Thanks bud.
My Samsung 700T is still in warranty so I'll have to wait till December. I agree replacing the card is the best option right now if you can do that as it's not clear if Intel is looking to remedy the issue??? On searching the web Microsoft refer all these issues back to Intel. Samsung is no help and so It's clearly in Intel's court. I have faith we won't be forgotten, but who knows. If not remedied by December the only answer for me is replace the card as a year is a long time to wait for working drivers. The little CNET USB N transceiver is the best option right now. It is reliable and fast.
I do find the original windows drivers stable on N for my Cisco AP so that's a partial win. If you're reading this for the first time read up the thread on for instruction to roll back to the windows 8 original driver. For many this will help depending on your Access Point. If it does not then disable the on board and grab a CNET N transceiver per my earlier notes for quick fix and either wait for a driver that works from Intel or replace the card per above. I also grabbed an Ethernet USB3 NIC for $50 NZ that allows you to plug into a wired network. That's really useful for big downloads if your wireless is unstable. Very hand to have.
Intel, if you do read these notes; in the thread above are details of the problem, an AP model that's affecting me and the events that illustrate the failure of the driver. Good luck.
