FC4 安装无线网卡的问题

shychen

用ndiswrapper 1.7 安装了Realteck 8180L芯片的无线网卡. 用ndiswrapper -l 可以看见net8180 dirver present hardware present. ; 用dmesg | grep "ndiswrapper" 也可以看见相关信息.
但是当我试图用iwconfig 去配置wlan0时,出现如下警告:

Warning: Driver for device wlan0 recommend version 18 of Wireless Extension,
but has been compiled with version 17, therefore some driver features
may not be available...

用iwlist wlan0 scan 可以找到 AP, 但是无法配置和激活无线网卡

请高手指点一二

本本的配置是IBM Thinkpad R40e P4 2.0 M 256Ram, 30GHDD, Netgear MA521 无线网卡
OS: FC4 2.6.11-1.1369
