Refer to the image above, and configure the router IP address and subnet to whatever you need for compatibility with your network. Leave the "Enable DHCP" box unchecked and the DHCP service will be disabled.
Once you save those settings the 2wire will seem to disappear. You have to re-access the 2wire UI using the IP address you just configured it to use. This means you may have to reconfigure the IP on the computer you are using so it is on the same network as the one you just assigned the 2wire to. Everything must match.
