Not exactly sure where to post this, so I guess I will try to start here. Not a computer wiz either.

I have a Sony Vaio VGN-CS230J notebook and it went down on the 24th of June and is currently still down. Even went to Sony reps for help and none of them really helped me solve anything.

On the day I had lost my internet connection, my notebook kept notifying me every time that I came on that I needed to update my driver software. I tried doing that and nothing worked, even with Sony reps telling me what to do. I even resorted to re-booting the whole thing out of frustration and still nothing.

...Kept telling me my network adapter could not be found, but I believe the PROBLEM lies with my network controller.

If I am not explaining myself clearly enough, someone please do specify for me. Any suggestions are welcomed, because I really want my internet access back.Do you use a cable to connect to the Internet or do you use wireless, with your notebook?

Click on START (the pearl in the bottom left corner of your desktop), TYPE "device manager", when it appears in the menu, click on it.

When device manger opens, observe what does it looks like under "network adapters". Do you see any red X's or yellow exclamation marks?

Make sure your wireless adapter is switched on or your ATTACHED by cable.

Look at the network icon in the notification area
The one on the bottom right of the screen. Its a monitor screen with a big red x on it.

So 'right' click on it

Click on 'diagnose and repair'. Vista should then search for issues and give you some solutions.
