If you have access to your router configuration, try deleting the Digix MAC from the DHCP settings, and then attempt to reconnect. If that fails, see if your router will allow you to reserve an IP address for the Digix and then just assign that address to the Digix.
The second option does not truly fix the DHCP issue, but it does get your Digix on the network without having to enter an IP each time, and then you can run down the DHCP issue at your leisure.
