Where are you getting these instructions that are always telling you to delete a bunch of files?
Maybe the documentation in /usr/share/ would be a better choice!
Check if your bcm43-fwcutter package supplies a script to download a driver that works and cut out the firmware for you.
When I installed FC10 on my old laptop, I grabbed the script from a SuSE rpm package, and ran it.
The wireless device was working in seconds.
You can use `mc' to extract a file from an rpm package. The script may be generic enough to work on any distro. Make sure that you download the package for the correct architecture, e.g. x86_64 for a 64 bit x86. In the least you can read the two links that are used to download the drivers. They are from the openwrt site.
A good place to locate rpms is http://rpm.pbone.net
. You can filter by distro and version. A recent version of bc43-fwcutter would be better in case the urls in the script have changed.
