Followup.
Charter failed to show when scheduled. I called them and they said they had no record of the appointment. When I explained how they had failed to show for a survey either time it was scheduled and offered to go satellite instead, they got active very fast.
Installation was scheduled for the next day and the man arrived early. He installed an exterior box, ran wires from the box outside to the central box in the garage (and made them inconspicuous), hooked up all 8 cable links, and checked signals.
The phone was supposed to be a separate install, but the man here for TV and internet said he could do it and he did.
So everything is up and running.
Charter offers 8, 16, and 25 meg service for internet. I ordered the 16 so we can stream Netflix to our BluRay box and TV. When I tested the speed last night, it was coming in at 25.96 meg! Yes, we are only paying for the 16 - the technician said to expect speeds "considerably faster" than what we ordered.
So everything is up and running very well and I am happy.
