So far, their tech support is OK, but there's only been one problem.
There are two landline plugs (port 1 & port 2) on their modem. Hooked up one phone (1 wireless set & 1 hardwired handset) to each port, then tested by dialing out. The phone attached to port 1 worked fine; dialed out, connected & hung up. The phone attached to port 2 dialed out, got a busy signal and would not disconnect. Reset the modem and tested again, same results. Reset modem, swapped phones & ports, same problem - the phone on port 2 wouldn't work. Did a chat session with tech support, yep, seems like a hardware problem. Have an appointment for a tech to check it out next Tues. Maybe could have been faster service, but I'm not bitchin' about a few days wait.
Oh, and the guy who's to fix the ruts made by the line crew called today. He's working on getting the dirt ordered (says it'll be topsoil, not just fill dirt) and will be out ASAP - no firm date though.
