Put this in a cookbook and put it at the top of your run list or base role.

ruby_block "check_internet" do
  block do
    require 'socket'

    test_host = "www.google.com"
    test_port = "www"
    retries = 0

    begin
      s = TCPSocket.new(test_host, test_port)
      s.close

    rescue Errno::ETIMEDOUT
      if retries < 3
        retries += 1
        Chef::Log.logger.send("warn", "Unable to connect to
#{test_host}:#{test_port}, retry ##{retries}")
        retry
      end
    end
  end
end
