Still waiting to see how everything pans out- our internet was installed on a Tuesday. Two days later it quit, mid Netflix show. After trying to reset the modem, I called tech support and they sent a new modem. The new modem didn't reach outside the living room. Our house is only 800 sq ft, so it shouldn't have had a problem reaching the whole house. We called tech support again and had a service technician come out. The issue was the modem, again. The tech told us it was an old model they didn't use any more and gave us a new one. We haven't had any problems since, but it's only been a few days.
