Windows 7 - WLAN Adapter missing after install Windows7 Ultimate 64bit

Help...!
I've just upgrading my Windows 7 Ultimate to the 64bit version on my Asus Netbook eee PC1201T.
After that it couldnot connect to internet via Wifi. I found out that the WLAN Adapter is missing from the Device Manager. I want to re-installed the WLAN Adapter from the Asus DVD, but it said "We didnot support this Operating System!!!". So I brows the net and from the Asus center I downloaded the driver (Wlan-ANE107H-v2007_1_1002_2009). Some body w the same problem did this and workout, but when I installed it, it brought up same comment. What am I going to do??

Is it because I use the 64bit version? I also notice the Hotkey not working (the Fn, Fn+ F11, Fn + F12 (sound)), is this also related problem ?
And also where can I find the 64bit Driver?

Thanks
Kris

The spec:
Asus eeePC 1201T
CPU: AMD MV40
Chipset: RS780M
VGA: Mobility Radeon HD3200
RAM: 2GB
The WLAN Adapter: Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC

try this driver directly from realtek: Realtek

the driver you need is the sixth one down the list. if that doesnt work, try the vista 32/64bit driver (fourth in the list)

do you have 2 network carsd? one wired and one wireless?

Yes, Kword88

have you tried installing the driver in compatibility mode?

right-click the ".exe" file you downloaded from asus and click properties. click the compatibility tab and select an operating system from the list. if one doesnt work, try another.

Okay, I will try that.
I will tell you the result

if the file you download is a "zip" file, you need to unzip it first, then find the executable file in the resulting folder. if there is more than one .exe file, change them all.

It doesnt work.
But I have made a decission to change the system w the 32bit version. Somebody in another forum its useless to use the 64bit on eeepc (only 2GB RAM), and another one told me the 64bit will bring alot of trouble in compatibility.
What do you think?

Kris

probably true. but you will have to reformat the hard drive, so make sure you back up all your personal files.
i dont think you will see a difference using 32bit instead of x64, and you should have no compatibility issues.

Okay then.
Thanks anyway for your attention
