Dropping EAPOL frame, not key frame
We have wireless clients doing MS-CHAPv2 authentication against our access points. FreeRADIUS serves as a proxy between the APs and our domain controllers. When a Mac laptop connects, or in some cases roams, we see the wifi icon laddering up and down for 20-30 seconds. During this time, I've spotted the following error in the laptop's system.log: inputEAPOLFrame: Dropping EAPOL frame, not key frame Initial Googling hasn't turned up anything relevant, and I realize this is likely not a FreeRADIUS issue (as it's only a proxy). But I'm hoping that the collective wisdom of FreeRADIUS users could shed some light on what's going on. I'm comfortable wiresharking this to death, but my EAP knowledge is somewhat anemic. Can anyone shed some light on what's going on here? Thanks, Norman Elton

EAPoL is EAP over LAN. It's the communication protocol between the laptop and the access point. i.e. it has nothing to do with RADIUS.

It isn't a RADIUS issue. My guess is that the access point is broken. Switch it out for another one, and the messages will disappear. Don't use the same make / model. Switch vendors. Alan DeKok.
