I have tried DHCP and Static on two different subnets of the network here.  The gateway is correct.  In fact, the device will actually set the NTP time, so it has internet access, it’s just once it starts normal operation it seems to no longer be able to reach the gateway and it spends all it’s time in a loop.  I’m pretty much baffled, the only thing I haven’t tried yet is setting it up on a switch so that I can use wireshark to monitor its network traffic, which I’ll probably do next week when I have some time.
