Advanced Client Adapter Status (continued)
Description
Specifies whether the client adapter must share the same WEP keys as
the access point in order to authenticate or can authenticate to the
access point regardless of its WEP settings.
Value: Open or Shared
An incorrect WEP key setting prevents connectivity to the
Note
network regardless of the 802.11 authentication type selected.
Refer to the
Note
information on setting the 802.11 authentication mode.
Indicates whether your client adapter is using message integrity check
(MIC) to protect packets sent to and received from the access point.
MIC prevents bit-flip attacks on encrypted packets. During a bit-flip
attack, an intruder intercepts an encrypted message, alters it slightly,
and retransmits it, and the receiver accepts the retransmitted message
as legitimate.
Note
MIC is supported automatically by the client adapter's driver,
but it must be enabled on the access point.
Value: None, MMH, or Michael
Message Integrity Check
None
MMH
Michael
The type of quality of service that is currently being used by your client
adapter. QoS on wireless LANs (WLAN) provides prioritization of
traffic from the access point over the WLAN based on traffic
classification.
Value:
None or WMM
QoS
None
WMM
WMM is supported automatically in the client adapter
Note
software. However, you must enable the Windows QoS Packet
Scheduler to ensure WMM support. Follow the instructions in
the
QoS Packet Scheduler.
