panasonic viera tv won't connect to linksys router wirelessly using Lan adapter....any help here

I'm having the same problem. It says my LAN cable is not connected when it is. I am using an airport express which is linked to my airport extreme.

try going into network management in poperties on you device left click to do this, go to advanced , there are 2 radio buttons that say find IPS and DNS automatically,click on them click OK click OK again to close all Boxes and now restart your computer ,this should match your IPS to Your DNS ,good luck
