Well I resolved it by bypassing the wireless adapter and buying a nano external wireless usb thing, it works perfectly now. problem still not fixed however.
I found a way to fix my Network, ive manually uninstalled the Network cards Drivers and downloaded the following file "win78-10.0.0.75-whql" from
http://www.atheros.cz/atheros-wireless-download.php?chipset=81&system=6
and simply installed the driver via the Device Manager
Hope this will help some of you.

On 5/20/2013, I have tried to download "win78-10.0.0.75-whql" several times from the link you provided. I've also tried to download "win7-10.0.0.234-whql" as well as "win7-10.0.0221-whql" several times and each time when I try to open the file, I get a "file is invalid" error message. When I right click on the file to extract it, I get an error message that says "the compressed folder is empty. you must first add files to the compressed folder". Is this likely a problem with Atheros's website or my computer? Has anyone else had this kind of trouble? If anyone else could provide a functioning link to the necessary drivers, I'd really appreciate it.
Also, when you say "manually uninstalled the network card's drivers", do you mean without using the "uninstall" option via the Device Manager? If so, could you please explain how to manually uninstall the drivers?
Thanks.
I have tried to download the driver you mentioned twice now and each time I try to open it, I get an error message saying "file has been corrupted". This problem is driving me crazy, I've tried several suggestions from the users on this thread and nothing seems to work for me.
