I did some research earlier and I found that I might be missing a driver for broadcom called b43-fwcutter. I found directions for how to build fwcutter at linuxwireless because i could not use sudo apt-get to install it. However, even after building it, when everything seemed to go ok without error messages, it would not work even after restarting.

Help?

First check that you have the *.fw firmware files in your /lib/firmware/b43 folder.

If so then can you please post the last few lines of the output from dmesg. Any lines that mention b43, broadcom or wlan0 would be useful.
