Called dtv tech today to ask why everytime i plug phone line in dvr, dsl goes down. The techy said I was plugging it in to the wrong port. He said I was accidentally plugging it into the EEETTHHHEEERRNNEETT plug. He said it slowly so i knew what the word was. When I told him that was not possible because of the wireless adapter that was plugged in there he said "that port had not been turned on". I told him i had been using it for months and he asked me if i had modified my box. I let it drop and asked him about a possible bad ground and he said it is grounded. If it wasn't you would get no reception. I thanked him for his time and hung up. I was not mad but expected a bit more from dtv tech. My only complaint is that if I wasn't regularly reading this forum I would totally believe him. I am no techy. I usually read the how to posts 3 times before trying anything new. Maybe they should suggest that their techs read the forums here or anywhere that has dtv real techys on it. P.S. changed bad dsl filter and now does not interupt dsl but call id screen says i need to subscribe even though I do.
