Here is more data on my problem with dynamic wep. compat-wireless-2008-05-07 + iwl4965 + swcrypto=1: Associates and obtains dhcp lease, works fine. So it really is about the HW accelleration. I tried your patch (without swcrypto=1). First, output of wpa_supplicant: EAPOL: Received EAPOL-Key frame EAPOL: KEY_RX entering state KEY_RECEIVE EAPOL: processKey EAPOL: RX IEEE 802.1X ver=1 type=3 len=57 EAPOL-Key: type=1 key_length=13 key_index=0x1 EAPOL: Successfully fetched key (len=64) EAPOL: EAPOL-Key key signature verified EAPOL: Decrypted(RC4) key - hexdump(len=13): [REMOVED] EAPOL: Setting dynamic WEP key: broadcast keyidx 1 len 13 wpa_driver_wext_set_key: alg=1 key_idx=1 set_tx=0 seq_len=0 key_len=13 RX EAPOL from 00:13:c4:8a:be:30 RX EAPOL - hexdump(len=48): 01 03 00 2c 01 00 0d 00 00 48 23 40 de a7 a8 0e 57 ec cc b4 2e c4 58 30 18 51 11 55 a0 9d 5f 83 77 f4 ef ca 46 09 02 4b d4 1a 01 84 47 03 41 80 EAPOL: Received EAPOL-Key frame EAPOL: KEY_RX entering state KEY_RECEIVE EAPOL: processKey EAPOL: RX IEEE 802.1X ver=1 type=3 len=44 EAPOL-Key: type=1 key_length=13 key_index=0x83 EAPOL: Successfully fetched key (len=64) EAPOL: EAPOL-Key key signature verified EAPOL: using part of EAP keying material data encryption key - hexdump(len=13): [REMOVED] EAPOL: Setting dynamic WEP key: unicast keyidx 3 len 13 wpa_driver_wext_set_key: alg=1 key_idx=3 set_tx=128 seq_len=0 key_len=13 EAPOL: all required EAPOL-Key frames received WPA: EAPOL processing complete Cancelling scan request Cancelling authentication timeout State: ASSOCIATED -> COMPLETED CTRL-EVENT-CONNECTED - Connection to 00:13:c4:8a:be:30 completed (auth) [id=0 id_str=] Your patch yields: May 8 14:03:54 localhost kernel: iwl4965: enable hwcrypto key sta=31 alg=0,keyid=1 static_key=1 May 8 14:03:54 localhost kernel: iwl4965: enable hwcrypto key sta=0 alg=0,keyid=3 static_key=0 Should static_key not be the other way round (key_idx 3 is unicast)? In any case, after a while the broadcast key gets updated: wpa_supplicant says EAPOL: Received EAPOL-Key frame EAPOL: KEY_RX entering state KEY_RECEIVE EAPOL: processKey EAPOL: RX IEEE 802.1X ver=1 type=3 len=57 EAPOL-Key: type=1 key_length=13 key_index=0x2 EAPOL: Successfully fetched key (len=64) EAPOL: EAPOL-Key key signature verified EAPOL: Decrypted(RC4) key - hexdump(len=13): [REMOVED] EAPOL: Setting dynamic WEP key: broadcast keyidx 2 len 13 wpa_driver_wext_set_key: alg=1 key_idx=2 set_tx=0 seq_len=0 key_len=13 EAPOL: all required EAPOL-Key frames received WPA: EAPOL processing complete and the syslog contains May 8 14:05:10 localhost kernel: iwl4965: enable hwcrypto key sta=31 alg=0,keyid=2 static_key=0 5 minutes later the next cycle: EAPOL: Received EAPOL-Key frame EAPOL: KEY_RX entering state KEY_RECEIVE EAPOL: processKey EAPOL: RX IEEE 802.1X ver=1 type=3 len=57 EAPOL-Key: type=1 key_length=13 key_index=0x1 EAPOL: Successfully fetched key (len=64) EAPOL: EAPOL-Key key signature verified EAPOL: Decrypted(RC4) key - hexdump(len=13): [REMOVED] EAPOL: Setting dynamic WEP key: broadcast keyidx 1 len 13 wpa_driver_wext_set_key: alg=1 key_idx=1 set_tx=0 seq_len=0 key_len=13 EAPOL: all required EAPOL-Key frames received WPA: EAPOL processing complete Cancelling scan request May 8 14:10:30 localhost kernel: iwl4965: disable hwcrypto key sta=31 alg=0,keyid=1 static_key=1 May 8 14:10:30 localhost kernel: iwl4965: enable hwcrypto key sta=31 alg=0,keyid=1 static_key=0 and so on... I never acquire a dhcp lease, dhclient always times out. As an aside, I just got an atheros-based pcmcia card for testing purposes and maybe sniff if necessary (though haven't done that yet). Result so far: 1) compat-wireless-2008-05-07 + ath5k: Fails to associate with AP. 2) madwifi: associates and obtains dhcp lease, works perfectly.
