A couple of weeks ago my internet connection began disconnecting and reconnecting several times a day. The disconnects seem to be more frequent when more bandwidth is being used. Every time it disconnects the DSL light on the modem blinks red momentarily, and soon returns to normal. I've tried two different modems and they both do the same thing. I have tried multiple cords with the modem. I contacted AT&T and they said they ran a line test and it looked normal. There are 4 computers sharing this connection and the router is a Linksys WRT54G. This pretty much ruins my online gaming experience and is just a pain when browsing. Any ideas?
