Your model of the laptop seems to have a realtek lan adapter.
Try this driver from the official web site, it should work:
RealTek LAN Driver

Try this...

1. Go to "Control Panel" and then open "Device Manager".
2. Here click on and open the "Network Adapters" section.
3. In the list that drops down below it you should see one option for LAN.
4. Right click on that option and then click on "Update Driver".
