Yes, it was their modem I switched it out for. I called them after I pluged it in and they sent the test signal and still could not pic up my modem.
I’m confused when they say that because I had no problem getting the cable TV reception thru the same outlet.
Well then I am betting you have a signal loss somewhere, are you sure that same line isnt being shared with a tv or two? Quite possibly you may have your cable box outside the house changed by the cable co or they route you a new cable from it.
