I had to install the two modems (yes it is a two way) myself onto my computer. The installer had no idea whatsoever how to interface the two USB modems with the computer. One is for up and one is for downstream. While the house was being built I had them put the coax to the office room, so the installer did not have to run anything (thank god who knows how that would have turned out)
The installer sat there watching while I did it myself. Best of all, installation for this was not free, (i think i might have paid $149 for installation? does that sound right?) I am not a Sat. installer, I do other things. I should not have to help the installer, or completly do it myself becuase they know not what they are doing.
If memory serves me i remember the installer called the activation and activited the two modems before they were installed on the computer. I think the activation was complete after the modems were installed and communicating with the sat. I do not remember too well, it was a couple years back. The reason for using sat. internet was that this was in semi rural Montana (what part is not rural, seriously) and no other service (cable, DSL, etc) was around.
Point of the story, a lot of installers, (NO I DID NOT SAY ALL, SOME ARE VERY GOOD AT WHAT THEY DO), have no idea what they are doing. It would be a last resort for me to ever call back any sat. installer to do anything with my equipment or anything to my home.
