I recently bought a dell inspiron 5520 laptop and I am able to connect to internet using my broadband ISP username and password and they had provided their own modem which works like a charm..
But as soon as I try to connect my laptop to LAN using the Ethernet cable in my room it says "LIMITED CONNECTIVITY" and while fetching the details of connection it shows -
IPV4 - NO INTERNET ACCESS
AND IPV6 NO INTERNET ACCESS
though it shows large amount of data sent and received.. but in the taskbar it shows a yellow exclaimation mark along with the network symbol
and hence I am not able to surf internet.. All my frnds are able to do the same using their laptops in my room .. NOTE- LAN GETS CONNECTED USING THE ETHERNET CABLE IN MY HOUSE..THE MODEM WORKS FINE AS OTHER FRIENDS ARE ABLE TO SURF
and as for the wifi...
it scans for networks and shows limited connectivity and I cannot access net ...it also shows a yellow triangle at the taskbar above the wifi symbol
