Howdy folks, I've experienced an interesting issue with geo location on my Android phones.
I noticed that after I moved to a different part of town that my Latitude kept showing me at my old apartment. I thought maybe Latitude was remembering my home location and going by the time of day that I'd be there. Then, an out of town friend came over and his Latitude was showing him at my old place as well.
It dawned on me what it might be. I use two wifi routers to extend my wifi network via WDS. My understanding is that Google's positioning is based on/assisted by locations of known wifi SSIDs. My supposition is that the phones' locations in my new apartment are being based of the former location of my routers.
Has anyone else experienced this? How do you force a location update to the wifi database?

Odd issue after a fresh flash of Bionix NextGen...
My wireless network location will only show up in maps when Wi-Fi is on (connected or unconnected to a network), when off and when only connected to data location will not update and remain stuck at the last point I turned Wi-Fi off. I've tried flashing a new modem and wiping dalvik to no avail. (Yes, location is enabled in settings). Anyone else having a similar issue?
Edit: Apparently, the location is just not registering on 3G/HSPDA networks...I forced it to use 2G network and location immediately registered. Any ideas on how to fix this? Possibly a T-Mo network issue?
Same happened to me on AT&T network. It takes time for Google to recognize newly installed/updated towers.
Strange. Never had this issue before on HSPDA network and I'm in a location I've frequently been to. I'll just wait and see when it corrects itself.
Maybe a bad flash? I came from stock jfd..how long did it take google to recognize your location.
1-2 months.
Now lets say I am in Paris but I use VPN with a US IP which places me in Scranton NY. When I am on my PC I am shown in the US. It looks to my IP address. Speedtest also proves this. But on my GT 10.1 using wifi from the same router with US based IP I am seen at Paris. Since GPS turned off and since no sim, no cell towers... Speedtest mobile looks for the nearest server and it is where I am actually at. Maps too. How does it do that?
they are just smarter than what you think they are
You probably enabled WiFi based location... Every WiFi router has a unique MAC address.
To keep it simple: Google keeps a database of MAC addresses and their location on the world. So when your Galaxy Tab asks Google where it is it sends your WiFi routers MAC address to their location service and gets the location associated to it.

Thanx Wubdidu,
Very informative. Now I know.

hi, can you tell me how I exchange router location,because every time I connect via Wi-Fi my phone changes location where i used router before which is 60km away from me now.
Thanks
Pretty much what the title says. Why is Google and android so persistent with wanting me turn my WiFi on. Even if not connected to a router they say that it helps determine location?
I know for a fact that it helps drain my battery. But I'm not convinced it would help determine my location in any way. In other words. If I have a GPS lock there is absolutely nothing that WiFi can do to help get a better lock in that situation. Also let's say that I don't have a GPS Lock but my WiFi is turned on but isn't connected to a router. Then there is nothing WiFi can do to help in that situation either. Downloading aGPS data requires Internet which is provided through the cell network not WiFi.

Because google have records of lots of wifi networks and where they are. Your phone can scan for networks, google can see if any near you are known to them and if so then they can narrow down where you are.

Hello everyone,
I'm a longtime lurker of XDA ever since I switched from my Palm Pre (RIP) to an HTC Evo 3D. I created an account finally to post this question and I'm hoping someone can help because I am at the end of my rope.
My Nexus 9 has a wifi issue that cripples my entire network. First, I'll give you the details of my configuration and the problems I'm running into:
Running an ASUS RT-AC66R on Centurylink DSL. I have tried both the 2.4 and 5GHz bands. I have tried multiple channels per band with no effect on the issues listed below. The 5GHz band is currently disabled.
Unless I am am running the factory image that came with the N9, my wifi connection will almost completely dry up across every device on the network when the N9 is connected. As far as I know, this only happens on my home network.
Restoring the N9 to factory settings - which I have now done twice since purchasing it on Nov 3 - eliminates this problem almost entirely until I install the OTA update. This problem happened with both the day one patch and persists in the recent update to 5.0.1.
If I am playing my PS4 or streaming Netflix (or anything that requires a connection), I notice the connection speed rapidly drops to somewhere in the range of 0-5 kb/s as soon as my N9 connects to the network. When I deactivate the N9's wifi, the connection returns to normal speed immediately.
I am still connected to the network when speeds are low, but data crawls. I am able to connect to the router's config page and can see that traffic caps out at about 5kb/s down and 60 kb/s up.
Here are some of the fixes I've attempted, which all failed to produce results:
resetting the router
resetting my modem
disconnecting all other devices
switching channels on the 2.4 and 5GHz bands manually
updating the firmware of the router
changing the network name
changing the network password
changing the network security type
I am typing this after having reset my N9 to factory settings for the second time to confirm that the issue lies within one of the firmware updates. Can someone please help a networking noob figure out how the connection of one device quickly (within 15 seconds) halts all traffic?
I should mention that the exact same issue was present on my N5 earlier this year (long before Lollipop arrived) but that it eventually worked itself out and stopped hijacking my network. Unfortunately without mobile data on my N9, it is essentially useless until I figure out the issue.
Thanks in advance for any help!
The first thing that came to mind is an ip conflict. Have you tried changing to a static ip on your nexus 9?
Edit: Also when your nexus 9 is connected check and make sure the ip address on your other devices jives w/ you router (you may need to make all devices static until you find the problem) I had the same router as you and i had a network switch that was throwing odd ip address to devices not even attached to it...
I updated to 5.0.1 again and didn't have any issues this time around. I went ahead and set a static IP anyways but I'll report back here if I have any issues. Thank you!
This applies to both my phone (Samsung Galaxy S6 Edge Rooted) and my wife's phone (Samsung Galaxy S5). We are both on Verizon.
We recently moved about 20 miles down the road and ever since, both of our phones still think we live in the other city. For example, Weather Bug constantly shows the other city. If I start Google Maps or another GPS application, the initial location is the other city (my actual old house location) and then it quickly "finds" us where we actually live when the real GPS kicks in. This happens on both Wifi and on mobile network.
If I go to any site that does IP location, it always shows my ip as the city I live in. I thought maybe that since I still use Comcast that my IP was registering the old address or something similar. I went to the extent of doing a mac clone on my router to pull a new Comcast IP with the same results. IPV6 is turned off.
I have also tried clearing data on all google services, deleting location history, etc. I also updated my address in Google, my home location, and every other spot that references the old address. Something that does work is to turn off all other location types except just GPS, but then it has to use my GPS more and results in more battery usage.
Since this is on both of our phones and not limited to one, what other options do I have? How do I get Google to update my location based on cell towers, IP, or whatever else it uses for non-GPS location?
Any help is appreciated. One of those minor issues that really just bugs me more than anything.
