Problem with Fedora Core 4, Cisco Aironet 350

Hello!
 
I¡¯m using Fedora Core 4 and Cisco Aironet 350.
I think the FC4 basically support Aironet 350.
So there is eth1 when I typed ¡®iwconfig¡¯ not ¡®ifconfig¡¯.

While building the linux-wlan-ng, it was good.
But after installed the driver, there¡¯s nothing changed.
And if I use the ¡®wlanctl-ng¡¯ command, it always says ¡°Bad Address¡±.
I think, because of the driver already installed, I can¡¯t install ¡®linux-
wlan-ng¡¯ the new wireless driver.
When using ¡°iwconfig eth1 essid XXX¡±, the ping is working.
But wlanctl-ng still says ¡°Bad Address¡±.
What¡¯s the problem?
How can I fix it?
Please Help me.:)
