N750 Wireless Dual Band Gigabit Router WNDR4000 User Manual

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.

• Your computer might not have the router configured as its TCP/IP gateway.

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.

Changes Not Saved

If the wireless router does not save the changes you make in the wireless router interface,

check the following:

• When entering configuration settings, always click the Apply button before moving to

another screen or tab, or your changes are lost.

• Click the Refresh or Reload button in the Web browser. The changes might have

occurred, but the old settings might be in the Web browser’s cache.

Incorrect Date or Time

Select Security > Schedule to display the current date and time. The wireless router uses the

Network Time Protocol (NTP) to obtain the current time from one of several network time

servers on the Internet. Each entry in the log is stamped with the date and time of day.

Problems with the date and time function can include the following:

• Date shown is January 1, 2000. This means the wireless router has not yet successfully

reached a network time server. Check that your Internet access is configured correctly. If

you have just finished setting up the wireless router, wait at least 5 minutes, and check

the date and time again.

• Time is off by one hour. The wireless router does not automatically sense daylight savings

time. In the Schedule screen, select the Automatically adjust for daylight savings time

check box.
