C7000 Initial Channel Locking
I got a c7000 from someone that had upgraded to something newer, as far as I know it had been working. When trying to set it up with Comcast, they said they could see it, the self activate seems to work, when they sent reset codes to it, it lost downstream and upstream and attempted to re-aquire. However I never get an active connection, and they never see it as connected. When I go to the cable connection page, it says "Failure Your modem is offline. Please check the RF connection." Then, "Click Here to go to setting...". That link takes me to a very interesting page, showing 24 downstream and eight upstream channels, with only the first of each locked in. Even more interestingly, when the device is restarted it always starts at channel ID 31 at 687000000 Hz, power - 2.1 dBmV, SNR 40.9, which are all good values, but if I refresh the page every few minutes, the downstream channel that is locked in moves down one channel and by 6000000 Hz. Upstream does not appear to change, although I believe it has been different between different restarts. Also near the top of the page there is a startup procedure list: Aquire downstream channel, it reflects the current one locked in as described above; connectivity state, in progress params transfer complete; boot state, in progress unknown; security, disabled; ip provisioning mode, in progress unknown. I will try to post a pic, but I'm working off of my phone currently and the mobile interface is lacking attachments
