It looks like there's a problem with the actual NIC card itself. It's having problems in Windows as well.
So for the past 3 hrs I've been trying to get my broadcom wireless NIC to work. Again, I've run into walls.
Since I have absolutely no internet connection on my laptop I downloaded and burned ndiswrapper-1.3rc1.tar.gz and the 64-bit_Broadcom_54g_Drivers.zip drivers from my desktop onto a CD and put them in my /home directory on my laptop. Then I ran these commands:
tar -xzvf ndiswrapper-1.3rc1.tar.gz
When I use the make command I get the following error:
make -C driver
make: Entering directory '/home/mcrexx/ndiswrapper-1.3rc1/driver'
Can't find kernel sources in /lib/modules/2.6.8-11-amd64-k8/build;
give the path to kernel sources with KSRC=<path> argument to make
make: *** [prereq_check] Error 1
make: Leaving directory '/home/mcrexx/ndiswrapper-1.3rc1/driver/'
make: *** [all] Error 2
Where would I find the kernel sources for ndiswrapper?
