Hi Tino2fasT,  The following WLAN cards are offered on this system: In order to install the correct driver for the wireless card, you would need to check the wireless card installed on your computer. You can check it from system configuration tab on support website.  You can also check the system configuration from the link: [URL] and then install the appropriate drivers from link: [URL]   If you are not able to find the wireless card installed on your computer, you can private message me the service tag. I have added you as a friend. Please accept my friend request by clicking on my name highlighted in blue and then click on “Friends” tab at the top and then click on “Request to Review” and finally click on “Accept” button. I am sending you a private message as well. Click on “Inbox” to respond to the message and provide system’s Service Tag and contact details so I may access your system records and check for further course of action. You could also click on Start Conversation to send a private message. Please share the findings. 
Ok.. I was given a Dell Inspiron Duo 1090 by a good friend. It had Windows 7 home when i got it. I had already updated a previous computer of mine to Windows 7 Ultimate so I decided that I would update this one as well since I had spent $319.00 for the Operating System, lol. Well, after the install I cannot for the life of me find the "Network Controller" Driver... not even a generic one... ANY help would be GREATLY appreciated!!!
