axisaudio

I tried to get my wireless running in FC6 by following the wireless instructions here and I got the following in my terminal

[root@localhost ~]# ndiswrapper -i /axisaudio/bcmwl5.inf
driver bcmwl5 is already installed
[root@localhost ~]# ndiswrapper -m
adding "alias wlan0 ndiswrapper" to /etc/modprobe.d/ndiswrapper ...
couldn't add module alias: at /usr/sbin/ndiswrapper line 705.
[root@localhost ~]# modprobe ndiswrapper
FATAL: Module ndiswrapper not found.

I am using a BCM4306 802.11 b/g wireless card, and my laptop is a dell inspiron 1150. Replies to this fix would be appreciated
