I installed Virtualbox on Windows 10 machine and then installed ubuntu 14.04. But I have a problem with the internet access that I can't connect the ethernet network, while I still normally able to connect in my windows machine. And one thing that I want to ask is in my Network setting, the option Enable Network Adapter is disabled, I can not choose it, does anyone have an idea?


  • Do you try with bridged mode . – sohel4r Jan 24 '16 at 13:15
  • yes, but it still also not able to choose Network Adapter – Ock Jan 24 '16 at 13:20

It's disabled because you accessing the settings of your VM while guest OS is running. You should shut it down first, and then try to use NAT instead of Bridged mode.

  • aha, yes now i can choose the network adapter, but i still cant connect to the internet T.T – Ock Jan 24 '16 at 13:54
  • @Son did you also try to select different hardware like described here? Try to select different adapters. Maybe this will solve your problem. – incBrain Jan 24 '16 at 14:26

I had deleted the guest account on my instance and INSERTED my MAC address from hardware into Ubuntu network settings. I used Bridged adapter and PCNET fast III. (Virtual box on MAC)

This is my first answer so go easy on me!


Following settings worked for me:

I also refreshed the MAC number (see the refresh button next to MAC number, press that.)


I think you need to check the option that says “Cable connected.”
