 You should first determine whether the router is able to obtain a WAN IP address from the ISP. Or you have
been assigned a static IP address.
 Check the IP address for the WAN port.
 If your ISP requires a login program as PPP over Ethernet (PPPoE), ensure the user name and password you
enter are correctable.
 If your Broadband Wireless Router is set to routing mode and you use private IP addresses on the LAN, make
sure Network Address Translation (NAT) is enabled.
 Your PC may not recognize any DNS server address. Check your DNS setting on the Broadband Wireless
Router.
