• Off - turns power saving off, thus powering up the wireless adapter continuously
for a short message response time.
¾ 802.11b Preamble - Specifies the preamble setting in 802.11b. The default setting is
Short & Long (access point mode), which allows both short and long headers in the
802.11b frames. The adapter can only use short radio headers if the access point
supports and uses them. Set to Long Only to override allowing short frames.
¾ Wireless Mode - Specifies 2.4 GHz 54 Mbps, 2.4 GHz 11 Mbps, or Super G (Only for
108M Wireless PCI Adapter) operation in an access point network. The wireless
adapter must match the wireless mode of the access point with which it associates
¾ Wireless Mode when Starting an Ad Hoc Network - Specifies Super G (Only for
108M Wireless PCI Adapter) or 2.4 GHz 54/11Mbps to start an Ad Hoc network if no
matching network name is found after scanning all available modes. This mode also
allows the selection of the channel the wireless adapter uses. The channels
available depend on the regulatory domain. If the adapter finds no other ad hoc
adapters, the channel that the adapter starts the ad hoc network with will be selected
automatically. The wireless adapter must match the wireless mode and channel of
the clients it associates.
¾ 802.11 Authentication Mode - Select which mode the wireless adapter uses to
authenticate to an access point:
• Automatic causes the adapter to attempt authentication using shared, but switches it to open
authentication if shared fails.
• Open System enables an adapter to attempt authentication regardless of its WEP settings. It
will only associate with the access point if the WEP keys on both the adapter and the access
point match.
• Shared-key only allows the adapter to associate with access points that have the same WEP
key.
For infrastructure (access point) networks, click Preferred APs… to specify up to four
access points to the client adapter that attempts to be associated to the access points.
