Go to Solutionvenue 8 pro WiFi Issues - After Windows Update - DON NOT INSTALL KB2903939
Last night when running windows update I noticed that one of the updates caused my WiFi to fail. My tablet wouldn't let me enable my Wifi card. I had to recover my comptuer quite a few times to finally find out what update was causing the problem.
KB2903939 from Windows update was the cause for my headaches! fortunatley you are able to uninstal it.
If you are having this issues you can always uninstall it and it will restore your wifi.
DO NOT install the Dec update, caused the wireless to disconnect on my venue pro 8. Tried uninstalling KB2903939 but that didn't help. Had to reset it back to factory settings.
Btw, I noticed my tablet keeps crashing as well. Noticed a weird bugcheck code of 0x0000014f in event log and a couple errors that seems to suggest touch screen issue but this only happened after the Dec update. Before that it was working flawlessly.
I can confirm similar issues.
Purchased my Venue 8 Pro yesterday. Ran through setting up all my stuff. This morning I did Windows Update which installed many items including KB2903939 and two problems started: 1) WIFI is showing disabled, I try to enable it, does not work. Device manager looks fine. 2) When the device goes to sleep, it powers off.Can't say if it's this particular KB as about 15 updates were installed today.
Anyone have additional details about this?

Known issue
We are working with the driver manufacturer to resolve this issue. For now, Windows Update does not offer this update for computers that have certain drivers installed (including Rtbth.sys and Netr28x.sys).

I wonder if this is an MS issue or Qualcomm issue.
I also had problem on one pc with KB2903939 - please see my post at Windows 8 Forums -
Evidently some people are having problems with this update, some are not. I currently do not have it installed, and have it "hidden" until I find a solution.
If I find a solution, I will post it here - please do the same for me. Thanks. Good Luck!

This was caused by a Microsoft update sequence error which they fixed last week.
Here is the full fix:
This issue may occur if specific Windows Updates are not installed in the proper order. Microsoft has made a change to prevent further customers from getting into this state. Customers must now have a pre-requisite update (KB 2883200) installed before being offered these updates.
To restore wireless connectivity:
1. Uninstall all of the following updates:
· KB 2887595 – Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 update rollup: November 2013
· KB 2903939 – Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 update rollup: December 2013
To uninstall an update, go to the Control Panel and select Programs. Then, under Programs and Features, select View installed updates. Select the updates listed above and click Uninstall. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
2. Install the updates listed below. When you run Windows Update, the updates will now automatically be installed in the proper order. You must restart the computer after you apply each update.
· Install KB 2883200.
· Install KB 2887595 and KB 2903939.
