You need the WLAN drivers directly from the laptop manuf. site...
If that driver came from Atheros you will continue to have issues.I downloaded the latest driver from official asus site but this is still happening.. "Network Controller" always failed to install whenever i install WLAN driver.. Wifi Only work if i go to device manager and select Network Adapter and scan for hardware changes..  but sometime it also failed to show atheros adapter..  Need Help Immediately..  My OS Win7 64 Bit Ultimate..
PS- i reainstalled OS but it didnt work..

How can i Fix this. or how to install device driver name "Network Controller"
..
PLS Help
Did you install the chipset driver first after reinstalling Windows from the Asus support site? Or try going to your device manager - Atheros CARD and right-click - Properties and toogle the Power Management tab power saving feature. i used Asus Driver CD.. it install Driver Automatically,  chipset driver also installed after installing windows..  .problem still occuring.. need helpIs the ASUS driver CD for 64bit Win 7 ? ?YES.. its original Asus Driver CD And it includes 64 bit drivers...correct ? ?yes..  windows 7 64 bit driver CDWhy no one is replying  A workaround for 64 bit Windows 7 is:
A ) get on the Internet direct wired Ethernet cable from the modem./router and forget about  wireless.
B ) Buy a low-cost Wireless adapter that  has drivers for 64 bit Windows.

Many Wireless adapters show up as network cards. Additionally, either windows or another program has to connect to the wireless router. This can take up to a minute  after windows starts.

A wireless USB adapter from a major  company will now have all drivers on a CD. And you do not need the highest speed, Even the lower speed is faster tat what you IPS will let you have. Should be under $20 for the standard model.

Thanks for reply.. but i know its driver problem.. sometime it load sometime it dont load with boot.. i just want to know how can i fix this.. or shud i upgrade to win 8.1? will it work fine on win 8.1??

You never replied whether you re-installed ALL Win7 64 bit drivers or not...
There should be a WLAN driver listed but chipset drivers go 1ST...
If you have DONE all this and re-booted and it's still the same then the issue is with the router itself...yes i installed all windows 7 64 bit driver with chipset first.. CD automatically installed all those.i saw it installed chipset driver first.
Then it's the router...
Or a flakey connection...try speedtest.net see what your connection speeds are.
