This is endemic to the GSX9865. From the other thread on this, apparently this was fixed by Comcast a couple years ago, but somehow the software fix has never made it into the Contour 2 boxes.
The solution is to switch to an Arris CMX013.
Catch-22 - they will not give you one. They will promise it. They will "order' it. They will "locate" it. And then they will give you another GSX9865 that will do exactly the same thing.
Apparently, there is NO WAY in their ordering system to actually order one. They order by some generic code and you might get one box or the other. Except that... in reality... you won't get an Arris.
I went round and round with that circus and finally cut the cord. And I am very happy.
