How to Restrict Wireless Access to Your Network

Reference Manual for the ADSL Modem Wireless Router DG834G

4.Set the Region. Select the region in which the wireless interface will operate.

5.Set the Channel. The default channel is 11.

This field determines which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless router or access point. Select a channel that is not being used by any other wireless networks within several hundred feet of your firewall. For more information on the wireless channel frequencies please refer to “Wireless Communications” in Appendix C.

6.For initial configuration and test, leave the Wireless Card Access List set to allow everyone access by making sure that Turn Access Control On is not selected in the Wireless Station Access List. In addition, leave the Encryption Strength set to “Disabled.”

7.Click Apply to save your changes.

Note: If you are configuring the firewall from a wireless computer and you change the firewall’s SSID, channel, or security settings, you will lose your wireless

connection when you click Apply. You must then change the wireless settings of your computer to match the firewall’s new settings.

8.Configure and test your computers for wireless connectivity.

Program the wireless adapter of your computers to have the same SSID and channel that you configured in the router. Check that they have a wireless link and are able to obtain an IP address by DHCP from the firewall.

Once your computers have basic wireless connectivity to the firewall, you can configure the advanced wireless security functions of the firewall.
