Renewing DHCP Lease on DSM

When setting up a DS923+, I added a reservation for IP address to my router. So I was wondering if there is a way to get DSM to pick up the new (and henceforth static) IP address quicker than waiting for the current one to expire (which would take about 22 more hours). On Windows/Mac there's an option to renew/refresh DHCP in network settings. Is there an equivalent thing I can do on the NAS? If not, I guess I can just wait around for it to get refreshed.
