Note
Note
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. To use MIC, client adapters must use one of the following
driver versions, and MIC must be enabled on the access point:
• PCM/LMC/PCI card driver version 8.01 or greater
• Mini PCI card driver version 2.20 or greater
• PC-Cardbus card driver version 3.4 or greater.

Viewing the Current Status of Your Client Adapter
The current profile may be different than the default profile if
you are using auto profile selection. The client adapter does not
switch profiles as long as it remains associated to the access
point or reassociates within 10 seconds (or within the time
specified by the LEAP authentication timeout value if LEAP is
enabled). Refer to Chapter 4
using profiles.
If your current profile becomes disabled due to an invalid LEAP
username and password, this field lists the profile as (Disabled).
Auto profile selection is supported in PCM/LMC/PCI card
driver version 8.01 or greater, mini PCI card driver version 2.20
or greater, and PC-Cardbus card driver version 3.4 or greater.
Yes or No
This setting appears only for 2.4-GHz client adapters.
Refer to the Use Short Radio Headers parameter in
for information on using short radio headers.
If the access point is using MIC, your client adapter's driver
must support MIC; otherwise, the client is unable to associate.
