Arduino Yun WebClient Examples

Hello - I was wondering if I could get some help with my Yun regarding the WebClient code example. My Yun is connected by Ethernet and I can see it on the router and access it using a browser.

When running the WebClient example, I get the "Failed to configure Ethernet using DHCP" message, then "connecting..." forever. As far as I can tell it is not getting out of setup().

There is a related code example here:
http://playground.arduino.cc/Code/WebClient
but this just hangs Java and the IDE locks up.

I have used IDE 1.6.6 and also tried 1.6.5.r5. The Yun is an Arduino.cc device. Thanks.
