OS: windows 7 sp1 , ubuntu 11.04

I have windows 7 pro and ubuntu 11.04 dual
After I installed ubuntu my wifi card (broadcom
bcm 4318 I believe) didn't have the firmware.
Since I don't have a wired connection (I share
with the neighbors) so I pulled out my other
laptop windows7 and downloaded the packages
and installed fwcutter and b43 installer. Well after
that it still didn't work so on a whim I typed "sudo
modprobe b43" and then it worked!
After doing updates and stuff I went to reboot
and then again the wifi wasn't working. Decided
to type "sudo modprobe b43" and it worked
Now everytime I shutdown I have to run that
command and than the wifi works. How can I get
it to work on startup by it self?

You need to append the lines into

Attempted to track down a suspected faulty driver using verifier.exe resulted in multiple BSOD, although only one mini-dump file was successfully written, of the Nvidia system driver nvlddmkm.sys. I was able to deduce this as I had checked each file one by one until BSOD's occurred. However,...
