Sorry for the delay response my friend, I been really busy over the weekend. So since all of your computers are connected to the internet except for this one, than most likely you'll have to re-install the driver for wireless adaptor on this computer.
ALSO MAKE SURE YOU TURNED THE WIRELESS KEY ON WHICH SHOULD BE NEAR THE KEYBOARD OR IN FRONT OF THE KEYBOARD.
Please go to Device Manager and expand the "Network Adaptors" and take a pic so we know which kind of wireless adaptor you have.
You can also left click the wireless adaptor under network and click "uninstall". Afterwards click on Action on top and click Scan for hardware changes. This will automatically re-install the wireless adaptor for you if you already have the right driver installed in the first place. If you don't than I can find the driver for as long as you send me the pic of the Device Manager.
Did you read my last post , I was able to get it connected with the LAN cable, but wireless is still not working . UsernameIssues is helping me with the current situation.
