TIP: USB 3 Ethernet gets around Thunderbolt problem with Windows Boot Camp

Two readers report no success with previous suggestions about problems with Thunderbolt Ethernet adapters running under Windows on a Mac using Boot Camp. One reader provided additional information, while Kim Bliss got around the problem by using a USB 3.0 adapter instead of Apple's Thunderbolt adapter:

I also had a problem with my Thunderbolt adapter when using Boot Camp and Windows 8.1 and I looked at the [Fast Startup] setting that you mentioned but it was already unchecked. Due to the adapter problem, I was not able to connect to my external drive and couldn't access my file server from Windows.

Shut down and start up did not work either. What did end up working was this suggestion provided by Intel tech support: purchase a 3rd party USB 3 adapter instead of using something that is made for OS X or Windows because the 3rd party adapters are usually made to work with either. The Cable Matters 3.0 USB to Gigabit Ethernet adapter works fine with either operating system. I have not figured out how to use the Thunderbolt with Windows but at least I have a working adapter for Windows now.

If you've got Ethernet working with a USB adapter in Boot Camp, .

(Amazon offers the Cable Matters USB 3.0 to Gigabit Ethernet Adapter for $20.)

Arthur also has the problem, and tried different versions of network drivers and Boot Camp, to no avail:

Yep, this exact issue as been hounding me for since I bought the very first released Macbook Pro 15" Retina. It happens regardless of the network driver installed (, 15.6.13 or It happens regardless of the Boot Camp 5 version (5.0.5033, 5.1.5621, 5.1.5640).

Nothing helped. The wired Thunderbolt network drops intermittently - I can't seem to detect a pattern. The wireless network appears to work just fine

I am running Windows 8.1 Update 1 (just released the other day on Tuesday) and it's still happening.

BTW, Apple's OS X has been completely removed. Let's say I am a .NET developer who likes the best hardware.

Do you have anything to add to this discussion? Please .
