Hi, I have a problem connecting to wifi on my laptop. It's funny because when I plug in an usb adapter (D-Link) it works fine. It's also funny because the built-in adapter in the laptop does see all the networks, also when the computer tells me if I give a wrong key to the network. I have installed the most recent drivers, the problem is the same with WEP, WPA and a not secured network. The computer is MSI Wind u230, the os - Windows 7 with all the updates, the adapter - Realtek PCIe GBE Family Controller.
