So this is my third attempt at 8.1 and second Surface Pro using it because my other just got replaced 3 weeks ago due to dying pixels. I installed the RTM off TechNet yesterday, and still have that intermittent wireless problem. It has happened 3 times now in less than 24 hours. Are you kidding me? How on earth are we this far into 8.1 and they still don't have their flagship $1k tablet's network card working with their own OS? Sorry to rant, but this problem is annoying and the fact that they still haven't fixed it is even more annoying. Be better than this Microsoft.
