Vista Wifi sleep problem - I have solution but can't implement it!!!

I just bought the Asus G51 from BB. First computer I've run with Vista on it. Finally have fixed all my connection problems with this damn OS except one. The wifi not working after sleep mode. Here's the fix from ms http://support.microsoft.com/defau [...] 3872/en-us Here's my problem. I have service pack 1. Came factory installed. However when I cross check the three drivers under Vista 64 my Dhcpcmonitor.dll is an old dll. Older than the listed fix. But because I have service pack 1 installed... When I try to download and install that hotfix...it says it is unecessary and wont let me install. The other two drivers are more current than the listed ones. I really want this fixed. Any Ideas??
