WEP and NON WEP option not working

[vcatstester]

Hi all,

There is an option to set your WEP key and have it ‘optional’ so both wep and none WEP equipment can use an access point. I have used this ‘optional’ setting but my equipment with WEP will not connect until I select the ‘Full security’ option, I need to gradually update all the equipment with WEP, until this is does I need the option to use both WEP and none WEP equipment. According to the documentation I have found I have done every thing correctly, problem is it doesn’t work! I have about 30 of these units (1200’s) purchased on the strength they can support both wep and none wep at the same time. Any help would greatly be appreciated here im stuck.

Many thanks Nick

P.S. the current firmware version im using is 12.02T

WEP (Wired Equivalent Privacy)WEP is an 802.11 standard encryption algorithm originally designed to provide your wireless LAN with the same level of privacy available on a wired LAN. However, the basic WEP construction is flawed, and an attacker can compromise the privacy with reasonable effort.

TKIP (Temporal Key Integrity Protocol);TKIP is a suite of algorithms surrounding WEP that is designed to achieve the best possible security on legacy hardware built to run WEP. TKIP adds four enhancements to WEP:

A per-packet key mixing function to defeat weak-key attacks

A new IV sequencing discipline to detect replay attacks

A cryptographic message integrity Check (MIC), called Michael, to detect forgeries such as bit flipping and altering packet source and destination

An extension of IV space, to virtually eliminate the need for re-keying

CKIP (Cisco Key Integrity Protocol)Cisco's WEP key permutation technique based on an early algorithm presented by the IEEE 802.11i security task group.

CMIC (Cisco Message Integrity Check)Like TKIP's Michael, Cisco's message integrity check mechanism is designed to detect forgery attacks.

If VLANs are enabled on your bridges, WEP, MIC, and TKIP are supported only on the native
