I found out when I cancelled at&t that they have a software glitch in their modems/routers for 2 1/2 years now, but aren't trying aggressively to fix it, they keep changing routers until they find one that will work.... for a while... :banghead:
I don't use at&t anymore, but I think this router is going out... I'm gonna go around with pliers and make sure that all the connections are tight, then if it still is happening, I will call them to have someone check the line and modem... :evil3:
