Connect to the internet with a cable.
Use the ubuntuforums, here, and google.com to search.

You will need to type
Code:
 ifconfig -a
to see which interface is active.
Code:
dmesg | grep ethX <X being the non active NIC>
ifconfig ethX up
iwconfig ethX essid any

You also will need to look at the specs to be able see which wireless driver you need.
Have you installed wireless tools?

I would take it in a slightly different order:

First: "iwconfig" (In Ubuntu, probablyl "sudo iwconfig"
This tells you if you have a working wireless device.....If all the devices say "no wireless extensions", then you need to install a driver. For this, we need the specs on your wireless card. Probably the easiest way to find this is "lspci"

The commands in quotes are entered in a terminal. If you haven't found this already, look through your menus.

We definitely need more information. Open a terminal.

Type in the following and post the output of each.
Code:
lspci | grep -i net
lsmod
dmesg | grep firmware

please post the output to:
Code:
lspci # will tell us the pci devices you have in your system.
lsusb # will tell us the usb devices you have in your system.
ifconfig # will tell us what network interface cards that are turned on you have on your system.
ifconfig -a # will list all network interface cards you have on your 
iwconfig # will tell us which of your network interface cards has wireless capability 
lsmod # will list the modules that are loaded on your system.

sudo iwlist <network-card> scan # this will use the <network-card> interface (that from the iwconfig command above) and scan for wireless routers that are accessible.
sudo iwconfig <network-card> essid <your-router-name> # assuming no security (the access point names will be provided by the previous iwlist command).
sudo dhclient # will attempt to get ip-address, subnet mask, dns server information automatically from your router assuming dhcp is turned on on your router.
it would be easier for us to read if it is in [code] tags.
