@erdeed Again, you’re not a clear writer 
. And as someone else pointed out, besides me, there’s many reasons this could go wrong.
You keep mentioning in a “brume router” and how you think this device is giving you away. Google may have already scanned and mapped that device: research how Google maps wifi devices for location services.
Change the MAC addresses and all other information you can think of, for example wifi name, on the router that you think is giving you so much trouble.
Maybe it’s not the mini routers you seem concerned about and rather something else. For example, turn off “location services” in OS X – or search for something similar in your operating system. The location of your computer could be identified via bluetooth via proximity to phones. Your laptop could be identified via wifi signals via proximity to other networks (but you mention an ethernet connection).
There’s probably many other ways to identify your location that I don’t know about. And your situation is unclear.
Try changing time zones of various devices. Maybe you’re operating from a work laptop with more sophisticated location tracking software in the background. Etc…
And the VPN is between which devices exactly? At what level? How is it configured? How many VPNs are you using? Maybe if you drew a chart it would help.
