It's good that you've moved the thread to the correct mailing list.
However, I did already answer you and asked you some questions, to
which you have not yet responded....
What variables have changed in your test environment since last Monday?
If the answer is "nothing" , then the problem is more than likely due
to your cable company moving services around.
First, you should confirm that you still have clear QAM available...
assuming yes, then I recommend scanning for channels again, using each card.
