I just buy a Lenovo G550 laptop with Windows 7 Home Premium. I found whatever using wire or wireless connect to my home LAN, Windows 7 got a very very very slow internet access by web browser, and Windows 7 makes the others PC's network connection in LAN down and up, down and up......... whole LAN almost be crash. After I turn off windows 7, network connections will be normal. Anyone has the same experience?
