Geo Location App wrong/hops with second hand Wifi Mesh network

This is very strange. I bought a second hand TP-Link Deco M4 Mesh with 3 devices. After configuring on 2 iPhones the geolocation keeps hopping from my home (or Wifi neighbours wifi?) to the old address where they came (previous owner) from. Very frustrating because I have automations which use geolocation when I’m from home etc.

I did google some and seems that it has something to do with Google stores BSSID? to determine geo location??
Can’t figure it out how to correct this. At this moment I have to disable automations and location.
Hope someone can help.
Maybe I can do something in the TP-Link Deco App or is this pure a Home Assistant thing? Because Google Maps and other Apps have the right Geo location.
