Power Save Polling (PSP) & intel card issue

Hi,

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.
(http://www.intel.com/support/wireless/w ... 006205.htm)

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
Fadi

So, you are saying you have completely disabled any power-saving
features on the wireless adapters?

They are always set to be on?

I've got a Windows 7 with wireless-N usb - it never disconnects

I've got a Windows Vista machine with the intel 5x series
network adapter, turned off all power save features, and have
never seen it lose connection or drop wireless.

Vista uses same upgraded TCP/IP stack and same drivers as Win 7.

What kind of distance are you running this at?

What frequency - 2.4 GHZ?

Have you checked for wireless phone or microwave interference?
