I was just thinking when I read your post how much I hate having repair men in my house and will go to all costs to not have them come in. One of the times my computer went out I discovered it was the phone jack. My male dog probably used it and I did not know it, and it burned out. yeah, dog's wetting on cords is never a good thing. Hopefully it is something outside like mentioned before. Mine is supposed to be high speed, lol, yep, high speed dial up.
