N150 Wireless Router User Manual
•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 will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the wireless router’s configuration, restart your computer. Alternatively, you can configure your computer manually with a DNS address, as explained in the documentation for your computer.
•Your computer might not have the wireless router configured as its default gateway. Reboot the computer and verify that the wireless router address (www.routerlogin.net) is listed by your computer as the default 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.
If the wireless router does not save changes you have made in the browser interface, check the following:
•When entering configuration settings, be sure to click Apply before moving to another screen or tab, or your changes could be lost.
•Click Refresh or Reload in the Web browser. The changes might have occurred, but the Web browser might be caching the old configuration.
