Sorry, completely forgot about this one...
I would NOT recommend using the fwcutter, it F*CKED my system UP.
Even multiple restarts wouldn't clear whatever it did, i had to reinstall.
BUT, this may have been an isolated incident, who knows...
Ok, what i did was a fresh install of the system.
But if you do the following it might help:
*Uninstall the ndis wrapper that you already tried to install (ndiswrapper -e bcmwl5),
*Go into 'Network' settings and delete any device that says it's wireless (on the FIRST tab, NOT the second one),
*Go into the /etc/modprobe.d/ and add 'blacklist bcm43xx' to both the blacklist docs (not sure if you REALLY need the 2nd one),
*Go into /etc/ and open 'modprobe.config' and remove any line that has 'alias eth1 bcm43xx', or any 'bcm43xx' line at all,
After logging back in:
*First install the ndiswrapper (yum ndiswrapper),
*Then install the driver (ndiswrapper -i /root/Desktop/wherever/the/hell/you/put/this/bcmwl5.inf)
*Terminal-> modprobe ,
*Terminal-> ndiswrapper -m ,
*Terminal-> dmesg to see if it says anything about the device wlan or ndiswrapper (NOT bcm*),
*Then add the wlan/ndiswrapper to 'System->Administration->Network' (leave all options default, you can specify wep keys later),
*Do NOT try to activate it,
*Then edit the device to start when the system starts, and to be able to toggle on and off),
*Save settings and close the window,
*Go to System->Administration->Server Settings->Services,
*Click the boxes to enable the top two options (net NetworkManager, NetworkManagerDispatch),
*Select the first NetworkManager service, click start,
*Do the same thing for the second NetworkManagerDispatch service,
*Go down to the 'Network' service (~= five clicks down on the scroll bar),
*Terminal-> 'dhclient ndiswrapper'
*In the system tray, click on the networkManager,
*Select a wireless network,
*Enter your credentials (correctly; ASCII != HEX || Phrase)
If you can see your wlan device in the modprobe, and have removed the apropriate entries from the apropriate files, and you still don't have a wireless option, reboot.
I had to do alllllllllllllllllllll that ****, and then reboot.
When you're bootin up, at the progress screen hit 'alt + d' for details, and watch what it says when it get's to the 'wlan' part (right after eth0), and if it simply says 'Done', you're good.
If it doesn't say that, i've still had my device work, so i don't completely understand WHY my device is working sometimes, lmmfao, but it does, and i'm just happy that i can remember how to do this after a re-install.
This may not be the best way, but it's what got me working when this tutorial didn't work 100% for me (it's still a good tutorial none-the-less
If i remember anything else relevant to this, i will update accordingly, but remember, if this doesn't work, i am definately NOT the person you want to ask for help, because i've only been using Fedora for about a week now, and i'm even less experienced than you are at it, so i could offer you no help beyond this little bit that i figured out (sorry).
Good luck, i know it was a pain in the ass for me too.
