[Q] WiFi Location Incorrect

It used to be, when I connected to my WiFi, it new exactly where I was. Now, I think since I have my Desire HD, it thinks my WiFi network is about a mile away.
Even worse, my Dad moved about 200 miles, when he connects to his WiFi it shows him in his old house....
How can these be fixed/corrected?
Thanks.

Hi,
I'm pretty sure that when Google drive about collecting StreetView images they log every wireless network they stumble across, this is then tied to a GPS position.
If you remember in the news recently Google were subject to an investigation because they collected data that was transferring between these wireless networks whilst collecting StreetView images.
Your fathers wireless router would have had it's location plotted previously, but now its incorrect due to him moving.
As for your router, it may have not had it's location plotted so the position you are given is the telephone/broadband exchange that you are using.
Google the website SamKnows and use that to find the location of your exchange, see it these two locations marry up.
Hope this helps

[Q] (SOLVED) Weather widget showing wrong location

OK, first I know that there are many threads about this problem, but mine is a bit different. I searced on google for a solution, but got nothing so far.
Since a few days the official HTC weather widget started showing an incorrect location. By incorrect I mean that I live in Hungary and it shows Naples (Italy).
The wifi location is turned on in settings.
When I switch on GPS and it locks on the satellites, I see that the widget updates to my Correct location (Hungary). When I switch it off, so only wifi again then it goes back to Naples.
Not only the location, but the weather forecast is incorrect too.
The weird thing is that not only the widget but Google Maps, Locus and every nav app that can use wifi to locate me (with GPS switched off), show me that I'm in Italy. I tried Weather Bug, Fancy Widget and they all say Naples, but why??? I've never even been there.
It's definitely not ROM related, I tried several, even went back to stock, but it didn't help.
One thing I figured out, that I connect to the internet wirelessly (obviously) through a D-Link router. Today I just had a feeling, what if the router is causing all this. I switched it to my old SMC router and then I updated the weather widget through that. And voila, everything was back to normal. It showed correct location after several weather updates.
After that I went back to D-Link and then I found myself in Italy again
So my question is, is there any setting in the router that can be modified?? I did firmware upgrade too, but it didn't help either. The time zone and other stuffs are set correctly in the router.
I don't want to go back to the SMC router as it was freezing a lot and that's why I switched to D-Link.
Things that I also tried:
Remove and readd widget then setting current location
Deleted the other cities that were in it
Well I can set the widget to a specific location, but I would like to have it updated automatically by my location.
Any help is much appreciated.
SOLUTION:
Everything is OK now, the widget shows my correct location, Google Maps is showing the correct city. I don't know what was the real solution. It could be coincidence or some stuff that I did.
Here are the things I tried:
-I submitted my D-link router's mac address at skyhook, so that it knows my correct location. Google uses MAC addresses (not IP address) to find us when using wifi and not GPS.
Here's the link where I submitted the MAC: http://www.skyhookwireless.com/howitworks/submit_ap.php
I selected my location on the map then entered the router's WLAN MAC ADDRESS and submitted.
-I also cloned my previous router's MAC address, because as I said the positioning worked well with the SMC router.
Changed my router's ip address from 192.168.1.1 to 192.168.2.1 (don't know if that helped, I just wanted to copy as much option as I could from the prev. router)
-(This may have nothing to do with the problem)I visited the mobile version of Accuweather.com on my laptop and selected "Current Position". It found my location correctly. And after this I saw the correct place on my phone too.
These are the things I made to solve it. But don't take is for sure. It could be only coincidence and maybe some of my modifications were unnecessary, but I'm now happy that it works again

Are you sure you are not using a proxy on your dlink router?

I'm not sure, it runs on stock settings. I don't really know how to set up a proxy. I only added WPA security to wireless.
I just checked my bro's Spica, he has Fancy widget and it updated well through D-Link. Now I totally don't get it :S
I'll try to reassign a new IP for my phone.
I also made the DHCP release/renew stuff.

Solved it. Updated OP

I know this an old thread but I was having the same issue with my new HTC One and evo 3d for past couple weeks. I live in KS and current location was stuck in Kentucky when I was on wifi at home. I submitted thru skyhook, shut off all wireless devices and renamed my ssid then rebooted router and airave and so far so good

[Q] AT&T Galaxy S III, WiFi 'authentication' issues and router question...

*EDIT* Posted in the wrong section; my apologies. i was looking in Q&A and hit 'new thread' in General. Move please? Again, sorry!
My GS3 will not connect to any WiFi networks. I have 13 days remaining to return/replace it. I have tried on 3 different routers; a Linksys WRT-54G, Belkin F5D8233-4 Wireless N router, and whatever D-Link router a local coffee shop had.
I have tried the special command *#0011# (or whatever it is). i have tried disabling WPS, changed router channels, disabled all security, switched between 20/40Mhz and 20Mhz modes, and reset/forgot every network and router probably 20 times last night, to no avail. From 2 feet away.
From what i have read, it appears to be a software glitch; pre-Sept 22 update didnt have the same problem, and the fact it keeps flashing 'incorrect password' and then gives me an authentication error, on fully unprotected networks, leads me to believe it is in fact software related.
Has anyone successfully connected to a router (if so, which one? specifically please), i am going to buy a second router to cover the rest of my house anyways (its big, cinderblock, steel, brick, and mortar with solid doors so WiFi doesn't penetrate very far), and i dont mind waiting for a fix (if its coming) for WiFi.
Its not a big problem because i have a grandfathered unlimited data plan, and i don't use data or surf much (average of 1.5 gigs a month for myself; 4-5 gigs when my girlfriend is home) so i dont actually need WiFi, but i paid for it, and i expected it to work.
As far as the routers I have, my sisters' my now-retired Motorola Atrix 4G, iPhone 4, my girlfriends' Blackberry Bold, my mothers' Kindle Fire, my fathers' iPad 3, and their iPhone 3Gs, three computers, one server, two laptops, and two printers all connect flawlessly. Even my *ancient* HTC Hermes and HTC Kaiser connect just fine, as well as any of our friends or guests devices. My friends' Samsung Galaxy Note also connects just fine (though i do not know which Android version she is using, or if they share the same WiFi chip).
So, in conclusion, how many others have this problem? did you have the same problem before the latest OTA update? and for those of you with no issues, which router models are you connecting to?
I just want this feature to work; we travel a lot, and rely on WiFi to communicate and do business abroad, so i will need it working in the coming weeks, and i would MUCH rather use take the GS3 over my unlocked Atrix.
Thanks in advance!

Sounds like a bad phone. Exchange it.
Sent from my SGH-I747 using xda premium

I seem to have stumbled upon a solution, mostly by accident. Even though i had repeatedly reset every variable and security feature, disabled everything and tried probably 20 times, with old and new firmware, i could not get it to connect and was about to return the phone.
Then my father came over with his new iPad; and it wouldnt connect either. I did a factory reset on the router, disabled everything (WPS, WEP/Security, firewall, etc) and both connected, seamlessly, and stayed connected.
Since then, it has connected just fine to any WiFi network; i never changed any advanced features on the phone, and i do not have to utilize the #*1100# trick; the signal is as strong as that of any other wireless devices. I believe there is a glitch or bug somewhere in the software on the SGIII, however, as it had been giving me authentication errors or 'wrong password' errors on completely unsecured networks. After i reset and factory restored the router, all is well. I havent set up security on my network at all, but i have both the iPad 3 and Galaxy S III here to play with, and i will go through different options until i identify what security feature, specifically, each does not work with.
I will attempt to post any errors and log dumps here so perhaps the community can fix it instead of waiting for Google, but i am unsure how to log and post them from the Galaxy S III, any pointers would be great.

Returned home from short trip, Wifi connects but does not function

As the title says, I didn't change anything about the phone's configuration when I was out, didn't download any new apps or change any settings that would interfere like this. No one else has changed my home network in my absence.
Nevertheless, most of my apps, such as Instagram, the Play Store, Twitter, Wikipedia, Chrome; almost all their requests time out. There seem to be short windows where data will load, and Instagram appears to load comments and post metadata, but no images. It's basically unusable. Occasionally an exclamation mark will pop up over my Wifi symbol in the notification center. Strangely, I can still reach my Steam and Battle.net authenticators, but the moment I try loading the Steam app, nothing comes up. It's like the device can only handle plaintext over Wifi.
All of the apps work fine over cellular data.
Also, there is a toast that appears whenever I restart my phone that says "Power On" that I've never noticed before. I was rooted using Xposed, the only modules I used were Snapprefs, Xinsta, Physical Button Music Control, and Greenify Experimental Features, all of which I uninstalled. The toast still appears with the latter two disabled. Only other rooted apps I had besides Xposed were Nova Launcher, Greenify, Busybox, and Root Checker Basic, all of which have been removed but Nova.
I am running 6.0.1 with the latest update.
Any ideas? I am still within 15 day warranty so I could theoretically return the phone (which I was contemplating doing anyhow since 10gb of functional storage is a bit too small for me), but would rather not have my hand forced, and eat into my cell data plan.
So far I have tried forgetting the network, wiping cache/dalvik with TWRP, removing the Google VPN, resetting all network settings, and a couple things I can't remember offhand now. Any suggestions will be appreciated.

First, if you want to return your device because the 16gb model doesn't have enough space, go ahead.
If it is mostly because of this WiFi issue, I wouldn't return the device, it is almost certainly the case this is some configuration issue (possibly in concert with some Android bug) which can be resolved.
Is it possible when you came home the device connected to a neighbor's AP and thus you couldn't use data, but it wasn't immediately obvious, so you ended up forgetting your own network and reentering the config, but the key was off by a little, and from that point on, it was just assumed the wifi config was correct?
When you say Google VPN, are you using WiFi Assistant and Project Fi? Have you tried disabling auto-connect fir the WiFi Assistant?
Have you tried using the old Lollipop DHCP client (perhaps your IP address got used by another device and the new Android client doesn't handle that well?) Just grasping at straws.
Have you tried turning on Bluetooth while WiFi is on? Perhaps there is a bug with them working independently of each other in certain situations.

I am 100% positive I am on my own home network and that I used the correct key. I'm not sure what you mean with regards to the rest of the 'config', I have always used the standard wifi configuration, just typed in my key and had it work.

I actually forget what it was called, it was under Settings>Wireless&Networks>More>VPN. There was one entry there with an icon. I forget the name of it, but the icon looked like a stock Google icon and I think it had google in the name. I am on Project Fi, not using any wifi assistant (at least not in Advanced Wi-Fi Settings), but when I tried to toggle that option on just now, something called "VpnDialogs" crashed, so I assume that VPN entry was that. But again, the assistant wasn't on.

I did, when I first googled this was one of the things I found, sadly it did not help.

I don't use Bluetooth, and trying to toggle it off/on from the control center just gives me a repeated "unfortunately, Bluetooth Share has stopped" error message.
I have decided to get the 32GB 5X since I do want more storage, but since I would like to be able to root my phone again and use Xposed, I would still like to hear any other ideas you have for troubleshooting this problem in case it reoccurs.
I reflashed the latest update to see if that would fix it, no dice. When I send the 16GB model back I have to factory reset it anyway, so I suppose I'll know if that does it.
What puzzles me is why I can load text from instagram posts that have been posted while I've been having this problem, but not images. Makes me think that maybe my connection is being super throttled somehow rather than non-functional, but my PC's speeds are normal. Perhaps some internal part is damaged? I do have a case and it hasn't taken any serious tumbles, but it has had one or two small falls from maybe 2 feet high.

It is easy to test if you have some network connection vs none.
In terminal or adb shell
ifconfig wlan0
ping www.google.com
1st command will tell you (among other things) if your wlan picked up an IP address.
2nd command will test whether you can send ping packets over your connection.
I'm sure there are millions of ways of doing the above, I just gave you one example.

Strangely, the solution seems to have come from factory resetting my router. I ruled this out initially because my other old phones were working fine on wifi, my phone is now getting WiFi again.
Now to figure out what the hell this "Power On" toast is about...

I've encountered something similar where the router runs out of NVRAM space because it has recorded too many DHCP clients, it won't hand out new IP addresses, but if you are existing or already have one, it is fine.

Question SM-F926B sporadic "freezing" data connection [with O2 Germany]

Hello together,
since I couldn't find anything about that issue in detail beyond the usual vague articles (where one copies the mediocre content from someone else, it seems) such as this one, I'd like to share the following:
Using a SM-F926B which natively came with Android 12 (F926BXXU1BVA9 preinstalled and also after having it updated further to F926BXXS1BVB3), I have the issue that the data connection using 4G(+) (APN-wise and nowadays the lovely internet access of course) although staying connected, doesn't pass any traffic anymore at some point. The small "arrow" in the upload direction is periodically showing up then but nothing in the downstream direction, rendering the whole thing effectively offline, both directly and any tethered device connected to it, which is very annoying. Only quick resolution is to toggle the famous airplane mode.
While it is on one hand appreciated to occur not all the time, it also makes it more difficult to narrow down the error. In conjunction with the German provider O2 it occurred maybe every 1-2 days. During the last time it happened, I had a SMS being sent to the Fold which got successfully delivered so the mobile connection itself stays active (neither does the service monitor available though *#0011# shows anything suspicious) so it seems to be an issue with rather the APN-related connection. A problem with the provider network can be ruled out though as a Netgear LBR20 with another SIM from the same contract runs perfectly fine since ~ 180 days.
Meanwhile I downgraded to Android 11 (F926BXXU1AUJ7) to see if the same error occurs as well, hinting on a hardware issue (a very interesting one then, though as the overall data throughput performance of the Fold 3 is amazing) or some incompatibility with Android 12 (which would then however also raise the question why not all exemplars are affected the same way, which suggests hardware differences even within one model line such as that very F926B).
Has anyone of you experienced that or a similar phenomenon?
