How to enable internet access inside Vagrant?

Question

If I run curl google.com, I can\'t see the output, only a blank page. My Vagrantfile contains:

Vagrant.configure(\"2\") do |config|
  config.vm.box          


        

Answer 1

This happens sometimes for me if I switch the host network connection, like disconnecting my laptop Ethernet cable and start using the wireless network. I found that rebooting the Vagrant vm (vagrant halt, vagrant up) fixes things.
