I am a new Comcast customer who had internet and phone service installed just yesterday. (Waiting for confirmation of fiber optic in my neighborhood before I get TV service. )
The question is about the wire cable installed from the signal source at the rear of my house around to the front office where my computers are. I have just remodeled my older home and have painted and prettied up the exterior. As part of this, I had a professional some months ago rewire the various existing wires and cables under the eves for a neater appearance. The Comcast contractor yesterday insisted that running the internet cable from the back of the house to the front would best be done over the fascia and across the roof. When I asked to run the cable around the house under the eves with the rest of the wires, he said that the extra 20-30 feet of cable required for this "could" deteriorate my signal to such an extent as to lower speeds considerably and that I "could" be unhappy with the result. I have little knowledge of these matters, so I immediately called a tech at Comcast and she rather unconfidently said yes, that 20-30 extra feet "could" have such a slowing effect. Her supervisor said the same with the same lack of conviction: it "could". Now Ilive in the desert Southwest. It was hot outside. My conspiratorial side comes out and I wonder if the contract installers were just trying to avoid all the under-eave stapling, get done with the job, and get home. Were the Comcast techs beyond their depth?
And every Comcast person I spoke with said "could" too many times. When you think about it, almost everything in the world "could" happen. For those of you with more knowledge of these matters than I, "could" the speed be slowed by a few extra feet of cable? If it "could" be, how much and how likely? Incidentally, I am quite happy with the speed - nice, but I just don't like that big black wire running over the roof and down my newly painted fascia.
I thank you appreciatively for lending me you thoughts.
