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 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 or 2.4 GHz 54/11

Mbps 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, this selection specifies which channel the adapter starts the ad hoc network

with. 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.
