Then it is proably better just to reset the router and modem.Unplug the modem for about 45 sec or so.While you are doing this get a paperclip and press the little reset button on the router.Power up the modem wait for it to boot up then release the reset button.This will reset it to factory defaults.Then go into the router set-up page.Do this through a computer that is wired to the router.Do a start/run/cmd ipconfig and wright down the default gateway.Type that address in the address bar of your broswer and that will bring you to the router set-up page.Depending on what router it is,is what the default password is for the router.Then set-up the router the way you like it.There is also a staus page it the router set-up make sure it is getting an IP from the modem.
