Hi guys, felt I had to share this: anyone wondered why WLC uses 104 bits and Autonomous uses 128 bits ?
Well I have and it´s been bugging me in the background cause I didn´t know why this difference was, even though stuff was working as expected with same passwords e.t.c. But glazing through this TAC collection is both fun and gives you some flashbacks to stuff that one has experienced in the past. I am for sure going to explore this option some more and read more from that collection. So this gave me the explaination: Solution # K23942005 Title User receives the "128bit isn't supported on the Access point" error message during the configuration of the WEP on the WLC Core Issue This error message appears when 128-bit encryption is used in place of the 104-bit encryption. Resolution This 128bit isn't supported on the Access point error message is seen on controllers when the key lengths shown are actually the number of bits that are in the shared secret and do not include the 24-bits of the IV. Many products, which includes the Aironet products, mention a 128-bit WEP key when in reality, it is a 104-bit key with 24-bit IV. On the controller, the key size of 104-bit is 128-bit. The 128-bit key size on the controller is actually a 152-bit key. So in order to set the 128-bit key, set with the 104-bit.
