Some may still be struggling with getting wireless adapters to work
with even the most current linux distributions. I myself have a dell
Inspiron 1501 with a Broadcom 4312 wireless adapter. Being a novice I
struggled to get my wireless adapter to work for a few days using the
provided drivers, and ndiswrapper, but it did not work. I then came
across the link below, Thanks to Malkor, and following the
instructions I was able to get my wireless drivers working in about 20
minutes without a problem. Please see the link below if you have a
Broadcom Wireless card.
