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.
I have this CM1100 on Xfinity for a month so far. We have the network disconnected this morning and I checked the model and saw the two LAN lights were amber. I powered it off and on, then he network restored but aminutes later, it happened again and again for a few times.
I guess this is the hardwire issue and going to get a new one from Costco to test it.
Have the ISP check the signal and line quality UP to the modem.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.Be sure that LAG is disabled on the modem.

I do have cable lsplitters between the modem and ISP service box and I have this setting for many years. even the new CM1100 modem has been working well for a month. Today was the first time I faced this issue. and I did power it off and on a few times( 3 or 4 I forgot it ) and got the same error each time, and finally it works and so far it has been in good shape this afternoon. I will pay more attention on this and will order another one as backup. as all stay home these days, the internet is essential now.
Splitters can cause noise or lower the signal on the cable line to the modem. These are not recommended if possible.
