The default action is to connect to network via DHCP, no manual options appear to be available - however you can set up a manual connection, one example:
1. Disable DHCP on your router.
2. Boot box.
3. Check Network settings, Auto appears as the only option, press OK.
4. After approx 30 seconds, and error message appears, and you will then have access to a manual setup option.
