Maximum mode causes the access point to buffer incoming messages
for the wireless adapter. The adapter periodically polls the access
point to see if any messages are waiting.
Normal uses maximum when retrieving a large number of packets,
then switches back to power save mode after retrieving the packets.
Off turns power saving off, thus powering up the wireless adapter
continuously for a short message response time.
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.
Auto causes the adapter to attempt authentication using shared, but
switches it to open authentication if shared fails.
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.
Shared only allows the adapter to associate with access points that
have the same WEP key.
For infrastructure (access point) networks, click the Preferred APs button to specify up to
four access points to which the adapter should attempt to associate.

Additional Security Features
ar5211.sys
from the folder
These security features prevent attacks on a wireless network's WEP keys. The wireless
adapter automatically supports each of these features, but these features must be enabled
on the access point.
Message Integrity Check (MIC)
MIC prevents bit-flip attacks on encrypted packets. In a bit-flip attack, someone
intercepts an encrypted message retransmits it after some alterations. Thus the receiver

Key Integrity Protocol (TKIP)
This feature prevents attacks on WEP in which someone catches encrypted packets and
uses their initialization vector (IV) to decipher the WEP key. TKIP removes the
predictability to protect both unicast and broadcast WEP keys.
Key Rotation
EAP authentication provides dynamic unicast WEP keys for wireless adapters, but uses
static broadcast keys. In broadcast WEP key rotation, the access point supplies a
dynamic broadcast WEP key and changes it at intervals.
