Well that might depend on how that Static IP was setup.
a) Manually. REF https://portforward.com/networking/staticip.htm -> Select your OS and Version
b) Or by telling the NAT router to your give a given MAC/Physical/Hardware Address, the same IP Address each time.
REF to the manual/User's guide for that NAT router
Advanced -> Network Settings -> IPv4 Address Distribution -> DHCP Connections -> Add Static Connection. Seems to be page 146 of 191 pages of that REF PDF file.
