Closed System mode is an ideal way to increase wireless security and to prevent casual
detection by unwanted neighbors, office users, or malicious users such as hackers.
If you do not enable Closed System Mode, it is more convenient, but potentially less
secure, for clients to access your WLAN by scanning available access points. You must
decide based on your own network requirements.
About Closed System Mode and Wireless Encryption
Enabling Closed System Mode on your wireless Router provides another level of security,
since your wireless LAN will no longer appear as an available access point to client PCs
that are casually scanning for one.
Your own wireless network clients, however, must log into the wireless LAN by using the
exact SSID of the Motorola Netopia® Router.
In addition, if you have enabled WEP or WPA encryption on the Motorola Netopia® Router,
your network clients must also have WEP or WPA encryption enabled, and must have the
same WEP or WPA encryption key as the Motorola Netopia® Router.
Once the Motorola Netopia® Gateway is located by a client computer, by setting the client
to a matching SSID, the client can connect immediately if WEP or WPA is not enabled. If
WEP or WPA is enabled then the client must also have WEP or WPA enabled and a matching
WEP or WPA key.
Wireless client cards from different manufacturers and different operating systems accom-
plish connecting to a wireless LAN and enabling WEP or WPA in a variety of ways. Consult
the documentation for your particular wireless card and/or operating system.
Block Wireless Bridging
Check the checkbox to block wireless clients from communicating with other wireless cli-
ents on the LAN side of the Gateway.
