Edit the Advanced tab ¾ Power Save Mode • Maximum - Selects maximum mode to let the access point buffer incoming messages for the wireless adapter. The adapter will detect the access point if any messages are waiting periodically. • Normal - In Normal mode, the adapter will be switched to maximum mode automatically when no large packets are retrieved. • 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 or 2.4 GHz 11 Mbps 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 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, 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. 15
