got a dlink DI-524, wireless router. It wouldnt detect the WAN at first, so I lowered the WAN speed in the config to 10mbps instead of 100. Then the wan light was blinking.. a little better.. then i clicked something I shouldnt have, and clicked renew DHCP. Now the host computer doesnt connect to the net at all, even w/o the router. How can I fix this? Would a system restore work? Also, whats the deal with the router?
