[Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[eric norris]

Dear Gang:
Xfinity, our internet provider, showed up at 7:30am this morning, to explain to the XYL that we were being cut off for good because my amateur radio activities had caused wide area outages.  Oddly, these wide area outages did not include my own house.  They told her the antennas themselves--absent any power--were the problem
The last time I was threatened, I installed chokes and opto-isolaters on our shielded ethernet lines, and after being told they use 14Mhz as their carrier frequency, I have stayed off 20m, only using 100w unless I'm in a rare contest.  I asked to speak to a technical guy--they gave me a number which I called, but he never called back.
Any Ideas?  Does anyone have a contact at the ARRL, or know a communications lawyer?  Comcast/Xfinity will be back out here at 2pm Pacific time--I'd appreciate any help.  
My XYL depends on an internet connection to work.  Being off the air is unimaginable.
Frantic,

73, Eric WD6DBM
