MacBook – Windows 8 RP says no network adapter found under boot camp in the new Retina MBP. Can anyone help me get the driver for the network adapter

Your MacBook has a AMD Radeon HD 6490M video card per your properties screen. You'll need to download the driver from AMD's website.

For Windows 7:

• 32 bit: http://support.amd.com/us/gpudownload/windows/Pages/radeonmob_win7-32.aspx

For your display driver you might need to update your Bootcamp drivers which you can get from Apple's Boot Camp Support Drivers.

Apparently the problem is that the "Apple Broadcom Built-in Bluetooth" driver is not the right one for the new hardware. Here's what I did to fix it:

• Open Device Manager, open the Bluetooth Radios subtree, right-click the "Apple Broadcom Built-in Bluetooth" icon, and choose the "Update Driver Software..." menu item.
• Choose "Browse my computer for driver software"
• Choose "Let me pick from a list of device drivers on my computer"
• Select "Apple Inc." for Manufacturer, and "Apple Built-in Bluetooth" for Model, and click Next.

After the driver installed, "Apple Broadcom Built-in Bluetooth" had been replaced by "Apple Built-in Bluetooth" and "Microsoft Bluetooth Enumerator" in the Bluetooth Radios subtree of Device Manager, and I was then able to use the Add a device wizard to set up my Bluetooth mouse and keyboard.
