Is it just me, or is Wiznet not working in V77?

I know it was working just after my Picos arrived, but tonight I tried in several network ports with two different wiznet modules.... The basic demo code just hangs:

SPI2.setup({ mosi:B15, miso:B14, sck:B13 });
var eth = require("WIZnet").connect(SPI2, B10);
