I just bought a D-Link DI-524 a few weeks ago and everything was running great until a few days ago. Every few hours it just shuts the network down.... I lose the status, and the PC Activity light on the modem goes dead. I have to unplug the router from the power source, and unplug the Internet cable and plug it back into the router. I normally have to wait 5 minutes or so, and then plug it back in and all is fine again. Anyone know whats wrong with this thing? Is it the cable maybe?
