Hey all. I changed from cable (Comcast) to dsl (ATT) a couple of week ago. and everything was going fine. Last night the router stopped seeing the internet. I ran the Dignose Tool in Window's, it said there's trouble with the IP Address. The Net is working fine without the router. Help. ATT told me there were alot of error packages on my line and they are looking at that. They also want me to use their router to do Tech support. should I just change it out?
