WNDA3100v3 – N600 WiFi USB

What is the newest driver for windows XP  and where to get that driver ?

Also using a older driver for V3, it goes to sleep and quits working

so using a desktop as a file server the clients do not see that unless I go to that desktop and do something like going to the interent and then V3 works but over time quits working again

Looking at V3 settings with the older driver has nothing abut some sleep mode setting so how to solve that so it is always functional ?

Thanks
