Ok, so I have this sony ultrabook that came with Windows 8. I wasn't ready for the change so I downgraded to Windows 7. The install went fine. But now when I boot I can't detect any wireless networks. I Enabled/Disabled wireless, I tried to install Vaio Smart Network(It won't open) but nothing is working. This is the second clean install I've done. I've tried talking to Sony techs via the online chat but they can't seem to help. They would remote in, look around, try the same things I have and tell me to do another clean install. :/ Anyone have any real answers?
I would compare the wireless LAN driver listed on the support page for Win7 64-bit with what you have installed on your machine. Since the Win8 driver differs from the Win7 driver, it seems like a good place to start.
