Wifi connection failed, no Wifi found error

[SHADOW-XIII]

While using my laptop I got strange problem. Suddenly I'm loosing my Wifi connection and when I try to look for any wireless networks around it says that no networks were found - that's not true, all neighbours and mine are working fine (like 8 of them total). Only restarting computer helps.

I found those details inside event manger, this two events appear exacly same time to a second:

Event 11002:

Wireless network association failed.

Network Adapter: Atheros AR5007UG Wireless Network Adapter

Interface GUID: {3E2236AC-16C6-4222-A0EA-F3075525D885}

Local MAC Address: <ereased for forum>

Network SSID: xxxxx

Failure Reason: Driver disconnected while associating.

and Event 8002:

anyone have idea what cause the problem (I bet it's network drivers but those are the best I could find), or any possible fix?

Thank you for any help in advance ...

Try this

Go to properties for your wireless lan card in Device manager . Go to the Power management tab and uncheck the "Allow this computer to turn off this device to save power" option
