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.

I too had intermittent connectivity issues on my Vizio CT14-A0 Ultrabook. I upgraded my Qualcomm Atheros AR5BWB222 driver from version 10.0.0.220 (one on Vizio support site) to version 10.0.0.221 (from www.atheros.cz), both for Windows 8. Problem no longer exists with this new version for Windows 8 - no more dropped wireless connections. Thanks to all!
CORRECTION: I updated the driver to the Windows 7 (64-bit) version 10.0.0.221. Seems to be working without dropping wireless connection now. I tried the Windows 8 (64-bit) version 10.0.0.221 previously and improved the bandwidth and connectivity but it still cut out periodically, just not as often. The Windows 7 version appears to be the way to go, even if you have Windows 8 (64-bit) installed like I do.

Pieter,
Worked flawlessly under 32Bit-Win8 Enterprise. You rock!!
Thanks brother...
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.
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.
