Put in for my new XL4. I know, I should have done it myself, but they insisted on doing it. I figure if I persisted that they wouldn't give me much help on pairing. Besides, the office is all the ways across town and I worried about having to travel for multiple M cards. What pisses me off is I know more about this than the tech who claimed to have done many card installations. He knew jack about MOCA. I had to instruct him on installing a splitter BEFORE the tuning adapter after he had lost the MOCA Internet connection. He was flabbergasted that I was "using" the cable company's wires for other than normal TV. In any event he took quite a while, much of it on the phone. I wonder how I would have fared on the phone.
