EW-7608Pg pci on Ubuntu 11.10 - no wireless connection.

[ksht]

A freshly installed Ubuntu 11.10 on my desktop - everything seems to work just fine except the wireless Internet connection. Unfortunately, I can't connect a usual wired cable due to the remote computer location. I have Edimax PCI EW-7608Pg wireless card on my computer. I am relatively new to -nixes but it seems the problem is the system just doesn't recognize the card.
After executing this terminal command [sudo lshw -C network] I obtained the following:
kshtwohn@kshtwohn-desktop:~$ sudo lshw -C network
[sudo] password for kshtwohn:

so as far as I can see the system was able to recognize my Ethernet port only. Then I went to the website of Edimax just to find out that they suggest a Linux driver for my card with .tar.gz extension. I have no idea now what should I do - I don't even know how to install this .tar.gz driver, if needed. Please, help.
