options you have enabled.
You can then configure:
Operating Mode: The pull-down menu allows you to select and lock the Gateway into the
wireless transmission mode you want. For compatibility with clients using 802.11b (up to
11 Mbps transmission) and 802.11g (up to 20+ Mbps), select
Normal (802.11b + g). To
limit your wireless LAN to one mode or the other, select 802.11b Only, or 802.11g Only.
☛
NOTE:
If you choose to limit the operating mode to 802.11b or 802.11g only, clients
using the mode you excluded will not be able to connect.
Default Channel: 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 activ-
ity 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 SSID as the
client.
AutoChannel Setting: For 802.11G models, AutoChannel is a feature that allows the
Netopia Gateway to determine the best channel to broadcast automatically.
Three settings are available from the pull-down menu: Off-Use default, At Startup, and
Continuous.
• Off-Use default is the default setting; the Netopia Gateway will use the configured
default channel selected from the previous pull-down menu.
• At Startup causes the Netopia Gateway at startup 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-startup scan, and will continuously monitor the current
channel for any other Access Point beacons. If an Access Point beacon is detected on
the same channel, the Netopia Gateway will initiate a three- to four-minute scan of the
channels, locate a better one, and switch. Once it has switched, it will remain on this
channel for at least 30 minutes before switching again if another Access Point is
detected.
