Following problems with corrupt system files, and not being a great fan of Vista home edition, I formatted my hard drive and then installed Windows 7 Ultimate. I know it's not supported, but I also know people have done this successfully.
Everything works well except that my machine does not know it has a WLan. Device Manager shows only the ethernet connection under Network Adapters - there is an Unknown Device listed under Other devices.
Simple attempts to run driver updates don't help - not surprising I suppose if it doesn't know what the device is.
Please please can somebody point me at the download I need, and tell me how to install it?
