Staying with family this weekend and I noticed their gateway is not locking all the available upstream channels. As seen on the status page, it sees the channels no problem and power levels are within spec. This has been a problem for at least the past month and I was hoping that it would clear up on its own. Rebooting the XB6-T router is not solving the problem. Thinking it was a plant issue, I brought my MB8600 and tested it here and it locks all three channels without a problem. Any suggestions on what to do next? Trying to avoid calling Comcast on this one. Other than not getting the full 35Mbps upload on their Gigabit plan, there haven't been any actual connectivity problems.
