetting on its own. Finally got it working and did some speed tests to verify. It seemed more stable after activation. Shut down...
Seems like the unit is bad. Get it returned and find another one.
Sounds like a hardware problem.
Where did you get it?
I'd probably exchange it if its a new purchase.
Try disconnecting the coax from the modem, then try factory resetting it while its powered on.
Are any of the other led's on? color? solid/blinking?
No other lights are on, not even the power light. Just the two LAN indicators lit amber. That's not something mentioned in the troubleshooting section of the owners manual. I haven't tried disconnecting the cable while doing a factory reset, guess I'll try that next. It's a new modem from Costco, so it that doesn't work, I guess I'll try to return it. It's been a few weeks since I bought it since I had to wait for Xfinity to run a line from the street to my house and then one inside my house. I've spent hours on the phone and chat sessions just getting the cable installed and now this! This is one of the Xfinity-recommended cable modems, so I don't know why it's giving me such problems.
Okay, unable to get it to reset whether the cable is plugged in or not. I've got it powered off and will try again tomorrow before deciding about returning it.
Since factory reset isn't even working, I tend to think it's a hardware problem.
