Channel: (1 through 11) on which the network will broadcast. This is a frequency range within the 2.4Ghz 
band. Channel selection depends on government regulated radio frequencies that var y from region to 
region. The widest range available is from 1 to 14. However, in Nor th America only 1 to 11 may be 
selected. Europe, France, Spain and Japan will differ. Channel selection can have a significant impact on 
per formance, depending on other wireless activity close to this Gateway. Channel selection is not 
necessar y at the client computers; the clients will scan the available channels seeking access points using 
the same ESSID as the client.
AutoChannel: (only available for 802.11G models). AutoChannel is a feature that allows the Netopia 
Router to determine the best channel to broadcast automatically.
Three settings are available from the pull-down menu: Off, At Startup, and Continuous.
Off is the default setting; the Netopia Router will use the configured default Channel selected from the 
previous menu.
At Startup causes the Netopia Router at star tup to briefly initialize on the default channel, then per-
form a full two- to three-second scan, and switch to the best channel it can find, remaining on that 
channel until the next reboot.
Continuous per forms the at-star tup scan, and will continuously monitor the current channel for any 
other Access Point activity. If Access Point activity is detected on the same channel, the Netopia 
Router will initiate a scan of the other channels, locate a less active one, and switch. Once it has 
switched, it will remain on this channel for at least 30 minutes before switching again if a new Access 
Point is detected.
Note: Channel scans can be disruptive to normal wireless activity and may take a few minutes.
Closed System: If you toggle Closed System to Closed, the wireless network is hidden from the scanning 
features of wireless client computers. Unless both the wireless clients and the Router share the same 
SSID in Closed System mode, the Router’s wireless LAN will not appear as an available network when 
scanned for by wireless-enabled computers. Members of the Closed System WLAN must log onto the 
Router’s wireless network with the identical SSID as that configured in the router.
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 toggle it to Open, 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.
