Download the wifi drivers from here https://drive.google.com/file/d/0B4EXB7Ngka9pRmlwX3NFLVZaa00/view?usp=sharing, uninstall the current wifi drivers and then the drivers again. You need to right click on SDIO adapter, go to properties and uninstall the drivers, make sure your select the option for ‘delete the driver software from this device”. Then open the folder with the wifi drivers, right click on install.cmd, select ‘run as administrator’. Then it should work.
This will give you the latest graphics drivers, the installation takes a long time, maybe 5-8 mins, if that doesn’t work then I can upload the drives for to later tonight.
I think that’s why you are having issues. The version that works fine is build 10240 (type “winver” in search bar). The same version that came with the tablet. The new build you have doesn’t work well with current intel drivers.
What build of Windows do you have installed? I upgraded to the new build from Windows update and had some major issues with sleep and power management. Using the previous build now and everything is fine.
