Wifi location not accurate - G1 Q&A, Help & Troubleshooting

Not really a phone issue, I know that it's with either my router or my modem (not sure how it works exactly). When I disable my GPS and put my phone on Airplane Mode (but leave Wifi on) and go into Maps, my location is incorrect. It is showing me at my old house (a few hundred miles away from where I live now). How do I go about telling whatever tracks where my router is, that it's not there anymore?

You said you turned the gps off? You have to have gps ON..lol. It is probably showing you the last location it was turned off. So turn the gps on and make sure it is receiving a signal from the birds(satellites). You cannot get a gps signal with gps off and it will not show a correct location. Wifi is for downloading the maps to show where your gps location is.

Wifi is also for location. Hence, Wifi Location. Go away until you understand the actual question.

Its not an accurate location tool, GPS is accurate the other is not.
If I turn GPS off I am usually in the middle of a field quite a way from my house, it uses the network, not WiFi (IIRC)

Google Maps not accurate

As above, I have already turned on GPS but it's still few streets away.
Any help on this?
are you out doors? also what rom are u using, some of them have broken/messed up gps
Is the GPS icon solid or blinking?
If it is blinking, then the GPS has NOT LOCKED ON!!! Means that your location is based on the CELL TOWER you are connected to!
Just wanted to throw this in...
People often have the gps off but the "Use wireless networks for my location" feature turned on....which will give you the location of the nearest cell tower to you....
If you enable gps from location...you will get your exact position...unless you are using a custom rom with buggy gps...and there are a few of them out there.

[Q] could wifi be the problem with samsung captivate's gps issues

anyone else notice that when using the Samsung captivate & navigation that is recommends turning on WiFi. it doesn't make sense, but i notice it makes a huge difference in speeding up satellite connection time with WiFi on.
could this be the issue with the GPS??
please confirm this.

This is not a fix. Turning WFi on will help give your phone another source to determine your location. The key thing here is that WiFi cannot determine your location as accurately as GPS can. If you look again, you'll probably see that your phone will "lock" onto your position much faster, but it's probably not going to be accurate enough to be usable.

you must have read the title before i edited it.
im not using the WiFi as a location source since i don't have any WiFi internet on the road.
but i notice that the GPS locks on quicker than without the Wifi on.
my nexus one never suggest to turn on WiFi when using navigation
Its not necessarily wifi based location but it can use wifi to download gps data. For a date lock. Its just a suggestion, I don't see why out would make a difference with out a wifi signal.
I prefer to not have network location or sensor aiding enabled. Sensor aiding really doesn't work. Made my my tracks results erratic. Network location gets me within 2 miles, not exactly good for navigation, having it on only allow something to fall back on of you lose gps signal but the whole process of the phone switching from one source to the other and back again takes to long. Keeping network location off forces it to only try to get a gps lock and in my opinion works better.
As far as wifi, if you believe it works better that way then do what every you think helps. It really should only download the data and once it has it it is done with wifi un till it needs new data which usually won't be for several hours.

[Q] WiFi Only GPS Questions

I was curious as to why there is a button in the notifications menu to turn GPS on and off. I started to look in to it and discovered that there is indeed a GPS chip in the wife only version, or there seems to be anyway!
My question is, what does that chip exactly do? Does it only pick up your location? I can't seem to find any places around me with wifi off. I'm assuming that means all the map and location data is delivered over the internet through 3g or wifi. Is there anyway to use my device as I would a regular GPS device? I know it has all the features but can they work through the GPS chip like they do in a GPS device? Or is there anyway to get this to work?

Ok the wifi is mainly just for accessing networks either open or via ssd and password. You can also connected with mobile AP if your mobile has this option.
The GPS on the other-hand is for mapping and location based services like navigation etc (you can use copilot and several other gps based apps with the P1010). Some of these apps will also piggy back any Bluetooth and or wifi connections that are available for further triangulation if needed. So if you have any apps like various weather and navigation then the GPS is required (but also your location can be shared via your wifi and opt in to give this info through google).
Hope this helps

you can find your location via wifi, enable your wifi and turn gps on, you'll find your coordinates, but not that accurate compare to 3g

[Major Bug] Wifi Always Scan breaks Location Services

Hello everyone.
I just wanted to get your attention on a major Android OS (Kitkat) bug in the interaction between Wifi -> Advanced -> Wifi Always Scan and the Location Service. Clearly the bug doesn't happen every time, but sometimes it does, and obviously I'm talking about stock rom / kernel / no root / locked bootloader.
Althought I can't prove it, this might also be the cause of the current GPS / Navigation issues, currently being reported here.
What makes me link this to that issue? Because when Wifi Always Scan bugs out, it prevents my phone to acquire a location even from the 3g network.
That would explain why in that thread many people report that they could navigate with Device Only, which doesn't use 3g or wifi for location, but they had major issues with High Accuracy, which uses all three sources.
Please take a minute to star the issue so that Google will hopefully fix it faster.

Just turn it off, all it does is waste battery anyway

Thanks for your useful contribution.
It doesn't waste battery, it saves it. It enables to use the wifi location using a lower power state of the wifi chip compared to actually turned on wifi (which is also more accurate by miles than 3g location, works indoors in clubs where there is no 3g or gps signal, and not as battery expensive as gps location).
Also, people use that option for many things, I for one use it in MANY Tasker tasks flawlessly, whether the alternative (wifi periodic toggle and polling) would rape my battery.
Wifi automatically Turned off. Built in feature?
I kept my wifi on, and the had not used it basically just left the device in the room and had run off.
When I retured, the wifi was on in the power control widget but the wifi signal indicator icon in the notifications bar was absent.
is this normal/intended?
My wifi / internet connection is weak but continuous and my device is about ten to twelve feet away from the modem / router.
Can anybody help?
Although I have not a Nexus 5, my problem seems to be the same. I'll tell you if perhaps serve as any indication.
In my HTC EVO 3D, I've been running since the summer with CM10.2 (Android v4.3.1) with location mode set to "Network & WiFi" and "WiFi Always Scan ON". During this time the location was very accurate, location history left a fairly detailed trace. In Google Maps, was located immediately, as in Google+. If activated the GPS, even better. Summarizing, 0 issues with the location.
On January 1, I decided to upgrade to CM11 (Android v4.4.2), I set my location mode to "Battery Saving" & "Wifi Scan Always ON". During the first 10 days everything was perfect, the location history trail was so detailed as CM10.2 and battery consumption a little better. Google Maps and Google+ also positioned themselves almost immediately. Suddenly, on January 11 the location seems to stop of using WiFi networks and began guided only by the Network Cells (being rather more vague). Also when for some reason failed to position (being out of range of Network Cell), the phone started to not enter Deep Sleep Mode and the battery started to discharge at high speed. Google Maps, Google+, 1Weather ... were unable to obtain the current location or showed the last known location of hours before. Rebooting the phone sometimes temporarily solved the problem, but sometimes not.
I tried to change the placement options; abroad, with "high accuracy" mode, the location worked well, but indoors the GPS was not able to find satellites (logical) and still the same problems. I enabled and I disabled the location, nothing. Factory reset, no change.
To rule out a hardware failure, I returned CM10.2. Everything about the location worked smoothly... Return to CM11, again the same problems.
In short, my impression is that this is a software bug, as in versions prior to v4.4 Android location "Network & WiFi" + "Scan Always ON WiFi" works correctly. Moreover, not only occurs in the Nexus 5.
I have marked with a star your ticket.
I'll keept testing.
I get this problem when I use tether with WiFi always scan enabled.
When I disabled tethering, I have to manually enable WiFi to fix the location reporting issue.
With WiFi scanning not enabled, I do not get this problem

I think I have similar problem and I really hope smbody can help me.
On my stock nexus 5(4.4.2) wifi location don't work in google maps and ingress, when I turn it on instead of gps location.
But in other apps wifi location works( yandex.maps, 4square)
Only reboot helps
Hello again.
I just updated Google Maps to version 7.6.0 and Google Play Services to version 4.2.39 and all the problems I had with the location are gone, everything is okay again, as it did in CM10.2. So it looks like it is confirmed that it was a software bug.
Sorry, I know this post is quite stale, but I came across it doing a search about this very same problem I've seen on my LG G4 (stock). I have a Tasker task that uses WiFi near state and I use the "Allow Wifi scanning..." option in my Advanced WiFi settings. Whenever I would use WiFi tethering and then later turn it off, I noticed my Tasker task would not detect the WiFi networks it was supposed to. If I turn the "Allow scanning" option of and back on, or just turn on WiFi altogether, it starts working again.
So, after more than a year and a half, and on a newer version of Android and it still doesn't work right. Who knows; maybe it's a Tasker problem.

Get Location command woes...

I made (from various info i found on the net) a profile that can look up the location of my phone and return the data to another phone via SMS.
In this SMS i added some extra data like battery state, cell id (if it can find some), signal strenght for those cell's, wifi signals in the neighbourhood of the phone etc...
Quick look on what it does.
SMS received with certain text.
Turn on Wifi, GPS, Mobile Data
Get a location set to ANY with "keep tracking" enabled.
Store the location and other data in variables.
Turn Off Wifi, GPS and Mobile Data
Send a return SMS with the data found in the variables.
This all works fine except for the location which only works when i have good signal, either GPS or Mobile.
If the phone is in a place where the GPS or Cell signal is weak, it returns the latest location for which i found a good signal instead of the actual location (even if it found cell towers in my current location and i'm using NET instead of ANY in the Get Location command).
On the last tries of the profile in a more covered location i get a return with an old location but do get a cell ID return with a weak signal so it should be able to locate the phone and determine location data instead of using the old ones. If i then go out in the open, it works right away as it should. I can check this because the Cell ID returned are the same when i get in the open only with a better signal.
However, if i use a location app or the Samsung's Find My Phone, in general it locates my phone even when GPS or Cell are weak (not always but often).
How do they do that and and what's their secret?
Found the answer to my question:
I only used the %LOC variable but that only returns a location obtained by GPS. If the GPS signal does not exist, it will return the last known location instead.
By changing to %LOCN to obtain Cell Tower location, it returned a true location instead of the old GPS location.
Found out that my answer didn't work out.
I'm in another location now where i have both good GPS and Cell coverage but it olny updates the GPS retrieved location, the Cell location is still the old one from my previous try although the cell tower info has changed and is one very near me.
