You can set the static IP address on the device if your using an address out of the pool range on the router, so you want .220, just set it up on the device. You can also set up a reserved IP address on the router which is also recommended, however that would need to be with in the pool range, .100-.199. Once you have either method set up, make sure the old IP address that the router has been giving the device is revoked first, then restart the device and router and you'll be good to go.
