Hey I have always had a problem with my DSL. I have Sbc yahoo dsl. My problem is that it's always on blinking red. Unless I'm using the phone. Everytime I call SBC (or the new ATT) they always say it seems its working great. But my house is old. So is that the problem? Or just how things are connected. Can someone please help me on this problem? I really want to have my internet always to be working.
