Google Marking wrong location after new router supplied


[link to this post]
 
A friend of mine was sent replacement BT Home Hub to cure a problem. It appears to be a 'refurbished' one too.

All is fine, except Google now thinks he lives 400 miles away in Glasgow.

He thinks that location is determined by Google keeping a log of router MAC addresses, if that's the case, how do you go about resetting that, and if it isn't the case what's happening !?

Surely the location is based off the IP address. Changing the router will have allocated a different IP. As long as it’s not showing in another country then it should not cause any issues.

To add it will probably update at some point but it will be based on Google's algorithms to do that - how long it takes and how accurate will entirely depend on Google and if the IP changes again (which it probably will) then the location is likely to change again. Generally IP location services are poor and cannot be relied upon for anything.

If he has a smartphone on the WiFi with GPS and uses Google maps, or almost any google app, it will eventually update. Give it a couple of weeks.

Google puts me all over the place. I'm in London. Google has shown my IP location as being in North London, West London, Manchester and somewhere in Cheshire. Currently it shows my location as Woolton Hill near Newbury in Berkshire.
I have location services turned off in Windows and all other devices.
It could be if location services are turned off it takes the area from what server i'm connected to as my current location.
Either way it doesn't bother me.

I'd be surprised if Google had any record of the hub's MAC address unless a Google Smart Home device is connected to it and I'm not even certain about that.

As I undestand it, it may be possible to extract this information from Internet Explorer browsers which have ActiveX enabled for a particular website. I don't use Internet Exploder though so haven't played around with this.

The question I'd really want answering is what issues is it actually causing your friend? From my point of view, if Google doesn't have a clue where I am that's a big plus.

I may be missing something here but what would the benefits of that be to him? As far as I can tell the only benefits would be to Google because he can then be targeted with location accurate adverts.

I completely agree, and personally don't have Google maps installed on my phone. My location is fairly accurate because I use Virgin Media's cable service, so the IP range is specific to my town. Other ISPs that are accessed via a PPPoE session can locate you anywhere. A friend of mine across town usually appears as being in Oxford on his VDSL. smile

Google uses Android phones to log the location of Wi-Fi access points to supplement it's location service, it uses the Wi-Fi's MAC address and Android devices that are in range that also know exactly where they are from GPS. This then allows other devices to know where they are if they don't have GPS, and/or provides a quicker location fix.

If the access point was used in a different location, the MAC address is likely already registered at that other location, giving the wrong location for any device using the Wi-Fi MAC address to find where it is.

Eventually Google should update the location as Android devices that pass within range that also have a confirmed GPS location will tell Google of the access points around it, and Google will notice the access point has moved and update its database.

The only way to stop this happening is to append on the access point SSID "_nomap", see https://support.google.com/maps/answer/1725632?hl=en-GB

Thanks to all, @E300's explanation would seem to make sense.

As for why it's a nuisance, well it doesn't make searching for local goods and services via Google very user friendly ?
