- Post your upstream and downstream signal levels. Click the link or type: http://192.168.100.1 or http://10.0.0.1 into your browser. We are interested in your power levels (dBmV) and your Signal to Noise Ratio (SNR). You may also want to contact Comcast and ask for your upstream SNR (uSNR) and receive level. - Post your modem’s error logs. - Post the make and model of your modem. - Post the make and model of your router if you have one. - Let us know if you contacted Comcast or had a tech visit. - Let us know what the lights on your modem are doing when you are having problems. - If you have already posted some of this information, you don't need to post it again.

I have been having the same T-4 timeout issue since moving here 12 days ago. Each time I call Comcast they tell me the wait time is 2 or 3 days for a tech to come out and look at my modem. The case was escalated last week, the escalation group decided to do nothing and close the ticket. They never contacted me. I think it is time to find another carrier, these people are spinning their wheels.
I'm having the same problem with the following equipment:
Modem: Motorola SB6121
Router: ASUS RT AC66U
