Qualcomm Artheros ar5007eg drivers

Question

Hi 

I am running windows 8 prerelease and now my Qualcomm Arhteros ar5007eg wifi driver is not found. when I try to update drivers it says that i have the most updated driver. Earlier today in the wee hours of the morning there was an update for this driver and yet it would not install on my system. Now I am trying to find this update online because windows update does not have it as an update anymore. Very strange because it was there in windows update around 1 am this morning. Did windows update just loose it or did microsoft just take it away from windows update ? Did anyone else have this problem ?
