Hello,

I'm trying to get a PSP to connect to my WLAN.  Its a WRT64G v2.0, running WhiteRussian, and using WPA2+AES (wl0_akm=psk2, wl0_crypto=AES).

The PSP gets as far as 'Exchaning key information' but then times out.  Various other devices manage to connect just fine.

In order to try to trace the problem, I equipped myself with another WRT54G, and using kismet-drone and a bit of perl was able to capture and analyse the exchange of authentication packets.

During a successful connections, say from a laptop, there are two Association packets, followed by the four EAPOL Key packets,

Laptop          -> Access Point    -   Association Request
Access Point -> Laptop             -   Association Response
Access Point -> Laptop             -   EAPOL Key 1
Laptop          -> Access Point    -   EAPOL Key 2
Access Point -> Laptop             -   EAPOL Key 3
Laptop          -> Access Point    -   EAPOL Key 4

However, when the PSP tries to connect, things are different.  The association packets are the same, but the EAPOL packets differ.  The Access Point still sends out its first key packet, however the PSP doesn't respond to this, but instead sends out an EAPOL Start packet instead.  Not having had a response, the Access Point repeats its key packets a few times, and then the whole thing times out,

PSP              -> Access Point    -   Association Request
Access Point -> PSP                 -   Association Response
Access Point -> PSP                 -   EAPOL Key 1
PSP              -> Access Point    -   EAPOL Start
Access Point -> PSP                 -   EAPOL Key 1 (Repeat)
Access Point -> PSP                 -   EAPOL Key 1 (Repeat)
Access Point -> PSP                 -   EAPOL Key 1 (Repeat)

What I'm trying to understand is which device at fault.  Is the PSP at fault for failing to the first EAPOL Key packet from the access point, or, is it quite justifiably waiting for some response to its EAPOL Start packet, and the access point is at fault for not supplying it.

As an aside, the I also tried to get it to connect via the second WRT54G (which is running Kamikaze, but configured identically as far as I could manage), but got the same results.

Can anyone offer any advice on where to look next to try to get this working?

Regards,
