How reliable is the ethenet on a FRDM-K64F or is it broken?

Hi,

Whenever I try and use the ethenet port on my FRDM-K64F for more than single packets it hangs. I've tried HTTP-Serve and RPC-Ethenet-HelloWorld and both hang soon after starting.

With HTTP-Serve it can sit there responding to pings without problems but once you start to get it to serve a page it quickly hands and stops responding to pings. There is no output on the serial console to indicate a problem and no flashing red LED.

With RPC-Ethenet-HelloWorld it hangs just after connecting with the server. Sometimes you get a flashing red LED but not always and doesn't give any output on the serial console.

So is it that the driver for the ethenet port on the board is very unstable or do I have a broken board (other programs that don't use the ethenet port work fine)?
