I moved (with my WiFi router) from Maine to Texas. My Xoom is convinced that that the WiFi still signifies that I'm in Maine. The widget for the Weather Channel keeps showing me the weather for Portland, ME. Also, whenever I open Google Maps, it jumps to my old address before going to the current GPS location in Texas.
I assume there must be some sort of cache that associates a given WiFi MAC with a location. I tried deleting the WiFi association and then adding it again, but that didn't fix the problem. So my guess is that I need to clear that cache (if it exists).
Any help would be greatly appreciated as this is a quite annoying problem.
Oh, I forgot to mention. If I turn off Google's location service (Location determined by Wi-Fi) (in Settings-->Location services), this fixes the weather app, but Google Maps still jumps to Maine until I get a GPS lock.
I think this is in Google's cache - they know your wifi was at your old place so that is where everything starts. I tried to look for a link from Google to "reset" your location data. I couldn't find it. I will post back if I do.

Found a similar post in a Google forum.
I can't post links yet so...
open google - search for "google reset wifi location" and check the first link.
What about changing the name of your wifi - the network name will change and then Google will update the maps (maybe).
Found another post about google latitude - might be able to reset location?
I changed the WiFi name. I'll post back later with results after I see if it works over the next day or so. Looks good so far though.
I thought it was going to work. It still showed the correct location last night (about 20 hours after the change), but it's now (40 hours after the change) messed up again. Very strange that it would work for that long and then revert to the previous behavior.
None of the links in the search result referenced by da_beast work anymore. Unfortunately it's a 2 year old thread. It does seem to match my problem exactly though, so thanks for finding it.
I found another thread that says that, by leaving GPS and WiFi on consistently, it will eventually get fixed.
Here's the oddest thing though. It screws up my Xoom, but not my phone (HTC Evo Shift 4G).
Current plan: leave both phone and tablet connect to the WiFi with GPS on and see if it helps.
I'll update for anyone who might be having the same problem as I see what happens.
Just by pure coincidence I saw an app on the market today called Location Cache by REMYDEMY. I have never used it, and have no idea if it works; but, it has positive reviews, and seems to do exactly what you're looking for. Let me know if you do decide to try it, just out of curiosity.

That might do it - I tried it just to see what it does.
Lost track of this thread for a bit while I was dealing with work stuff and installing a washer/dryer set.
Anyway, the upshot is that leaving the GPS on along with the other things I tried seems to have fixed it. I haven't had problems in at least five days.
Since I don't know what exactly worked, here is a list of everything I did (Note a number with a letter means I did these these things basically at the same time or several times that were mixed together):
1) Left GPS on for the Xoom (WiFi, no 3G)
2a) Accessed Google Maps multiple times on the Xoom when the Weather Channel app showed the wrong location
2b) Traveled to a family member's house with WiFi that showed the proper location on the Xoom multiple times
3) Changed the AP name for the router
4) Turned on GPS on my HTC Evo Shift 4G
5a) Accessed Google Maps multiple times on the Xoom when the Weather Channel app showed the wrong location
5b) Traveled back and forth with the phone only (GPS still on)
So conclusion, it's fixed.
My guess is that it has to do with multiple GPS location fixes while connected to the router. I don't think changing the AP name had anything to do with it, but I don't know for sure. I do think that having multiple sources (phone & tablet) helped, but I can't say for sure. It could have just been the number of GPS/router connections from the tablet.

Dear XDA-users,
I have an LG E900 in Sydney Australia on the Optus Network, which has been fully updated to Mango (and then the tethering update). (also chevron unlocked). Its set to Australian region and its an optus rom I think (or whatever comes with the phone...purchased in Australia).
I have a strange issue with my Bing Maps (standard one that comes with the OS).
When I try to "find directions" when I am using my 3G data it comes up with one of two error messages:
1) No Location Information: Bing Maps can't find your location at the moment. Try again later. (but it has found me correctly when I click the "me" button grrr)
2) Bing maps cannot reach the internet. Please check your 3g or wifi connection. (but I am completely connected to the internet).
So I have done some trouble shooting and both of these errors are illogical or incorrect.
first of all, when I click on the "me" circle it finds my location perfectly (scarily so).
Also I scroll around the map and zoom in and out and bing maps is clearly reaching the internet as it is constantly clearing up the resolution. Also I can go to use internet explorer just fine.
I have installed Nokia Drive and Bingle Maps and both of these applicaitons work perfectly for giving me directions on 3G.
Now the kicker, when I am at home and I connect to Wifi bing maps direction does work, but directions on Wifi is essentially useless for me, as its when I am out and about that I could really use it.
One last thing I tried finding directions on 3G data where I put both places as a fully written out address (as opposed to "My Location"), and it still doesn't work BUT if I go to search for an address (not directions), then it finds it straight away.
Is there something I can do to further trouble shoot or fix this error up in anyway? I really want this to work ...
I guess no one knows how to help me.... in that case does anyone know how I can "reset" or "re-install" the maps program or something to trigger it back to proper functionality.
also this is a bump to the first post haha.
Weirdly worked out what was wrong...but not why. In any case my issue is reolved now...
The APN from Optus was 'yesinternet' (as it should be). I had a friend who suggested changing it to just 'internet' like most carriers and see what happens. Did that, restarted the phone and instantly it was working. All other 3G dependant apps like email, explorer still works just fine.... so there you go...
Can anyone explain that?
Its fixed so mods you can put a resolved tag on this one if required.
Interesting. In the states, my 4g stopped working for like 1 whole day and i couldn't figure out why on att. what i did was manually put in the apn settings i found on the internet and it immediately started working. next day set back to auto everything was fine. Think my carrier was messing with settings but wouldn't admit to it.
Handy to keep those apn settings around in case of emergencies. maybe the original uses a proxy that filters out bing and the "internet" one does not?

This makes sense I guess, but pretty poor choice for Optus as they are the official seller of this model of phone in Australia.
Im currently having a problem which i reckon no one else has....When im conected to wireless at home on either of my 2 routers the location changes to Tianjin HK.Problem is i'm in Cornwall UK.It can be pretty annoying if i install a fresh rom and et my alarm before changing time zones!Here is my phone screen...
Here is my Routers time zone settings (i use 2 tenda routers both have the same settings)
If ANYONE has ANY ideas i would love and cherish them.
Hello mate you got really wierd problem. Try to clear cache for htc sense and weather and clock application. let me know if it work>>>>>>>

---------- Post added at 06:09 PM ---------- Previous post was at 05:33 PM ----------
WiFi location determination is done automatically, so there's no way to manually update a location, but it does help to expedite the process if you connect with your sensation to your router while your GPS is turned on (and has a clear view of the sky) - over time, the WiFI location should be more accurate as google update their location database.
wrong locations could happen for several reasons. If a location is accurate but named incorrectly, Google may not have been able to correctly identify the location by its latitude and longitude. If you use cell ID (cell tower) or WiFi (wireless) location detection on your phone or computer, Google may have wrong or outdated location data for that particular cell tower or WiFi access point in location databases. Please keep in mind that coverage for both Google's cell ID (cell tower) and WiFi (wireless network) location databases varies by location and is not complete. They are always working to improve both coverage and accuracy over time. You may also delete any individual wrong locations from your history at any time by selecting the location and deleting it from the google dashbord.

Only thing I could think of is that your ISP has their DNS server there? I don't think that there would be anyway to fix that though.
That could be a possibility but i dodnt have the problem with my hero or magic? Wifes Wildfire S does the same :/ ill try gettign gps lock but we have thunder atm so will try tomorrow.Thanks or the answers guys
Similar Problem?
Hi,
I've maybe a similar/related problem; my clock is getting out of sync. During the day it's not happening. I coudn't determine the reason yet, but it happens every time my wireless and GPS locating is enabled. I'm getting wrong location information almost always. But if I disable GPS location and leave only wireless enabled I get correct location information. Now I try to figure out why this is effecting my system clock if in anyway possible. I don't think this
is a insertcoin bug, because I had this on ARHD 6.x as well. I already cleared clock app cache, deleted the alarm and created a new one. Does anyone else have/had something similar?
The stupid thing is I'm getting late to work and need to use another
method to wake up on time.
I'm on ICS 4.0.3 (insertcoin 4.5.4) base Sensation with Ultrasmooth Rosie applied.
I am currently using Insertcoin 4.5.4 also but i happens with every sense rom i use.And its not just my ISP, Happens with any Internet connection i use "WIFI" and annoyingly changes my timezone.Only way i have found around this is to set my location manually.Weather in London is a tad different to here in cornwall
Strange that you are on Insertcoin as well, maybe we should post this question in the ROM post of insertcoin and ask others. Unfortunately I can't as I have not enough posts yet
As i said in my last post it happens with all roms and i am ALWAYS in Tianjin
Try changing the name of your Wireless SSID. I have a wireless router that I use for travel, everytime I connect to it, it says I am in Colorado as I used it over there for a week.
This will force it to make a new entry in the Location DB and associate it with your current location, it could be that it is matching your SSID with someone in China
Tried everything, Finally my solution was to take
/data/data/com.htc.provider.weather/files/WP_0409WWE.db
Edit it in a SQL Editor and add my current location! Didnt like me renaming the United Kingdom to Bonesville though
I've got a screwy situation I'm desperately seeking a resolution to... simply put, we moved, and since then my Galaxy S2 (AT&T) pulls location from wifi when connected to it, everything within the phone keeps showing up that we're still back home, 30 miles away in a different state! But simply turn wifi off and then use 3G for location, and from the same spot in the new house, everything begins to work normally...
Now here's the twist - only on certain roms does this happen. Right now, I'm running MIUI 2.3.7, build MIUI-203090. Right now, on THIS rom, everything is working as it should... wifi is on, phone connected, showing all the correct information for the correct area... by changing roms, with all the same settings selected, the phone begins showing up back in the former location, and I begin to boil. I've reset the router back to factory defaults, and the same problem exists... I'm convinced it's a router issue.... I have an HTC Inspire that I had until 2 weeks ago when I made the upgrade... I broke it out and used it to test... and I can confirm that, on certain roms, even with a totally different phone, the SAME problem results because its connecting wirelessly to the same router....
Any ideas??
I assume that you are using the same router as previously?.. A router does not necessarily re-ping its location on a regular basis and so you may very well need to update your location in the skyhook database..

Never heard of this before - will try it...
If you have Google location checked it may be using the known location when it was first detected.
Change your router wifi name. Then it may not know anything except through GPS.

I tried the skyhook option, but it's not real clear - either it could take affect or could take up to 7 days - ?!??
The router's wifi name has been changed - and even went as far as to restore it back to factory defaults... STILL the same result... I'm absolutely confused.
this issue is not uncommon.. eg. my mobile hotspot shows me at home no matter where i am in the USA... a router is part of infrastructure and so is a fixed location... if not then the skyhook database would not even be required.
For any changes to take affect you will need to power cycle the router... and yes, a free service may take time to resolve itself.
you're welcome
p.s. nowhere anywhere on the web is a router referred to by name.. it has a unique mac address..it is this address that is tied to your location so change all you want.. but until the db is updated you will live 30 miles away

"until the db is updated?" - I'm sorry, can you be more specific?
I have a Belkin n450+ router... how would I accomplish this?
I had been powered off all during the move, well over 24 hours - I'm confused about how to go about "clearing the db" -
if you have reported the location change to the skyhook server, you will have to wait for them to update their database (db..sorry)..
You have tried a reset, the only other suggestion other than to wait is to restore the factory firmware to factory settings.. you may need to update firmware after this and will need to reset and configure your network, but its an idea..

Just did a search for this problem and found this thread. Is this still the best solution?
Google uses many methods for its location, WiFi, GPS and Cell towers.
Remember that Google Street View car that travels around. It also tracks location and if it sees a WiFi signal it records the broadcasted name and location. If you use a Google service, phone or PC Google tracks the WiFi access point name. If it has a record of that name if knows your location. Otherwise it only knows your IP address is within a certain area of a city.
So, Google knows your WiFi routers name is at a particular address/location, then you move. Google doesn't know you moved so it continues thinking you're at your old address.
Changing the Routers WiFi name and a new IP address forces Google to relocate you by using GPS and other WiFi Hotspots it sees near you on your phone. It will then associate your new WiFi router name with your new location.
Basically but more complex than that.
Hey everyone,
I'm experiencing a couple minor issues with my MyTouch 4G Slide and wanted to see if anyone had any input.
First is the weather location... when I am at work my phone's weather location always gets all weird. It happened with my G2 (before this phone) as well. On the G2, it would show my location as in Japan. With the MT4GS, it shows as Denver CO. It updates when I leave the building, but it is still frustrating for numerous reasons. First, the time on my phone switches to Denver's time zone while at work. It throws me off whenever I look at my phone. Also, after I leave and the location updates, it doesn't update the time zone. I have to go to Settings -> Date and Time, and uncheck and recheck 'Automatic' for it to switch back to the correct time zone. Finally, while Maps will read my location just fine, other location-based apps seem to be thrown off as well.
One other question is about the hardware keyboard. I have Prediction turned on in settings but it never works. It's nice with the hardware keyboard because I can skip the alt+ keypresses for punctuation and it inserts automatically, and it will capitalize I, etc. If I'm not mistaken, this hasn't worked since the recent HTC update that moved us to Google Play Store.
If anyone has fixes and/or other info about these issues, I'd appreciate your input! Thanks so much.
Are you connecting to your work's wi-fi automatically when you are there? It could be that the location information (which would affect weather and time) is using your IP address info. I know when I connect to my wi-fi at home, it will alter my location to a nearby suburb.

I wish! Our WiFi doesn't even show up on my phone... they must have the SSID hidden. I think it's because the building is older, and it must have lots of concrete or something because radios, cell phones, etc don't work well in here. Mine only works because my desk is right by the main entry door and a few windows. I'm assuming that the GPS signal could get thrown off by that as well. I'm just hoping since Maps can locate me that maybe I could fix the rest of the location-based services.

It may not even be getting a GPS signal, instead relying upon the location data of the celltower you're linked with. I've seen the location info being off by neighborhoods, but not to the extreme you've mentioned.
Uncheck the automatic update, then it will stay in the right timezone.
Also, I use swiftkey x, it has the best word prediction, and works great with the hardware keyboard.

Thank you for the recommendation! The app is downloading now and I'm already excited because of the amazing reviews it got. I'm sure I'll love it. I was hesitant to uncheck the automatic setting because I want it to sync the time... but now that I think about it, once the time is set from the network... why would it need to sync? Unless I do a battery pull or something.
Hi guys,
I run PA 4.4 for like 10 days now. Since a week ago I have strange locations in my Google location history - constantly, when not moving - and rather accurate when I am outside (maybe has something to do with the wifi connection when stationary at home or at work?)...
One interesting part of it is: the first days of my new PA experience everything was fine. So probably it does not have anything to do with it. That first day I had the issue my phone crashed earlier while I was outside and I had to do a reboot. Maybe some settings were changed during that!? Or... maybe it doesn't and it's just a coincidence after some apps where updated (Google Search or so)...
I tried quite some settings to figure out what happens here - and it is not trivial - to my mind:
I did another clean install of the ROM; had the same issue again
I changed between "high accuracy" and "battery saving" mode in the location settings; no change
I went to the developer settings and unchecked "accept mock locations" (is that how the option is called in English?); no change
I have a Nexus 10 also running Android 4.4.4 and started to record my location history from that device with different settings: all are fine and accurate! When I record from both devices I can actually see my history jumping in 5-minute-mode...
Any ideas, any suggestions?
Please...
Two more findings, which make this issue even stranger:
When I move in the house - e.g. 2nd instead of ground floor - I get different locations, some 100 or 200 meters away, but both far from home.
I turned wifi off for one and a half hour - that resulted in perfect locations!! Locations were inaccurate after turning wifi on again...
What is wrong here?? So I get more inaccurate locations when connected to wifi!?
i always run straight gps and never wifi. imo its a conflict of interest.
gps is dead accurate, so the only time you could benefit from wifi is when you are in a building with no gps signal, and frankly, why would i need 100% accurate gps if im already in the building.
again imo, what is happening is, it can only reference wifi that it knows the exact location of. it has no way to tell how far from that wifi you are, so its guessing based on a limited gps signal and known wifi points.
i think its a waste of battery to be scanning wifi points all the time any ways, unless you have a constant use for it.

Thank you for the answer! And I sort of agree...
But the question is:
what did change that day when my location started to be different? I never had problems for more than two years of using the location history. Even after moving in April everything was fine with the wifi locations. I get one accurate reading like every one to three hours - so the location jumps from time time. Why is that? Is that a gps reading?
Plus: how could I change the settings? The only thing I can chose from is: "battery saving" (cell towers and wifi) or "high accuracy" (the same plus gps). I selected the second option but obviously still the Google location service does not really use it. When I turn off wifi it can only use cell towers plus gps... but obviously I want to be connected to the wifi when being at home.
I can't say why it started acting up.
If you use WiFi you are kinda stuck.
I only have GPS on and denied anything that wants to use WiFi for any reason.
I don't know where the option is found, but I remember it asking if I wanted to use WiFi to help results or something like that, I chose no.

I guess that option is the "use wifi for location detection although wifi is turned off" which can be found in the wifi advanced options. But I turned that on and off, no change.
But one more test from myself:
I let wifi on but disconnected from my home network. The result is: accurate locations! So the problem is not the wifi itself but a connected wifi!? And it is not only the home network because I had the same issue at work.
Plus: we just had a thunderstorm, that could have been the reason why cell towers and/or gps reacted differently: my location was at some new place about more than a mile away. The worst thing is: accuracy of that location point was about half a mile -- which means: my real location was not inside the accuracy cycle (that blue cycle when using location history)!!
The accuracy cycle is always very small when I get the real readings at home and always about half a mile in radius when somewhere else...
that is basically the problem with using wifi to help. there are too many variables. location needs to know the location of the wifi, but then there is a broadcast radius that decreases accuracy. there is also the question, what does it do when you are connected to a wifi it doesnt know the location of?, that could cause inaccuracy. maybe it makes an uneducated guess, who knows. there is also the issue, what if it thinks it knows the location but its actually wrong?
the list of possible scenarios could go on and on as to why it isnt reporting correctly.
the only way to truly know why it is wrong is to find out why exactly it thinks you are where you are when its wrong. there has to be some exact source of information its using to base your wrong location on. unfortunately, i doubt there is any way for the common user to get this information, let alone take corrective action so its not inaccurate in the future.
wrong locations only when wifi is connected, only on one device
OK, what do we already know?
I have the problem for some 8 to 10 days now. Never had it before, only have it on one device.
Maybe a coincidence but this behavior started on a day where my phone crashed and I had to reset.
I made a clean new re-install of the PA 4.4 and recently received the update to PA 4.42. There are no changes in the behavior.
It is only my phone (running ParanoidAndroid based on KitKat 4.4.4), my tablet (Nexus 10 running stock KitKat 4.4.4) does not have this problem (so it's no wifi relocation because of moving or such general problem).
I have the problem with more than one wifi! Have already seen these false locations when connected to the home and when connected to the work network. Problems with both networks started the same day...
Wrong locations are constantly there when my phone is connected to a wifi.
It's not always the same location, sometimes I get different readings, but it's 90% a position ~430m west of my home.
The correct locations have high accuracy (a few meters), the wrong locations have very low accuracy (~1000m or even more).
When I start Google Maps (i.e. probably when the phone uses gps) I can see my position moving towards the correct location.
When I switch off wifi or when leave wifi on but disconnect my phone from the network, then I get the correct location constantly.
Roughly every 1 to 3 hours there is one correct location within the list of false locations.
I tried virtually every combination of settings, "high accuracy" and "battery saving" for the location service, "no mock locations" in the advanced developers settings, "use wifi for location detection although wifi is switched off" in the wifi settings, ...
Is there some sort of cache that might be corrupted!?
Is there a possibility to force using gps?
What else...

I guess you shouldn't rule out that it is an issue caused by the ROM some how.
On my phone I can force it to use GPS only, I have the option anyways.
Under location I have device only or something like that, it says it only uses GPS when that option is selected.

I thought about that, too. Means to installiert something else, CM11 vor so...
There's the option "device only".
That option does not record the location history, afaik.
Which means: Google Now does not work. So that's not an option...

so i did a little test today on the way home from work, as i took a different route than normal to avoid traffic.
when i started "maps" i had to allow google location services to navigate. so im pretty sure you can use device only as long as you allowed google location for apps, as it said something about my google now functionality when i turned it off after navigating.
last week i navigated a 3 hour trip, on a different rom, with no issues. today, maps couldn't seem to start gps to find my location to start navigating. so i turned on "high accuracy", more to test than anything else, and it found my location and we were navigating home .
i knew where i wanted to go but at some points that varied from where maps wanted me to go. for a while it did good at making quick corrections to my path. about 20 minutes in, i didn't follow its directions again. well this time, it didn't recognize that i didn't turn, then advised me to make a subsequent turn onto a road that was off the road i didn't turn onto. now, the road i am on is about 1/4 mile from the road it thinks im on, the 2 roads are parallel. well it took maps over a mile, after i made another turn towards the road it thought i was on, before it realized it was wrong and made corrective instructions. after that, i made a quick stop to grab some liquid refreshment for the night and turned off navigation, as i was close to home.
this really goes to prove nothing more than "high accuracy" is not always highly accurate. i traveled across 3 states last week for 3 hours on "device only" and never once was it wrong about my exact location.
just wanted to share my experience, really doesn't help or fix your problem, but may shed some light on the possible inaccuracies across multiple devices.

I tried this and yes, Maps works with the "device only" setting. But when using Now it said that location-based cards (weather, traffic, ...) only work with "high accuracy" or "battery saving". So for me this setting is useless.
I guess I'll do another clean install and try CM11 or so...
it's not ROM related
I trid to install CM11 M8 today. For some reason I wasn't able to, received these strange "Unfortunately process ... has stopped" messages all the time and was not able to complete the initial setup. The only hint I found online is to make sure CWM recovery is up to date. I use v6.0.5.0 which I assume is up to date.
So I made another clean install of PA 4.42. Then I downloaded another ROM: did a clean install of SlimKat. This went smoothly, but I have the same location problems, both times!!!!
I guess we can be sure my location problems are not related to the ROM.
One thing I saw that seems noteworthy: I had correct locations for some time and then the wrong locations started again. Maybe this has to do with the system restoring backed up settings or installing / updating all the apps!?
Any ideas?

the only way to rule out the rom's is to return to stock and check it there.
its not uncommon to have similar issues across multiple rom's.
im not saying you are wrong, changing from one rom to another is just not a good way to check an issue.

Oh, is that the case?
Then I should install the stock Samsung ROM and check. Probably will do it in a few days since I am busy the next days.
BTW: I installed SlimKat and then PA again. After installing SlimKat I now have TWRP instead of CWM recovery and the settings of 5x5 Icons on the home screen plus smaller font size and probably a few other settings remain in PA although I did factory reset, format cache and so on...
The thing is: how can I change this back!?!? Didn't find it in the settings. It'not font size (which is set to 100%).

there is another partition thats not normally wiped with a factory reset. i believe its called "data/media". the official cwm's that i have used have an option to wipe this separately, but i havent seen this option in twrp, or know if it wipes it by default. my guess would be no, but i could be wrong.
anyways, some settings and/or app data is stored in this area. you likely need to wipe this to fix the problem. that would be my best guess anyways.

Just rebooted into recovery and was surprised its CWM again!? Anyways, good its back!
The one option I always used is "wipe data/factory reset" (plus of course "wipe cache"). Under "mounts and storage" there's an extra option "format /data". Should I try this one?

I'm pretty sure it says data/media. I don't have cwm on right now or I would check, but I think it is under mounts and storage. It was in the same dir where you can format system and such if I remember correctly.
Its also possible someone removed that option from your version, but I don't know why they would unless your phone doesn't have that partition.
