Just over a month ago me and my dad moved. We're still in the same city but we got our internet service moved to the new house while continuing to use the same router. The issue is now that when using my phone or computer on the internet, Things like Google Maps or any app that uses my location shows it as being at my old house rather than our current location. I've read that this is due to a "Geolocation" being attached to the MAC Address of the router, and that it should update in time, but after a month of waiting it still hasn't changed. Any solution?
Wait longer. GeoIP databases can take a long time to update depending on how much money companies want to pay the database company for the updated records. Last time I got a new IP address it took a couple months for Google and other sites to realize I'm not in Halifax (last location that IP was in use) even though I'm in Alberta. Normally if you move from one house to another you'd likely lose your old IP address in the move so it may not be GeoIP related. Try shutting off wifi and see if your phone can see your real location.
The other thing that may be part of it for Google specific services is whether or not you've updated your address with Google. If you have a Google profile or have contact info for yourself in your Gmail or other Google service, and it still has your old address, that may be one possibility. Could also be from cookies in your browser too or cached information for the apps.
I find lots of location services place me somewhere in southern Ontario, if they can place me at all. Google collects geolocation information when their vehicles do mapping, and other data collectors mine data in similar physical ways. It may be some time before your location gets updated.
