Mm, see below. Don't know exactly what you mean :)

WLA-G54 Ver.2.05, the latest available as of January 19th 2004

Sure, I should have sent it in the first place :)
Here it is, but note that I've tried almost every combination that I've
found in the docs and howto's, etc:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=0
network={
	scan_ssid=1
	proto=WPA
	key_mgmt=WPA-PSK
	ssid="WIDEXS"
#	pairwise=TKIP
	psk="widexslan001"
	priority=5
}

Maybe this is a config that shouldn't work, but it just doesn't 
make a difference with whatever I configure in key_mgmt, pairwise, etc.

Mm, I see. The config-page for the Wireless LAN Security looks like this:

Version 0.2.4

Thanks for your time :)
