Frankly, that isn't your concern.
You paid for a service and it is up to the vendor to provide it. Via hard-wire, satellite, Bluetooth, or carrier pigeon, it doesn't matter so long as you get what you asked for.
They told me that I didn't need a tech and sent the boxes UPS.
This is the Hardest question that I have ever had to try and explain!
All of my confusion comes from the fact that I have FIOS in my man cave.
The tech used an existing cable in the wall to my FIOS modem.
This was after he installed the ONT outside, battery backup for the phone and then went into the attic .. to do something?
Now, I don't know if I only have FIOS in that (man cave) room and all of the other
in wall cables can only run comcast?
I am running comcast tv right now from the rooms that I want to run FIOS tomorrow.
I just don't know if when I cancel comcast tomorrow and activate FIOS .. will it run over those existing cables without me having to do anything else.
Unplug comcast boxes .. plug in FIOS?
