First check and see if your wireless card is recognized as a wireless card. You can do that by running
iwconfig. It should show your ethernet and lo with "No wireless extensions", but hopefully you have a wlan0 that shows a bunch of information. If your card is not recognized, we need to tackle that before anything else and the way to start would be showing us the output of
lspci -knn|grep -A3 net so we can determine what network devices you have in your system.
If your card is recognized, the most common way to connect to networks is via the included NetworkManager (@repentorperish, rc.wireless.conf use is
deprecated). Wicd is also an option, but you'll need to install it separately. To use NetworkManager, you'll need to make the startup script executable and then start the script. You can do that via the following:
Code:
chmod +x /etc/rc.d/rc.networkmanager
/etc/rc.d/rc.networkmanager start
Once that is done, you should be able to connect to networks via the nm-applet program that is residing in your system tray.
