• Message Integrity Check (MIC)—MIC is an additional WEP security feature that prevents attacks
on encrypted packets called bit-flip attacks. The MIC, implemented on both the AP and all
associated client devices, adds a few bytes to each packet to make the packets tamper-proof.
• Temporal Key Integrity Protocol (TKIP)—TKIP, also known as WEP key hashing, is an additional
WEP security feature that defends against an attack on WEP in which the intruder uses an
unencrypted segment called the initialization vector (IV) in encrypted packets to calculate the WEP
key.
• Repeater mode—Aironet extensions must be enabled on repeater access points and on the root
access points to which they associate.
• World mode—Client devices with world mode enabled receive carrier set information from the AP
and adjust their settings automatically.
• Limiting the power level on associated client devices—When a client device associates to the access
point, the AP sends the maximum allowed power level setting to the client.
Disabling Aironet extensions disables the features listed above, but it sometimes improves the ability of
non-Cisco client devices to associate to the access point.
