Moved across country with same WiFi network - now location won't update

I just moved from Los Angeles to Connecticut. I kept my Wifi router (Google Nest Wifi), and just reconnected it to the new modem in the new house, so the network name and settings are all exactly the same (except presumably the IP).

My MacBook has location services turned on, but it is under the impression I'm still at my old house - I see this both in Date & Time settings, as well as logging in to Find My. Which is not ideal. My hunch is that it thinks that since it's connected to the same Wifi network it's in the same place (since I know part of how it determines location is Wifi networks...) but that's no longer true. I've tried restarting, as well as turning location off and on again.

How can I convince my computer that we've moved?
