I am having a IBM Thinkpad R40 notebook. My story is also the same like other. I upgraded to Vista Home Premium and lost the internal drivers. I checked inside Device Manager and found that the network controllers is not installed. I thought everything in the same will be automatic, but the scene was a bit different here. I am not able to find any Vista compatible drivers for it. I need some help to make it work. My wireless and lan both are not working.
