Atheros Wireless Conenction Issue

I am having a problem with my Wireless Internet Adapter.

It is an Atheros AR5B91 Adapter. I will connect to my router sucessfully, and if I am NOT downloading anything, or just browsing the web, It will go to "Limited Connectivity" after about 3 or 4 hours. And I am not able to go on the internet at that time until I turn off then turn on the Wireless switch.

It will automatically reconnect to my network and be good for another few hours. If I am downloading something (As of right now, Im downloading Office 2010 trial from Microsoft) It will download then go to limited connectivity in about 45 minutes - 1 hour.

I am running Windows 7 32-bit. The driver is up to date.

I would usually be able to solve this issue on my own, as i am not stupid when it comes to computers, but this one stumps me.

Any assistance is greatly appreciated.

I wonder if Windows is turning off the power to your wireless adapter to save the planet.

 

Look in Device Manager for the wireless network adapter's properties. Make sure all the power saving options are turned off.
