One client works, the other doesn't... both worked before 0.0.3 (auth_frame could not be decrypted)

[Torben Frey]

Hi list,

I have a strange problem using hostap 0.0.3:

after re-installing a Linux Server from scratch and upgrading to hostap 0.0.3 I have the
problem that one Windows client (with another prism card) can still easily connect to the
hostap-machine, the other one (compaq w200 card) cannot.

Both machines were running smoothly with the old hostap (from December I think), the
hardware was unchanged on the server, the software is an upgrade from SuSE 8.0 to SuSE
8.2. The Windows machines were not touched in any way, which shows that WEP-encryption
seems to be working fine for the prism-client machine.

Can anybody help me in finding out why the working machine (prism) produces this in the log:

May 25 22:51:26 server kernel: wlan0: dropped received packet from non-associated STA
xx:xx:xx:xx:67:96 (type=0x02, subtype=0x04)
May 25 22:51:26 server kernel: wlan0: Could not find STA for this TX error
May 25 22:51:28 server kernel: wlan0: xx:xx:xx:xx:67:96 auth_cb - STA authenticated
May 25 22:51:28 server kernel: wlan0: xx:xx:xx:xx:67:96 assoc_cb - STA associated

and the other non working machine (w200) this:

May 25 22:57:34 server kernel: wlan0: handle_authen: auth frame from STA xx:xx:xx:xx:5f:da
could not be decrypted
May 25 23:00:05 server kernel: wlan0: handle_authen: auth frame from STA xx:xx:xx:xx:5f:da
could not be decrypted
May 25 23:03:15 server kernel: wlan0: WEP decryption failed (SA=xx:xx:xx:xx:5f:da)

Any help would really be appreciated!

Thanks a lot,
Torben
