I am researching this same problem...I am showing that the media state is disconnected in both the Ethernet adaptor in the wireless network connection and the same in the Local area connection. I have a desktop that is working fine and another laptop that is fine but suddenly my Lenova laptop cannot cennect to my Belkin router...I have checked the DHCS, TCP/IP, DNS and all appears to be restarted and on automatic. I have rebooted the router, disconnected & reconnected the ethernet cable and still nothing...on day 6 of this issue. I am showing that the Lenove sees the Belkin and has excellent signal strength but cannot acquire the network address, HELP! Please and thank you in advance!
