Changing GPS location of Apple routers I have recently moved and have moved all my network gear with me.   Have approximately 4 wifi spots that I have re-set up in my new house.

To save battery apple devices also use location of known wifi hotspots to give locations.   My problem is that I suspect that this is a crowdsourced information gathering.   Sometimes my devices show themselves at my old house (while at new house).   I have waited for 2 weeks now, trying to use location services as much as possible to train apple about the new location of the wifi spots.

Is there anyway to force or speed up the change?   My alternative is to change the name of the hotspots, but do not want to go through the hassle of setting everything (range extenders, devices) again.
There's a company called SkyHook that sells a wifi-based geolocation product to many companies, but not sure if Apple is one of them. It was a couple of years ago though. 

You can ask them to update their database here: http://www.skyhookwireless.com/submit-access-point. If Apple is doing their own geolocation services now, you're likely out of luck.

ETA: changing your (E)SSID probably won't do anything; the location services are more likely to use the BSSID, which is the wireless MAC address of the equipment.
