Windows 7 : Ethernet or LAN is not connecting to internet but wifi is

To troubleshoot this problem, I did restart of that laptop and tried, changed LAN cable and port, but not worked. At last, I deleted the concerned LAN drive from the following location

Go to Control Panael - >Device Manager ->Network Adapters ->Intel ....()

and restarted the Laptop. Now I think it reset the adapteer automatically, but now it works fine both LAN and wifi.
