Anyone seen the following problem?
I've set it up for WPA-Enterprise (TKIP) and we get all the way through the authentication and the 4-way handshake, and then it sends me a group key which looks like this:
0xaa 0xaa 0x03 0x00 0x00 0x00 0x88 0x8e 0x01 0x03 0x00 0x5f 0xfe 0x03 0x81
0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x05 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x10 0xc3 0xc0
0xb8 0x9e 0x27 0xa3 0x94 0x8f 0x72 0x11 0xa6 0x65 0x46 0xa6 0x94 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xe9
0x0e 0x1d 0xae 0x6b 0x13 0xdb 0x09 0x0f 0x4a 0x0a 0x36 0xfc 0xdc 0xac 0x39
0x00 0x00
which decodes as this:
Version 1, type 3 = EAPOL key, length 0x5F
Descriptor type 0xfe
Key info 0x381:
WPA Key 1/2 -- variant with install for rx only
Descriptor version 1 = no CCMP keys
Key type 0 = not pairwise
Index 0
ACK needed
MIC present
Secure
PTK length 0x0

Key IV 10-c3-c0-b8-9e-27-a3-94-8f-72-11-a6-65-46-a6-94
Received sequence counter 00-00-00-00-00-00-00-00

MIC e9-0e-1d-ae-6b-13-db-09-0f-4a-0a-36-fc-dc-ac-39
Key data length 0x0
Note the total absence of any kind of actual key in this frame.
Shortly afterwards it deauthenticates us for not responding to this non-existent key.
Note, I know this seems like a bug report and perhaps it should be but I can't find anywhere else on this confusing website to mention it. "On-line support" refuses to answer my questions because I'm not a "reseller" and TAC won't accept it because the serial number is not connected with a particular service contract.
*pulls hair out yet again with Cisco's website*
