You might want to log into the browser, select STATUS see if you are pulling a WAN ip address. If not, then sometimes, it is just a matter of power cycling the modem and router. Ie. remove power to the modem and router and then power up the modem first and let it boot up all the way. Next power up the router, in this sequence. Now see if you are pulling a WAN ip address from the ISP. If you are, then you are ready to go.
