Set the Channel.
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 gateway. The default channel is 6.
4. For initial configuration and test, make sure that the Wireless Card Access List is set to
Everyone and that Encryption Strength is set to Disabled.
Note: These settings are not recommended for normal operation, but should be set initially to
test basic wireless connectivity.
5. Click Apply to save your changes.
6. Configure and test your PCs for wireless connectivity.
Program the wireless adapter of your PCs 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 gateway.
Once your PCs have basic wireless connectivity to the gateway, then you can configre the
advanced wireless security functions of the gateway.
Using the Wireless Access by MAC Address Feature
By default, any wireless PC that is configured with the correct SSID will be allowed access to your
network. For increased security, you can restrict access to the wireless network to only allow
specific PCs based on their MAC addresses. You can allow access by:
The Trusted PCs window displays a list of MAC addresses that will be allowed to connect to the
gateway. These PCs must also be configured with SSID and WEP settings which match those of
the DG824M.
Note: If you are configuring the gateway from a wireless PC and you change the
gateway’s SSID, channel, or WEP settings, you will lose your wireless connection when
you click on Apply. You must then change the wireless settings of your PC to match the
gateway’s new settings.
