| Hello daveangell20 and welcome to the BBR Comcast HSI forum.
How are you posting now, if you can't receive a signal?
Can you provide more information about your connection, overall? When you try to connect your cable modem to your PC, what are stats of the cable modem lights in front?
- Are you behind a router? If so, what type?

| That's a good question, SuperNet33  .
daveangell20 - you need to register your cable modem. This FAQ here should instruct you on how to do so.

| OK - your region must've recently switched over to the new provisioning systems, for cable modems. For a more "detailed" summary about the new system, check this FAQ.
As for your signal levels - your upstream channel is out of range (Please, refer here for acceptable signal levels). How many splitters is your cable modem behind?

Littleton, CO | My cable modem is behind 1 splitter. I dont know how many times Ive talked to comcast, they cant seem to figure it out. I have a technician coming to the house tomorrow so maybe he can figure it out |

| OK - let's try doing some troubleshooting here. Remove the splitter your cable modem is behind, and connect the cable modem to the drop line. Now, check your signals afterwards at: »192.168.100.1 - copy and paste them here.

Just making a comment for kicks.... My cable modem from Comcast has an internet button on it that if you don't press to turn it on, it blocks all traffic but shows connection to comcast. May want to check to see if you have one of those buttons.

Your signals look fine ... for now. Though, your transmit power (Tx Power) is at the DOCSIS borderline. Is the modem able to sync, yet, or still out of luck? |

Littleton, CO | The comcast tech came out today. He got it all figured out. There was a filter on the line outside of the house. Im online with comcast now. Thanks for the help |
