CM1000 Xfinity issues

Well it is finally fixed.  The tech showed up today and I showed him the two frequencies that were having the problem.  He checked outside, and then at the tap.  He came into the house and said he needed to call a bucket truck in to fix it.  I got a recorded call from Comcast that they were working to fix the issue.  I got a second call an hour later that the issue was fixed.  I ran a speed test and got a consistent 160mbps (yay!).  I used the reset button on the modem and let it re-provision.  All the signal/noise and power levels were good and there were no uncorrectable codewords.  They didn't tell me what they fixed, but at long last, it is fixed.
