ARRIS SB8200 Modem Provisioning
I went through Xfinity chat wanting to insure my modem was up to date. They pointed me to ARRIS support. Arris reviewed my modem settings and indicated the downstream channels were fine but there were problems with the upstream channels. I only have three out of four channels and the power levels were low. Power should be in the 45-51 range. Arris said this could cause drops and disconnections to get Xfinity to fix it. I passed this on in chat and Joseph said to call back next day to their "higher fix agency" to get it fixed. I called and after much effort by Alexandria she determined it was outside her ability to provision a non xfinity modem. My question is how do I get the upstream channels provisioned?
Couple notes. Cable comes from the pole to the house. From that point, I have replaced the cable to the modem (20'). There are no splitters.
Also, the modem as been rebooted by xfinity a few times and I have done the factory reset a number of times.
