try this then: Unplug ur connection...i mean pull the plug on ur modem so all power is off, do this while ur pc is off as well. leave all off for a couple mins (only takes about 30secs to reset but just to be sure), then plus everything back in, in this order: modem frist (let it completely turn on and connect..takes about 30 secs)>router second (if u have one, do the same as for the modem, let it connect)>pc's last (if u have more than one). Check ur network settings again to see if u have an IP. If not try again what i wrote up top.
