N750 WiFi Router
If your router is still unable to obtain an IP address from the ISP, the problem might be one of
the following:
• Your Internet service provider (ISP) might require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of
login.
• If your ISP requires a login, the login name and password might be set incorrectly.
• Your ISP might check for your computer’s host name.
Assign the computer host name of your ISP account as the account name in the Internet
Setup screen.
• If your ISP allows only one Ethernet MAC address to connect to Internet and checks for
your computer’s MAC address, do one of the following:
- Inform your ISP that you bought a new network device and ask them to use the
router’s MAC address.
- Configure your router to clone your computer’s MAC address.
If your router obtained an IP address, but your computer is does not load any web pages from
the Internet, it might be for one or more of the following reasons:
• Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www
addresses) to numeric IP addresses. Typically, your ISP provides the addresses of one or
two DNS servers for your use. If you entered a DNS address during the router’s
configuration, reboot your computer, and verify the DNS address. You can configure your
computer manually with DNS addresses, as explained in your operating system
documentation.
• The router might not be configured as the TCP/IP gateway on your computer.
If your computer obtains its information from the router by DHCP, reboot the computer
and verify the gateway address.
• You might be running login software that is no longer needed.
If your ISP provided a program to log you in to the Internet (such as WinPoET), you no
longer need to run that software after installing your router. You might need to go to
Internet Explorer and select Tools > Internet Options, click the Connections tab, and
select Never dial a connection. Other browsers provide similar options.
