Today the network adapter that was only designed to work in Surface Pro and Surface Pro 2, now works in Surface RT too. This is because Microsoft has quietly added the necessary networking drivers to support the Ethernet adapter accessory in Windows RT 8.1.
This is a great news for Surface owners who need to connect to a network and a wireless access-point isn’t an option. Keep in mind that Microsoft won’t be making available the driver available for download on Windows RT 8.0, you must update to Windows RT 8.1. Update: Use this guide, if you experiencing problems or you get the message “Not Compatible with this version of Windows” trying to install the Surface Ethernet adapter in your RT device.
