Atheros Ar5006x Wireless Network Adapter
Hi, When I tested Windows 8.1 Preview I had this same issue with the Atheros wireless connection. The same thing is happening with Windows 10 Technical Preview. So I am pasting the solution in case it helps: I own a Lenovo G470 and my problem is solved. Device manager was showing I had a Realtek wireless lan driver facing a startup error.
Download the latest version of Qualcomm Atheros AR5006EG Wireless Network Adapter drivers according to your computer's. Atheros AR5006X Wireless Network Adapter. Use the links on this page to download the latest version of Atheros AR5006X Wireless Network Adapter drivers. All drivers available for download have been scanned.
I tried updating the driver even with a LAN connection working but had no luck. Then I downloaded the latest Realtek/Atheros bundle drivers from the Lenovo support site, installed them and still no luck. The driver shown in Device Manager seemed to be the same that was installed before and still not working. So I tried to update the driver choosing the Browse My Computer for Driver Software / Let me pick a list of device drivers.
It showed three options: Realtek driver, Microsoft driver and Atheros driver. Tried each one, as soon as I chose the ATHEROS driver the wireless lan icon appeared and everything started working!
I hope this helps someone. Now my Windows 8.1 notebook rocks. Best regards and thanks for the help! I've follow your screenshoot and the checkbox was unmarked when it showed only the Intel and Microsoft entries.

Now it showed a lot more companies including Atheros and Qualcomm, but probably this is related to the fact I tried to install the drivers for Windows 8.1. Anyway, the Atheros drivers were only for ethernet cards, and the Qualcomm ones always returned an error 10 'unable to initialize device', also the one for my exact chipset (AR5004G).
Where can I get the hardware id? I'll open later the computer case to look directly to the card to see if I can get more info. Same problem with my i7 Lenovo Z560 - except I have just 'cleanly' installed the 'market release' of Win10 Enterprise (64-bit). And while I did not have to load an 'OEM' driver under Win10 'Insider's Preview' version, this 'market release' reflected that it found a Realtek wifi - not the Atheros. Using your suggestion, Cesar, I 'browsed' - selected 'Let me pick.'
- opted for the Atheros and my useless 'Realtek' wifi card became functional with the Atheros driver. And I'll make a note of this for my clients who will (no doubt) have similar 'mis-read' wifi and other hardware.
