Newb with wifi problems [Dell Latitude]

[Empire2k5]

Hey, I just installed Linux Mint 9, and this is my first time using Linux. And I'm having some troubles getting the wifi to work. Tried reading other things and those didn't really seem to help. Well my comps a Dell Latitude d531. Not sure what else is needed, but if someone can point me in the right direction or willing to help, I would very much appreciate it. Oh and its a Broadcom BCM4321 if I remember correctly.

If you have a wired connection you should be able to install the driver as so
(from a terminal)

sudo apt-get install bcmwl-kernel-source

There should also be some sort of graphical hardware device manager that can do it for you.

You need to installed the correct WiFi module driver

Reference and download from:
Broadcom.com - 802.11 Linux STA driver

then install packages wpa_supplicant and wireless-tools

after installed the driver and needed software. For example eth1 is your wifi)

step1:
Startup the device eth1
#ifconfig eth1 up

step2:
scan the wifi network need your area, then will show all the information about those searched wifi network. For example, ESSID, CHANNEL, etc
#iwlist eth1 scan

step3:
then you need to login one of wifi network without WPA, no security issue
#iwconfig eth1 essid ssid_name channel which_channel

step4:
if there have no error show, you already connected to the wifi network, but you don't have any IP address to use, so start to get IP address.
#dhclient eth1

if success, IP address was shown. Then you can enjoy your wifi network.
