Please explain. How does Google find my location? - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

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

TG01 wi fi woes

If you see this on Modaco, apols.
Hi folks, just picked one of these up for the £149 in Orange, but have a problem with wi-fi that I have had with a few WM devices over time, think its the AR6000 wlan chipset myself, seems very fussy about what and when it connects.
I would appreciate any help, but not please along the lines of "change your router", that ain't happening, it works fine with loads of other devices, so if this issue is non solveable, its the TG01 that goes!
OK, first connection to the Router (its a Billion ADSL) was fine, got connection, worked OK. From there in, as soon as it woke up, no dice, just unable to connect, always shows up in both WM and Tosh wireless util as available, just never connects.
Now, what I have noticed with this and at other times when I have had this issue with past devices is that it puts some odd stuff in the IP address field in the Configure Networks Adaptors screen.
I have it set for Use Server Assigned IP Address, but in the field below, I get this odd stuff fe80:221:e8ff:fe88 instead of 192.xxx.xxx.xxx that should be in there. I am sure this is somehow related to my connection issues, but searching the web, seems like noone else ever had this?
Kev
can u turn ur wifi off ?
and can u turn it back on ?
Yep, turns on and off no problem, even done hard reset to see if I can get that fresh connection, but no way.
That is your IP. You need to configure it with get automatic IP or put you the IP but is more complicated.
This problem have origin be tween router and mobile or pc. Some time routers didn't assign an IP address.
Some time have other origin is a key try to put the key in different form AES or TKIP nbest one TKIP.
Check to security type.

That looks like an IPv6 address as opposed to an IPv4 address, so I guess your router must be using IPv6. Does it not do this for your other devices? Maybe your router's DHCP serves up an IPv6 address because it detects that the TG01 can handle it. What happens when you try to do something meaningful on the network?
try and change your router security from wep (i assume it is due to a problem i have) and that seems to solve it,did for me neway and you are probably right about the chipset,

Is it an IP address, all my other devices show 192.168.xxx.xxx, not seen that format before.
Checked the AES/TKIP thing, and tried both to no effect.
Also tried to set a static IP, but no dice.

Hrmm, IPv6 address looks like
2001:0db8:3c4d:0015:0000:0000:abcd:ef12
Which is not really what I have, and nothing else uses it, in fact can not see any reference to IPv6 on the router.

Security is WPA2-PSK, which to be fair works on lots of other devices, and I don't really wanna mess with them

Put your configuration here and lets check if we have the same.
I have a similar issue using a Siemens Gigaset SE587 ADSL router at home with the wireless security set to WPA/WPA2 - it will happily connect me once, but subsequent attempts fail unless I reset the router. Other access points are fine. For example, there is a BTOpenZone router not far outside that I can connect to at will, with no problem. Also, the router we use at work happily embraces the TG01's desire to connect.
The SE587 has been a bit temperamental with certain other devices so I wonder if the issue is the slightly fussy router rather than the phone?
Oh well .. I'm picking up a second hand Belkin 54g router soon, so hopefully this will solve it.
Ok guys this problem how I said his origin is to not assign one IP address correctly. This problem is because of WPA2 crypt key.
Turn of your security in your router and try to connect and lets start talk then.
that address (the numbered one) looks like a mac address, if you log on to your router, set up a rule with that mac address and/or ip addres (try 192.168.0.4, its usually free unless you have more than 4 connected devices, if you have then up the 4 to a 6) and restart the connection
it may help or it may do nothing or i might be wrong

wifi good..no data

Vegan gb 7.0. I can connect to the web just fine, but I can't download anything and anything needed for a data connection wont work. It's an intermittent problem, my wifi status bar will be white when it doesn't work and green when it does. Pershoots latest kernel.
I've noticed the same thing with the white icon vs. green icon when using wifi that is filtered/proxied. Like using wifi at a local coffee shop where you have to agree to the terms of use. You are connected to the access point but not to the outside WAN.
I think your connection issue may be more network related than device related.
What type of wifi connection are you using? Is this a personal one or a public one? Do you have access to the router's configuration? (Linksys web interface is 192.168.1.1 by default, for example.)
Personal wifi...psa2. I put my tab to sleep last night not working ...now it is. I've restarted before and it didn't fix it. Belkin router.
Yes this is happeningto me.....so when thewifi is green I can download but when its not I cannot download..... I did nothing itjust goes back and forth from time to time ....anyone know how to fix???
Network troubleshooting.
To the best of my understanding, this occurs when you have connectivity to the wireless access point, not to the internet itself. I think it turns green when it is able to contact Google services. Generally, this would mean that your wireless router is either not reaching your internet service provider (ISP), or there is a proxy not allowing your device to use the access point as a gateway to the ISP.
If you're on a public network, like Starbucks, McDonalds, etc., you may need to agree to an acceptable use agreement. I've found I need to use the default browser for this.
If you're on your home network, the next time the icon is white, check the following things.
Are any other devices on your network having a similar problem?
Does your modem have power? and are the lights indicating trafic?
Can you access your modem's web interface, and run any diagnostic tests to be sure it's reaching your ISP? (You may need to contact your ISP for further instructions.)
Is your router able to contact the modem?
To determine if this is the case you'll need to trouble shoot your router and its connection to your modem.
(The following are some defaults.)
Model IP address user password
Linksys 192.168.1.1 admin admin
Belkin 192.168.1.254 admin "blank"
Netgear 192.168.61.1 administrator password
I could have mixed up one or more of these, but it's one variation or the other.
The info may even be on the bottom of your router.
Once you've accessed your router, make sure it's getting an external IP address from your modem.
Let me know if any of this helps. I'll try to get back on later this evening. Leaving work now.

Galaxy S2 is able to connect to wi-fi router but can't access Internet ??

hi,
I've linksys wi-fi router model WRT54GH in my home & it has a good amount of signal strength to cover entire area.
My recently bought galaxy S2 is able to identify linksys wi-fi access point & connects too with the IP assigned to it, also at wi-fi settings connected being displayed.
Now when I try to access Internet (any url google/FB), it doesn't connect at all.
I tried almost everything about router configuration, restart etc. but with no success
can someone plz help on this ?

In my case the problem was with frozen "WiFi sharing" in combination with juicy defenders "Location" fearure. It seems such combination is dangerous. Solutin (in my case):
1. defroze
2. remove all wifi networks
3. reboot (for "clean" frozing)
4. make WiFi sharing frozen
5. reboot again just for fun
Try to check your router's MAC address restrictions. In my router, as security, I have to add MAC addresses of each device to share internet. They take IP's, connects etc. but does not have accesses to internet
as above, check that there is no MAC filtering set up.
one other thing it may be is the security settings, if you have a WEP Key to access the router it may need the Hex conversion of your key depending on what level of security you have (64bit or 128bit for example)

Try setting up a static IP address for your phone, I presume your network is a 192.168.1.0, go into router settings and LAN setup, give your phone the address in a static DHCP assignment of 192.168.1.5, or any other address in the same subnet your in. Some SGSII's have problems with dynamic DHCP for some reason, some NS had the same problem too,

I have a similar problem and I fix mine temporarily by turning my wifi off, then in wifi settings > advanced, I change wifi sleep policy from 'never' to 'only when the screen is off'. However I have to do this every time I want to use wifi so it can become quite annoying sometimes.
So I can get through however only for a short period of time as it seems as long my Galaxy S2 keeps turning off my wifi even though it's on :/
I had exactly the same issue on Linksys E4200 with my laptop, could connect to network, even to router's attached storage, but not to internet. Restart helped
On SGS2, I couldn't connect to the router at all at first, but fixed this by switching from WPA2/WPA mixed mode access protocol to WPA2 private. But I guess this is not exactly your issue.

Yes, you are right this is not an issue for me.
In fact my SG2 being assigned with an IP address from 192.168.1.xx subnet.
Also at a same time my laptop connected with an IP from same subnet able to ping SG2.

My SG2 being assigned with an IP address from 192.168.1.xx subnet.
So I think IP addressing may not be an issue.
Also another thing I tried was, at a same time my laptop connected with an IP from same subnet able to ping SG2.
So wi-fi router may not be an issue here, whats say ???
Even I am facing the same issue at my office network. I am able to connect to the wireless network but if I try to access any app I cannot browse. This is really frustrating looks like some issue with the modem drivers.
I was able to browse on another wifi created virtually by mobile tethering. This looks like a major bug with the current firmware. Another interesting thing to note is that the Wifi network has a hidden SSID and uses WPA2 auth scheme.
I have seen a Galaxy S able to connect to the same n/w without any issues.
Has anyone figured out a solution to this one ?
Hi, thanks for your reply.
I am yet to figure out a solution for this
Even I am also agree on the probable issue with modem driver.
I've D-link modem.
Are you aware of anything about this modem that can be reconfigured to get this worked ... ?? pl let me know
The wifi router at my office is Cisco Aironet 1200 Series, anyone else facing this issue ?
I'm having the same problem at work connecting my SGS2 with v2.3.3 Official Firmware (customized for Orange service provider) to a Cisco Aironet 1130 AP. I can see that the Galaxy authenticates with the AP correctly and gets IP from the DHCP server, but it cannot send or receive any traffic, although the phone stays connected and authenticated. At home, I use an Atheros based Fonera with DD-WRT without any problem.
As I'm the company's network administrator, I will try to further investigate this problem, but it seems like some kind of incompatibility between the devices or misconfiguration ....

try turn off the wifi, turn off the mobile data and turn on the wifi again
It seems the SGS2 sometimes has problems with DNS.
Try a static IP and use 8.8.8.8 as second DNS server, which is a free Google DNS server.
This fixed MY problems
I rooted my SGS2 and voila wifi worked at my office finally I have been able to find a solution.. love my SGS2 the Beast...
I'm having this same problem..
I think I've tried all the solutions above, but one (Sorry - noob question):
Rooted?
is there a firmware patch or something that I should know about?
Anyone got any other ideas?
ETA:
I can connect to hotspots (DHCP) and at home (Have to set it to static tho)
No internet
AP works - Laptop and i8910 (had to set static and advanced settigs etc). I've rebooted it a few times, set DHCP on and off. DHCP seems to be running on the router

This is an issue with SGS2 with wifi server using authentication protocol TPIK, if you use AES as encryption then it will work without any issues.
That should be a setting in my AP? I can't see it...
If I get a new non-crappy AP is that likely to solve my problem?
ETA:
Ah - that's a WPA thing? Mine only seems to do WEP - is that right?

S3 can connect to WIFI but no Internet

Hello everybody.
Since last saturday i'm testing a Galaxy S3.
I want to test if everything works properly before buying it.
I have some problems deling with the WIFI stuff.
I gave him a static IP (192.168.1.15), configured the gateway as the ip of my router (192.168.1.1),
the network class is 255.255.255.0 (network prefix = 24), the DNS points to the IP of the Router (192.168.1.1)
It connects without problems. form the S3 i can ping any device in my network and from other devices i can ping the S3.
I can connect to the configuration site of the router and from the page of connected devices i can see that the S3 is connected
with the correct ip and also the MAC adress is correct.
And for now everything is fine.
Problems raise up when i try to surf internet. The answer is always "Page not found"
If i open the browser and try to navigate to google] the answer is "Page not found". Same for any other site i try to connect with.
I cannot ping external adresses from the S3. Only the ones inside my LAN.
On the same LAN there are 3 laptops, 1 IPhone, 1 TV, NAS NETGEAR , home automation screen, all connected in WIFI.
All of them configured in the same way. (static ip, gateway=ip router, dns = ip router, network class 255.255.255.0),
And they all access internet without any problem.
The network is protected with WPA2/PSKey, encryption AES.
I tried to configure channel with WPA, WEP, without protection, but no changes.
The S3 connects to router but does not connect to internet,
I also tried to make it point to a public DNS 8.8.8.8. No WAY!
Works for other devices.
I tried to reset S3 to factory parameters, same thing i did for the router.
I reconfigured everything from scratch but no result.
I do not have any filtering based on IP or MAC adress on my Router.
I tried with DHCP, with reservation of IP adresses or without reservation. No change.
Other devices can access internet. S3 does not.
I have to say i'm quite desperate.
If you guys have some good ideas to solve or diagnostic the problem i would be grateful.
Cheers,
Fabio
I get that around my office as I walk around, I find that when I change AP in range my internet connection drops. I have to constantly disable/re-enable WiFi.
Even around my house, I have the handset to WiFi always on, yet when I wake up in the morning the internet connection is not working yet there is an IP. I couldn't be bothered to telnet to port 80 etc., but I hear that the Jellybean update will resolve this issue.
Same problem

Android Location Issue

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.
