2. Access the wireless modem router interface at http://www.routerlogin.net.
3. Select Administration > Router Status.
4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your wireless
modem router has not obtained an IP address from your ISP.
If your wireless modem router cannot obtain an IP address from the ISP, you might need to
force your cable or DSL modem to recognize your new wireless modem router by restarting
your network, as described in
If your wireless modem 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
Basic Settings screen.
• Your ISP allows only one Ethernet MAC address to connect to the Internet and might
check for your computer's MAC address. In this case, do one of the following:
- Inform your ISP that you have bought a new network device, and ask them to use the
wireless modem router's MAC address.
- Configure your wireless modem router to clone your computer's MAC address.
If your wireless modem router can obtain an IP address, but your computer is unable to load
any web pages from the Internet:
• 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 wireless modem
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.
• Your computer might not have the wireless modem router configured as its TCP/IP
gateway.
If your computer obtains its information from the wireless modem 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 wireless modem router. You might
need to go to Internet Explorer and select Tools > Internet Options, click the
Connections tab, and select Never dial a connection.
