Next step would be running wpa_supplicant, because my WLAN uses WPA, but:

# wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf

rapidly floods my console with messages

ioctl[SIOCSIWENCODEEXT]: Operation not supported
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

and the syslog with

until I hit ctrl/C.

# dhclient wlan0

just repeats

DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 5

a couple of times with increasing interval values and finally tells me

No DHCPOFFERS received.
No working leases in persistent database - sleeping.

Yeah, looks like it. I posted a report to the project's Sourceforge
"ACX100 USB" forum, too.
