WIZnet WIZ550io

This code ..

E.enableWatchdog(10);

var eth = require("WIZnet").connect();
eth.setIP({ 
  ip : "192.168.254.248", 
  dns : "208.67.222.222",
  gateway: "192.168.254.100" });

var http = require("http");
http.get("http://www.espruino.com", function(res) {
 res.on('data', function(data) {
  console.log(data);
 });
});

works once and the console fills up with the HTML returned. If you try to run again, you get

reset();

ERROR: Socket error -7 while sending

So sort of heading in the right direction. Totally mystified by the DHCP behaviour really. Can't persuade the server code to work at all.
