According to what you have here the broadcom is your ethernet that is your hardwire not your wireless card your wireless card is listed as a
Intel PRO/Wireless 3945ABG
That card will not work with a Broadcom Driver.

can you list the output of the following terminal commands:
Code: Select all
lspci

Code: Select all
rfkill list all

if the rkkill list all command does not show any hardware is turned off try the following command and see it
wireless will work.
Code: Select all
sudo modprobe iwl3945
dmesg | grep iwl
lspci -nn | grep -i wireless

wireless will work.
Code: Select all
sudo modprobe iwl3945
dmesg | grep iwl
lspci -nn | grep -i wireless


Here you have all the details, i realized with your commentary about the real wireless card. i know the rfkill says that is turned off, but maybe the wireless is broken?

Anyway i tried the last commands about modprobe and lspci -nn here is the result:

[ 14.990158] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, in-tree:s

Thanks a lot for the interest.

Ok the RFkill command shows the card is manually turned off. there must be a hardware switch on the machine most likely a combination of keys f keys etc.

on the other hand the last command show that the correct driver is present and see the card.
So I believe you need to find out where hardware switch is.
What's the make of the machine?
Model # please.
