Appendix A: Troubleshooting
Common Problems and Solutions
Dual-Band Wireless Access Point
If you are having difficulties getting any Internet game, server, or application to function properly, consider
exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an
application requires too many ports or when you are not sure which port services to use. Make sure you disable
all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority over DMZ
hosting. (In other words, data that enters the Router will be checked first by the forwarding settings. If the port
number that the data enters from does not have port forwarding, then the Router will send the data to whichever
PC or network device you set for DMZ hosting.) Follow these steps to set DMZ hosting:
A.Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router. Go to the
Advanced => Port Forwarding tab.
B.Disable or remove the entries you have entered for forwarding. Keep this information in case you want to use it
at a later time.
C.Go to the Setup => Security tab.
D.Select Enable next to DMZ. In the DMZ Host IP Address field, enter the IP address of the computer you want
exposed to the Internet. This will bypass the NAT technology for that computer. Please refer to “Appendix D:
Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.
Once completed with the configuration, click the Apply button.
9. I forgot my password, or the password prompt always appears when I am saving settings to the Router.
Reset the Router to factory default by pressing the Reset button for 10 seconds and then releasing it. If you are
still getting prompted for a password when saving settings, then perform the following steps:
A.Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router. Enter the
default password admin, and click the Security tab.
B.Enter a different password in the Router Password field, and enter the same password in the second field to
confirm the password.
C.Click the Apply button.
10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.
If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for the
Internet connection, the computer does not need any proxy settings to gain access. Please follow these
directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly
to the LAN.
For Microsoft Internet Explorer 5.0 or higher:
A.Click Start, Settings, and Control Panel. Double-click Internet Options.
B.Click the Connections tab.
C.Click the LAN settings button and remove anything that is checked.
D.Click the OK button to go back to the previous screen.
E.Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users.
