Ubuntu Networking :: Have No Internet Connection In Gnome As Well In Kde / Sort It?

I was not connecting to Internet in kde so i edited auto etho settings i make some changes

but alas! no Internet connection

and the worse thing is that i lost connection in gnome desktop too

but it is showing me i am connected to Internet
but i cannot surf (server not found))

{i changed the setting to default {{after i changed them in kde ]]

and notice following

in edit auto etho connection
connect Internet automatically-yes

ipv4 setting--
automatic (dhcp)addressees nonly

ipv6 setting

ignore

so ubuntu is showing me that i am connected to Internet but i cannot access Internet

so the main problem is ""ubuntu is showing that i am connected to Internet but my browser says no server found and i can not install software in software center it gives me error --please check you Internet connection
