title: Force Android to use 3G when on local area wifi without net access
body: <p>I have a wifi LAN setup which does not have internet access. Just various other local wifi devices connected to it. The DHCP is configured to not return a gateway or dns server. Only an IP and netmask.</p>
  
  <p>When I connect my android to this wifi AP it connects fine, but all internet connectivity on the phone stops working.</p>
  
  <p>I would expect that since the wifi has no gateway setting that android should realize the internet can't go through that connection and should instead be routed through the 3G connection which is at 5 bars.</p>
  
  <p>I've tried setting a static IP on the android phone as well, but this did not help.</p>
  
  <p>The main reason for this setup is so that the android device can transfer data on this remote network to an internet based server since it can connect to the local devices without issue. However the 3G side is broken once the wifi is setup.</p>
  
  <p>Any thoughts on how to work around this issue?</p>
