I have a Sony Laptop (VGN-NW 150J). In Device Manager under UNKNOWN DEVICES it has "network conntroller". I looked up the numbers for the unknown device identifier 7.0 program and I have never used this version of unknown device identifier before. The numbers are ven-8086n and Dev-4232. I don''t know what to do from there. Could someone please tell me how to find what driver to download to get the wireless network card to work?
