Model : TL-WN8200N

Hardware Version : Not Clear

Firmware Version :

ISP :

Hello,
I've connected wn8200nd to my desktop pc with a Windows XP.
I've installed the driver and the utility, but cannot connect to wifi.
I see the access points only when I use the Windows connection tool, but when I connect - I don't have an Internet.
When I try using the TP-Link utility - I get a message "Cannot switch on the adapter..."

Looking forward for your help,
Vitaly
