n Power Save Mode: Specify:

ü Maximum mode: causes the access point to buffer incoming messages for

the wireless adapter. The adapter up periodically polls the access point to
see if any messages are waiting.

ü Normal mode: uses maxim when retrieving a large number of packets, then

switches back to power save mode after retrieving the packets.

ü Off: turns power saving off, thus powering up the wireless adapter

continuously for a short message response time.

n Network Type: Specifies the network as either Infrastructure or Ad Hoc.
n 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.

n Wireless Mode: Specifies 5GHz 54Mbps, 2.4GHz 54Mbps, 2.4GHz 11Mbps,

or Super A/G operation in an access point network. The wireless adapter must
match the wireless mode of the access point it associates to.

n Wireless Mode when Starting Ad Hoc Network: Specifies 5GHz 54Mbps,

5GHz 108Mbps, or 2.4GHz 54/11Mbps, to start an Ad Hoc network if no
matching network name is found after scanning all available modes. This
mode also allows 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 with the adapter
starts the Ad Hoc network with. The wireless adapter must match the wireless
mode of the access point it associates to.

n 802.11 Authentication Mode: Select what mode the wireless adapter uses to

authenticate to an access point:

ü Auto: causes the adapter to attempt authentication using shared, but

switches it to open authentication if shared fails.

ü Open: 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.

ü Shared: only allows the adapter to associate with access points that have

the same WEP key.
