I just got off the phone with AT&T. According to their diagnostics, the internet signal they're providing is sound from their perspective. I can logon to the internet and my modem seems to br functioning correctly, but I frequently lose my connection and am having to constantly shut the modem down and reboot.
According to AT&T, there are some settings in my wireles modem / router that are unique to ATT. I have a Netgear N150. I've looked on the internet and I can't find anything.
