[Q] Is there a way to change my WiFi router Location (detect by Google/Android)?

---

For some reason my router’s location is way off (in a different state). I bought it off eBay few months back, perhaps it is still showing previous owner’s location.

From what I could find out, Google periodically updates their location database with data gathered using their street view cars or with those anonymously submitted by users (using apps like Google maps mobile). Now I’m wondering if there is a way for me to manually submit my own data or better yet somehow enter my WiFi router’s location data into the phone so whenever I’m connected to my home WiFi my location wont be detected at a different state?

If changing WiFi location is not possible then is there a way to at least give Cell tower location priority over Wi-Fi ? Because my cell tower location is far more accurate (down to like 5km, which is much better than having a location in a different state 1000km away).
