[Q] Why would turning on wifi help determine an accurate location? - Android Q&A, Help & Troubleshooting

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.

WiFi issue on my Hero...

Hello everybody!
Someone of you has noticed a poor WiFi reception on Hero?
I'm experiencing a poor WiFi reception in my house when Hero is connect to internet thru an access point.
What happen is that after WiFi connection has been established the phone tends to loose it and restart connection thru GSM/3G link.
That happen also if phone stay in the same place without moving around and also when phone is close to access point location.
Any idea about way to solve the problem?
Regards.

Just an upgrade on issue...
If I turn off data connection thru GSM/3G and switch on WiFi seem that WiFi connection is stable so maybe issue come when both data connection are enabled...
Anyway is annoying shout down each time data connection on GSM/3D and power on WiFi!
Regards.
i believe wifi goes idle when not in use. so it connect to 3g or edge. However there is an app if not various in the market already to help keep wifi always on..
Do a search for wifi and see for yourself.

Thanks for suggestion!
At now I've solved turning off GSM/3G data connection when I'm at home anyway I guess that WiFi reception sometimes go away due to issue of the phone or maybe as way to save battery...
when that happen phone stay unconnected so I guess that should be better if I will check for apps that keep WiFi connection always working!
Alex
when the device goes into standby, the wifi is turned off to save battery poweer, and it will go back to 3G.
go into the wifi settings, press menu and select advanced.
select the timeout options
set to never and it will not turn off when in standby.
problem solved and you shouldn't have to turn off Mobile data, although with the settings widget on your homescreen turning mobile data off off each time is hardly going to ruin your life. in fact i tend to do this anyway, just cos i have spent too many years with windows mobile....
Here's an annoying bug I've found tho - on TMob UK
If I send an MMS from home, wifi on, it sits there, and doesn't send the message. Until I turn off wifi and 3G kicks in again.
Now I know for a fact that on my Magic, it was able to turn on 3g/HSPDA to send the message all by itself. Might have a look in thodse advanced settings tho to see if there is something I can do.. Not a biggie, just a bit of an annoyance.

I too, have been doing a search on Forums all over Google looking for a resolution to this.
I have noticed if Wi-Fi is enabled I am unable to send or receive MMS messages.
It is an annoyance having to turn Wi-Fi off each time also I am never to know if someone has tried to send a message in the first place.
Currently using T-Mobile G2 (rooted with MCR Rom 2.8) on T-Mobile UK

[Q] strange wifi problem

I am on bionix 1.3.1 and have noticed that whenever I turn my wifi on it seems to not allow me data access. My web browser will not connect to a page, market won't load, and any downloads that were in progress will fail. it's as if turning on the wifi is overriding my data connection and blocking it. It says that it's connected in the menu though. Any advice?
Thanks
Edit: I just noticed when looking at my phone stats, that when I turn on my wifi my mobile network state says disconnected, and it connects again when wifi is turned off.
Also, I have an airport extreme and a mac, perhaps that is my problem. I've scoured the internet and found a bunch of info about this problem, but haven't found anything that works yet.

Im sure someone will correct me if Im wrong but if you switch from wifi to 3g while downloading the download usually will fail because you were using only wifi to download the content and when that turned off it doesn't just switch to using 3g you have to manually retry the download using 3g .... when wifi and 3g are on wifi doesn't speed up the 3g instead it does the internet related work and the 3g does the text and phone call related work
that makes sense, thanks. as for the connection problem, it is definitely mac related. my wifi seems to work on other networks. I just need to figure out how to make it work with the airport. It's just weird to me that it says it's connected and shows signal bars, but won't access the internet.

so is the new problem that the airport extreme won't give wifi to your phone or that its not working at all
According to my phone I am connected via wifi to my network from the airport, however, the phone cannot access any internet functions when connected. When I disable wifi, it works fine with 3g or edge. It seems to be something with the settings on my airport, not the phone itself.

WiFi disconnect, while dowloading torrents on android

When i downloading torrents using my android phone over the WiFi, its connection lost several times. My phone WiFi policy is "Keep WI-Fi on during sleep" as "Always". I use "Ttorrent" app client. Most of the time Ttorrent display "No suitable network" error. If i turn on the screen, problem not fix.
I have android 4.0.3 ROM and i connected my phone into my ADSL router, not a public.
Are there any solution for me?
Thanks!
Did you rule out the signal strength and wifi network quality? It might just be that the connection is flaky. One way to test is just sitting close to the access point or.. to change it to a different channel (when you suspect interference from neighbor routers is the issue)

Thanks friend your reply!
If I move my phone close to the router, its not fix. Also its possible affect, my neighbors Wi-Fi connections (because of the distance of neighbor houses, to my place). Is it a effect of my router settings?

Is there an option in your client to lower the maximum number of connections? That's a recommendation from the developers of adownloader, which is what I use
I am having the same problem.
I've tried so many things, on the phone and router.
Nothing has solved it.
I've adjusted a lot of settings on the router which have made no difference, I've used different types of security, wep, wpa, wpa2, no security at all. Static ip, changed dhcp lease times etc
On the phone I've tried setting a static ip, flashing different kernels, using different torrent clients, lowering number of global connections to 1 etc
I've also tried a few apps from the play store, wifi fix, wifi static etc
The wifi will just randomly disconnect when I download any torrent, there is no pattern to it but I can't download any torrent without disconnecting.
I would love to know a fix.
I'm using a galaxy s3
One thing I want to try is a different router to rule out whether the problem is the router side or the phone side.
At the minute I have no idea what is causing the issue.
I don't get disconnected when browsing the web etc on my phone.
If I use my pc or laptop to download torrents I don't get disconneted.
Ok I've finally worked out why I was getting drop outs.
For some reason when I use wpa2 with aes ecryption I get disconnected when downloading torrents.
When I use wpa and tkip I get no disconnects at all.
It's not a good solution as I get slower speeds using wpa and tkip but at least I don't get disconnected.
I wonder if this will be fixed?
This is an ICS bug. No matter what you have your wi-fi sleep policy set to, when the screen goes off the performance drops drastically. Download the Wi-Fi High Performance Widget from the market. When tap to enable the widget, your wi-fi will run at 100% performance no matter your screen state.
This isn't a sleep issue though. I have wifi set to always on keep wifi on during sleep.
Even the op said he tried leaving the screen on.
I set screen timeout to 10 minutes so I can monitor the application and also set screen on within adownloader and I get disconnected.
The only fix for me is using wpa and tkip encryption.
As soon as I use wpa2 and aes encryption I get disconnections when downloading.

Well, probably a hardware issue. I have no issues using the same wifi configuration and downloading torrents. And like I said..it really doesn't matter if you have keep wi-fi on during sleep checked. That doesn't matter at all. The performance will degrade so much when the phone is asleep that you might as well have it turned off. No, your wi-fi won't sleep, but it won't be running anywhere near its top performance, which is what the widget is for.
Wow. I have been trying to solve the same problem for last 2 weeks. upgraded windows drivers, router firmware, tweaked utorrent settings and whatnot. finally after reading your answer i changed my wifi authentication from wpa2+aes to wpa+TKIP and WOW. it worked. my wifi is not dropping anymore. I dont why WPA2+AES should cause this problem. BUt this tweak in authentication has finally worked for me.

[Q] wifi issue

My wifi connection often wrong, always in after a period of using, have no access to the Internet. Every time the wifi turned off to open another can get to the Internet, can wifi signal is always full. I searched a lot of method to did not solve, including XDA * # # 0011 turn off on wifi power save mode, when problem solving, but after a while just the same. And with only G mode and so on route, are not solutions. Change a lot of Rom, the kernel baseband all not line.Who's a way to solve?
I am not sure if this is the case but - have you tried different router? My S3 for example has issues when I go to my friend's house (he has some old/er Belkin router). However, when I am home wifi is blazing fast and no issues what so ever (cisco e3000).
my phone has a slight different problem, the phone detects strong signal for all my wifi, but will only save it, and not connect right away, some will not even connect, and sometime the speed is very slow.

I am sure there is no porblem with the router,SGS2 and IP4s with the same router is fine.
I'm getting WIFI problems when waking from deep sleep. My settings are set to keep WIFI on when sleeping only when plugged in, as i find this extends my battery life a little more.
Sometimes it reconnects when waking up, and other times it doesn't and i have to turn WIFI off and then on again to force it to scan and reconnect. If i don't do this and check WIFI, it says it's scanning, but never finds or connects to a network.
Anyone else get this?! I read somewhere about sleep of death on GS2?
There is a known problem with the wifi, I have just changed my phone and so far evrything is working.
been through 9-10 phone with different problems.
Ok, i've tried turning off WIFI power save in the system settings *#0011#
I'll report back with my findings in terms of waking from sleep and possible additional battery drain...
Turning off powersave didn't help on my speeds tho. My SGS2 can pull around 5-600KBs a second, while my SGS3 only pulls roughly half despite being at the roughly same location (ie laying next to each other)

[Q] Wifi always on better for the S6 battery?

Since I always tried to get the most batterylife out of my android phones, I would always set my device up, so that wifi would turn off automatically when in standby.
Now a friend of mine, who also got the S6, told me, that with the S6 I should set the wifi, so that it never turns off, not even when the phone gets to standby. His argument is, that when I'm constantly at home or at work (with wifi connections available) the wifi would use less battery power, than the 3G or 4G connection.
Also he sent me this:
http double point //www dot androidcentral dot com/android-101-save-battery-keeping-wifi-alive
(cant post the link ._.)
Is there any truth to this? Should I really put the wifi sleep policy on "never"?
Any opinions?
This is a two-fold question that requires two answers. You are both half right. Wi-Fi should be disabled when there's no hotspot nearby. Otherwise, your device is wasting battery seeking for a connection. On the other hand, if you're already connected to a recognizable Wi-Fi hotspot, Wi-Fi should be on even while the device is locked. It would have a battery-adverse effect if your device has to re-enable Wi-Fi each time it sends out beacons for email, facebook, twitter polling. Nothing preserves more battery than enable Wi-Fi and mobile data only when those sources are available. You can use one of those automatic Wi-Fi/LTE enablers found in the Play Store.
On point!!

WI-FI takes less power than 3G, 4G connection. That for sure, i've tried it several times.
