RE: malformed EAPOL-Key with LEAP and AEGIS Client
Hi Artur, Thanks for the info about the EAPOL packets. I've installed the latest drivers both for the AP and the pcmcia card. It seems that the AP340 has a bug(?:( Is there any website of Cisco where I can post my question?

RE: malformed EAPOL-Key with LEAP and AEGIS Client
Artur, Have you checked if the last EAPOL-Key is malformed. It works fine for me too even if the packet is not correct !! I tried to pass traffic with WEP enabled and I didn't have any problem, but I don't know if this packet should be malformed anyway!! Could you please try to pass traffic using LEAP method and WEP enabled? I would love to send me an ethereal sniff !

malformed EAPOL-Key with LEAP and AEGIS Client
Hi All, I'm using WEP enabled mode where I get 2 EAPOL-Keys with the second malformed from the AP-340 !!! I use also AEGIS client in Windows XP Home. I've attached the ethereal dumps to check what exactly I mean. I don't know if it is a bug in the AP or the freeradius, but I suspect that the freeradius doesn't construct well the second EAPOL-Key message and the AP forwards a malformed packet.
