Just for the info..
While the tech a few posts up, shouldnt have canceled the apointment as a whole.. they should have come and checked things ANYWAYS..
Beyond checking the signals, and making sure the modem boots up and connects.. is about the extent of what they are able to do :(
The are not trained usually in anything networking, and have no control and knoledge in even stuff concerning the provisioning on the modems.. upstream/downstream channels, etc.
