Okay. First, what I did after installing Windows 7 on the Sony Vaio SVE15123CDS laptop is I downloaded the network card driver for Windows 7 and then ran Windows Update. Windows Update found all but four drivers. Next, I downloaded and installed a program called DriverEasy. I ran a scan for drivers, and it successfully downloaded and installed three of those missing drivers. It also downloaded and installed the driver for the wireless, but it wasn't the correct one. I actually went to the Sony driver download page for this laptop, and used the Windows 8 wireless driver. It actually worked. Problem solved. Goodbye Windows 8, hello Windows 7.
