wpa_supplicant 0.2.5: succesful key negotiation, kicked off by "new AP" event

Hello,

I'm using wpa_supplicant 0.2.5 along with Intel ipw2100 drivers (version 1.0) on a linux 2.6.9 kernel on a Gentoo distribution. This against a Buffalo AirStation G54 access point, using a WPA-PSK configuration with AES encryption.

As what i understand from wpa_supplicant debugging output (which i can send directly to anybody willing to help me), wpa_supplicant succesfully finds the wireless LAN and performs the key negotiation:

WPA: Key negotiation completed with 00:07:40:a2:d4:98
Cancelling authentication timeout
EAPOL: External notification - portValid=1
EAPOL: External notification - EAP success=1

immediately after, though, a wireless event is received:

Wireless event: cmd=0x8b15 len=20
Wireless event: new AP: 00:07:40:a2:d4:98

("new AP", maybe still scanning?). In consequence, negotiated keys are cleared and process is kicked off again:

Association event - clear replay counter
Associated to a new BSS: BSSID=00:07:40:a2:d4:98
wpa_driver_ipw2100_set_key: alg=none key_idx=0 set_tx=0 seq_len=0 key_len=0
wpa_driver_ipw2100_set_key: alg=none key_idx=1 set_tx=0 seq_len=0 key_len=0
wpa_driver_ipw2100_set_key: alg=none key_idx=2 set_tx=0 seq_len=0 key_len=0
wpa_driver_ipw2100_set_key: alg=none key_idx=3 set_tx=0 seq_len=0 key_len=0
wpa_driver_ipw2100_set_key: alg=none key_idx=0 set_tx=0 seq_len=0 key_len=0
EAPOL: External notification - portValid=0
EAPOL: External notification - EAP success=0
EAPOL: External notification - portEnabled=1
EAPOL: SUPP_PAE entering state CONNECTING

result is that i never get a stable connection. Any clues about what to do with this problem, please?

kind regards

David Losada
