It came with Windows 7 Starter on it and I just upgraded to Ultimate. Both 32bit. I know it's a Broadcom card, but I'm not sure how to find the model number (I'll post it if someone can tell me how). I have been searching for the drivers for hours and nothing has worked.
First place I went was to Lenovo's support site and they didn't work. There was also two links that gave the same file by accident (maybe that's the one I need). I then tried about 20 more and still no luck. I am dual booting it with Ubuntu and it automatically prompted me to download the un-approved driver. Then it worked.
Has anyone else had this problem with Windows 7? This netbook is essentially useless to me if the Wi-Fi doesn't work.
