I am having the infamous issue of random disconnects of my wifi card which is seen as a "limited access" indicator in Windows 7, however, even pinging the router fails.
my two laptops, having two different intel wifi cards suffer from this, but both at different sevarity levels.
After reading a lot of posts regarding similiar issues, it seems that this is a combination of windows Power management profile and the Power Save Polling feature on routers.

Although I downloaded the latest intel driver 13..2.1.5 which should fix the issue or work around it, i still found frequent disconnects until I followed the instructions in the aforementioned link which seemed stable until it disconnected while i was writing this post

I will do further testing, perhaps that was a real internet disconnection and not similiar to the issue at hand.
Can anyone help out in indicating if this feature is indeed missing or incomplete?
I had similiar issues with Tomato firmware but less frequent on one of the laptops.
Thanks
