As I see this commit is connected with WEP keys only, but yes - it's already included in my driver version.

Well, in the meantime, you can load the module with swcrypto=1, this
will make things work

Sadly not. Same thing with sw and hw crypto.

Even today was using wpa-psk network.. based on some newer wrt54gl linksys
AP - without any serious issues.

This might be because your AP does group key rekeying. I just checked
with a 1250 Cisco AP, group key rekeying works (I configured the AP to
do rekeying every 15 seconds...) This might also be because the AP
implements the rekeying in a funny way (in terms of key indeces), that
iwlwifi doesn't know how to deal with (just thinking aloud).

Please send your wpa_supp conf file over.
Please try to disable the group key rekeying just to see what happens....


AP wireless security tab

	Security Mode:	 	WPA Pre-shared key	
 	WPA Algorithms: 	TKIP (only tkip available)
 	WPA Shared Key:	 	*******
 	Group Key Renewal:      3600 seconds

So there is no option to disable group rekeying.. I can only change it's time - 3600 s is default, and maximum value, 600 is minimum.

wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=adm

ap_scan=1
#fast_reauth=1
#eapol_version=1



network={
#	bssid=00:13:10:4a:c6:88
#	scan_ssid=1
#	proto=WPA
#	key_mgmt=WPA-PSK
#	pairwise=TKIP
#	group=TKIP

	ssid="kretyn.com"
	priority=60
	psk=0000000_made_wtih_wpa_passphrase_and_my_SSID_0000000000
}

With uncommented proto, group and pairwase effect is still the same - no connection.
