Welcome to SF,

First thing to do is download the latest driver from the Manufacturer's site, then uninstall your network adapter from Device Manager, then manually install the latest driver.

Please post back if that helped or not.

i did it, but no succeed. today i bought ne Wireless USB adapter and it disconnects me again evvery half an hour ..i think that something is wrong on my windows. but don't know what

What type of Firewall or Security Software do you have?

what do you mean..what antivirus program i have or? if you are not asking me for antivirus tell me where to find out name of firewall

I need to know if you have any Security or Firewall software installed, it might be creating an issue.

You may also try disabling any Power Savings of your Wi-Fi Adapter in Device Manager. Locate the Wi-Fi adapter, choose Properties, in Power Management Tab, uncheck the boxes.

Install and run Xirrus Wi-Fi Inspector from your wireless computer.
Double click the Xirrus Icon on your desktop, Tap the Printscreen key on your keyboard, open up Paint then choose Edit from the Menu and select Paste, then SAVE it. Upload and attached it here.
