After reading the perfect thread at www.gidforums.com and couple of hundreds other pages I thought I will create more details and spicefic tutoial for FC5 and Belkin wireless cards. This tutorial take in consideration that you may missed up the installion before ,so we going to try also to clean the miss first. We will use ndiswrapper for our driver as this utility able to use to the native windows driver for the card. I'm not an expert by any means in this subject ,so if you think a step wasn't that important you may skip it. My system is FC5 and this tutorial will focus on it only. OK enough talking and lets get busy!

First of all , you will need to follow the steps :

2.Create a folder called wireless.
3.You need to update your kernel.
4.You need to download the source code for the new kernel.(now you have a perfect match bin 2 src)

6.If you have previous installation of ndiswrapper, please do this:
7.Then if this result any output like the above do this(you should do it any way):
this will remove the added drive to the ndiswrapper & remove the ndiswrapper from linux.
8.You need to remove all the previous attempted you made to install the card, in the ndiswrapper folder do this: 9.now we need to find the other files and delete this :
now delete every file from the output ,in my case the file is located at:
now delete the rest :

10.Ok , now you need to add this to the blocklist:
add “blacklist bcm43xx”
save this file & exit.
11.Reboot.
12.Now install the ndiswrapper again:
13.By now we are ready to install the driver:
14.check
15.done ? not so soon
At this point your card should light up, if not you have a problem some where.
16.Now let configure this in the GUI environment ,
1.System->Administration->Network
2.New->wireless connection->Forward (button)->”Broadcom Corporation BCM4318 [AirForce One 54g]”
3.complete the wizard and finish it .
4.If you are using secure connection add the key ,remember to add 0x for your hex key.
5.No click on activate.
17.We are done ,last thing to add this “modprobe ndiswrapper” to the startup. So edit the
18.Reboot.
19.Done!.
