Wifi dropout

Hi all - Firstly i've searched the forums and online and found no answer to this so here goes.

I'm running an early 2011 macbook pro with windows 7 and the latest bootcamp. The issue ONLY happens within windows.

Connecting to a wifi router is fine, however sometimes (randomly it seems), the connection just drops. By drops i mean the wifi status is showing connected, but the internet doesn't work. After a while it seems windows recognises this and puts a limited connectivity dot over it.

A disconnect and reconnect works fine, but obviously I need a reliable connection for uploading etc.

Any ideas or anyone had a similar thing?

 

Just for anyone having the same issues, a driver update sorts it. Acer website was the only place I could find it.
