All early up-daters of Windows 8.1 had a problem with WiFi, most of them had Atheros WiFi device. The problem was conflict of drivers, that is Windows 8.1 automatically conflicts Atheros drivers with Realtek drivers. I personally posted a question in answers.microsoft.com and I tweeted this problems to a Windows MVP named Richard Hay, A programmer named Rephael Martiez and the official Windows support twitter account. I posted my tweets on 27th June 2013 and for two days no answer at all. Richard hay said this is a driver compatibility issue. Rephael said he is also having the same issue. Official Windows support people are yet to support me. They said its will take 72 hours to get support. I mentioned Lenovo in my tweets but those folks never consider me ( I use Lenovo G570).
So NO ONE SUPPORTED ME WITH THIS ISSUE BUTGOD. On 29 th June about 6.30 I found the solution for this problem and its working 100%, THANKS الله.
This is my solution.
Install Atheros driver which was working well for you in your Windows 7 or Windows 8.
Open “Device manager”. Still you have the conflicting “Realtek driver”
Uninstall it and right click on Atheros WLAN driver
Click “Update Driver Software”
Select “Browser my computer for driver support”
Select “Let me pick from a list of device drivers on computer”
Now select “Qualcomm Atheros…….” and press “Next”
YOU ARE DONE :)
Now you can see WiFi in Network charm.
