Wireless-G Router for Mobile Broadband
6. Check the Enable option for the port services you want to use. Consider the example below:
When you have completed the configuration, click the Save Settings button.
8. I can’t get the Internet game, server, or application to work.
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:
1. 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 Applications & Gaming => Port Range Forward tab.
2. Disable or remove the entries you have entered for forwarding. Keep this information in case you
want to use it at a later time.
3. Go to the Applications & Gaming => DMZ tab.
4. Select Enable next to DMZ. In the Client PC 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 E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting
an IP address.
5. Once completed with the configuration, click the Save Settings 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:
