[Q] WiFi Tethering Drops - Galaxy S III Q&A, Help & Troubleshooting

XDA, you really are my last hope.
I use my phone as my primary internet device. Tethering works fine for 15 mins and then one of two things happens:
1) Computer doesn't load webpages (stuck on looking up....). Have to turn my computer's wifi off and on again.
2) Tethering is still 'on' but the hotspot vanishes (have tested this on more than one computer) have to turn wifi off and on again.
Problem number two is by far the most frustrating but both are seriously annoying as I cannot play online games or download files and my girlfriend work is constantly interrupted.
I have tried:
1) using FoxFi - Works but same issues as native tethering software.
2) Rooting and using barnacle, wifi tether, OpenGarden WiFi (get 'could not set ad-hoc mode of wlan0: op. not supported on transport endpoint.)
3) Turning off fast dormancy (no difference).
4) Setting Wi-Fi to always on.
5) Turning off Wifi Power save mode.
6) Searching google, asking reddit, searching XDA, crying.
If you can fix this once and for all, I'll send you $10 over paypal (if that's not against the XDA T&Cs). I'm a poor student, but I am THAT desperate.
Many thanks.
New Samsung Galaxy S3 (International GT-19300).
UK 3 Network - The One Plan.
HSPA+ Area.
Stock firmware, Android 4.04
Build: IMM76D.19300XXBLH3
Rooted (problem both before and after root)

Tell me if you need more information.

And I will press that thanks button, you have my word!

Last one.

I don't have a solution for you, but I can share my experiences regarding the same problem you are having. I also tether a lot and for that, this phone has been awful thus far. I have pretty much given up on wifi tethering for now and am tethering using bluetooth since that seems to be working MUCH better for me. So do give bluetooth tethering a try too if it's possible for you.
I get random drop outs in my mobile data connection - this happens all the time, also when I'm not tethering. I have been trying out different modems to help with this, and now I have found a modem that works pretty well for me. I'm using XXDLIB firmware (Jelly Bean) and have found that the modem that works best for me is XXDLI4.
Maybe through additional testing of different modems I would be able to find one that works even better, but I've been doing this for a long time now and getting pretty tired of it!
Wifi tethering for me on DLI4 modem is now OK - not great, not even good - just OK. It feels much slower than bluetooth tethering and is still unreliable so I go with bluetooth for now.
Sorry if this wasn't helpful at all... :angel:

[Q] Internet connection problem (WIFI)

Hi all,
I got problem with internet connection on my HD2 (ROM 1.48). There are 2 ways I connect to the internet - WIFI and GPRS. GPRS connection works fine - I can download and read e-mails, make backups with MyPhone, update weather information, etc. But when I connect to the internet with WIFI, there are only 2 things I can do. I can browse web pages with Opera and update Twitter messages. But I can´t download e-mails, make backups, update weather information, etc. When I try to update or backup something, there is connection error (through that connection between phone and router is fine and web pages are running).
It seems to me like most of applications want to connect to internet via GPRS only. Is there any way to set up (or check) the phone to connect to the internet via WIFI when it is turned on?
Thanks for any advice
Sorry cant help but agree - it would be fantastic if there was some way of knowing / controlling when it used GPRS data and when it uses wifi. When wifi availabe obviously would rather use that than be charge a small firtune for data.
Any one out there about to help with this??
Internet browsing
Ditto. I can - after HUGE effort - connect WiFi but I cannot browse the internet using either Opera or IE. 2 year old Nokia connected and browsed literally within 2 secs! Also, the phone keeps connecting via GPRS all the time even with data connections off. Can anyone help? Thanks PS I know it's unproductive & forgive me, but I have to get this off my chest: this is the worst cellphone I've ever owned. Bluetooth doesn't work, internet doesn't work, handsfree car kit doesn't work. Does anything work?

correction, YOUR Bluetooth doesn't work, YOUR internet doesn't work, YOUR handsfree car kit doesn't work.
Get it exchanged. (if they genuinely dont work)
@others, go to settings menu all settings connection connections advanced select networks.
there are two dropdowns, in teh top one should be the name of your mobile data, , this is what automatic progs will use to connect to the web, in teh bottom one it should be 'the internet' (or sometimes 'my work network'), meaning they use wifi if available, and data if not.
(At least thats how they should work....)
If you set the top one the same as teh bottom one, nothing should try to use mobile unless wifi is not connected.
Could be a proxy problem? some operators set up a proxy, which can screw with connections.
samsamuel: Thank you for your advice. I´ve tried it - in both dropdowns I got "my work network", but no success.
I´ve found something interessting. When I turn on YouTube client (using WIFI), I can´t play videos. That should be ok when I got problem with internet connection. But YouTube client shows on the welcome screen preview of today´s added videos. So the question is why should application download preview of video, but it can´t play the video? I´m a little bit confused
Thanks for the suggestion, but I had tried that already and it did not work. I don't think it is just my cellphone. There are many comments re the HD2 that make it clear that it does not work with a Parrot handsfree carkit, Motorola S9 headset etc, and the 2 earlier posts reveal problems using WiFi too. It seems to be problematic on many fronts. I cannot even connect it using Windows Mobile via an USB port! And while I appreciate all suggestions it seems to me that this model is a (very expensive) lemon and frustrates huge numbers of owners. I find it odd that a 2 year old Nokia N95 can connect and browse instantly and a 'smart phone' doesn't work at all. I find it to be very gimmicky. I don't need twitter, facebook etc. I need voice dial, good PC software (like Ovi and PC suite) and bluetooth that works etc. The HD2 has none of this, but great graphics of a windscreen wiper, exactly the sort of pointless gimmick that reveals that the designers were interested in making a toy and not a useful phone.
I suggest you try and install "HTC_Wi-Fi_onDemand_by_Krocher". This program will always use wifi when available and stop the GPRS from connecting and will also keep your wifi on a stand-by. Please do read through the thread as you have to make sure that no programs using wifi are activated when you want it to be off. For me it solved several problems with wifi.
Second thought is to upgrade to one of the much more stable and already tweaked OS's. There are quite a lot out and you'll find everything about that on this forum as well.
Last thought, if it does not work it must be something to do with either the settings or the OS version as for others it works absolutely fine. These are complicated phones that, much like computers, must be set and tweaked to the correct settings in order to get the best out of them. If you just want a "buy and run" phone this is not the one.
Success,
Itamar

[HELP] Ray WIFI and GPS problems

So I've got my Ray for a few months now, but ever since I have problems with the WIFI and GPS connections.
GPS:
I used to use Navigon on my Acer Liquid, but that app doesn't work anymore unless there's an active data connection and I don't have a data plan. Now I use CoPilot Live Premium 8.xxxx. App itself works well, but the GPS signal get's lost every few minutes and I have the feeling this is getting worse. Especially in cities it's posible I have to wait for like 15 minutes to have a signal and after that the signal gets lost every 2 minutes or so. Is this just due to a poor GPS receiver in the Ray or what?
WIFI:
I can connect to my router (WPA2-Personal AES) but only for 2 minutes. After that, the icon in the status bar shows that my Ray is still connected to the router, but there is no internet connection anymore, eg in the market pages keep on loading most of the times without saying the connection is lost or so and I have to turn off WIFI and turn it on again after a minute to have it working again for 2 minutes -_- If I do this a lot, it even kicks my computers of my network and I have to reboot my router
I hear there a quite a few problems with the WIFI in kernel related situations and it's often solved by using a custom ROM, but I would like to stay on stock ROM.
What could be causing this? The router, the WIFI security...? I didn't have the chance to test it on another router, maybe tomorrow.
Any help would be appreciated!
For the wifi, if you could test it on another network, we could know if the problem comes from your phone.
For the GPS, if your phone is rooted, I suggest you this application, with every Android phone I have I use it, and I have a some-seconds signal acquisition. It may fix your problem, but I don't understand its origin.

Thanks for the app tip, I will try it!
Try sygic for navigation. It's free and for now it worked with no problems for me.
I have some problems with wifi too. At home i can connect to the router freely, when using my laptop as router it shuts the laptop down, at friends it restarts his router it almost looks like Ray is to aggressive when connecting.
I looked into the problem again today and finally, I got it working.
The things I did:
1) Router firmware update (Dlink DIR-615)
2) Removed Ray's DHCP settings from the router and added them back manually so it never expires.
(Up till this point I still had the same issues.)
3) Changed the WIFI mode from N and G mixed to N only
=> PROBLEM FIXED
There seem to be a lot Xperia users (especially Arc) with my kind of WIFI problems. This thread was very helpful:

I don't have GPS problem as it connects within 1 min without AGPS support...
But i do face wifi problem especially when downloading larger files >100mb.. It constantly gets disconnected...
The wifi disconnection is genuinely present when i am downloading torrent files... It just kills the connection then connects again... I literally can't download any torrent files especially larger ones like movies etc...didn't have this issue when i had HTC sensation...

[Q] Internet stopped working on wifi on .73 SG build

This is most bizzare. My internet on wifi was working fine until last night, but it is not working any longer. Works fine on 3G though. On wifi I am able to see connected devices on the local network and play files off my HTPC but internet browsing, google play store or anything that uses internet has stopped working and times out. All other wifi devices in my home are fine. I have reset the wifi router as well, nothing. Tried to disable and enable wifi on the phone and restarted a few times as well. Cant really put my finger on it.
Any ideas?
I updated to the SG .73 build about 3 days ago. I noticed batter battery life, no where near what I was used to on my GS2 though.
Anyhooo, any ideas guys, I am concerned.

That's unlikely to be your device. Probably the router or something.

I have also messed around with the wifi sleep policy. No issues there. Power saving is also disabled.
Could it be anything else? An app maybe? I will remove the most recent ones and report back. Badass battery monitor was the last one I installed.

Hi, along with that also try to connect to some other router and let us know if the problem persist.
The wifi connection remains active but no internet. Just thought I would add. I will connect to another wifi hotspot. My wife's GS2 tethering and report back.
I assume that you got "limited connectivity" problem.
If my assumption is true then you should try checking in your Wifi router setting, set encryption method to AES. The problem was addressed when I tried doing this and in addition, changed my Wifi channel from auto to a specific channel.
Right, not sure how this all started but like many others my internet connection (More specifically over wifi) just randomly stopped. After a fair bit of reading on both these forums and Sony's own forum, I downloaded and installed an app called WeFi Pro. Somehow this seemed to fix everything and now have a working wifi internet connection again.
Will do some more reading into this but as a fix i'd recommend installing this app. Oh BTW its free so its a win all round!!

[Q] WiFi Tethering issue

Hi I recently restored my s3 to factory reset but after that I am not able to connect any devices (phones or laptop )with wifi tethering
Prior to reset it was working fine. I have not rooted my phone.
Do I have to reset it again? Any other possible solutions?
Can you explain it in more detail? If using hotspot, are your phone close enough with the device you want to paired? Did you try bluetooth or usb tethering? Did your phone have data connection?
Having major issues with tethering on my SGS3 aswell.
When I recieved the phone, stock out of the box, I was unable to get tethering working, it worked for 10-60mins then automatically turned off.
I rooted the phone, and tried various tethering apps, and finally (after a couple of days) managed getting FoxFi to give me a stable tether.
Now I've installed the latest FW, and Im back to square 1 (or even further back), FoxFi puts up an access point, but after being connected 10-60mins, tethering stops working, and the connection dissapears from the list on my computer. FoxFi still reports it's running, so I have to turn it off, then back on to get another 10-60 minutes.
Keep Wi-Fi on during sleep: Always
Build Number: IMM76D.I9300XXBLH3
Android Version: 4.0.4
Considering trying Cyanogenmod, but I really like the stock room and wish to stay on it.
USB tethering is out of the question, as I use it for Xbox360, PS3, talet etc.
For those wondering, usually having 10/8 mbps @ 80ping, limited to 20GB traffic a month, aint that bad tbh.
Might just gotta get me a proper and wired internet connection instead.
Anyone got any idea what so ever what might cause this? Ill be more than willing to post logs etc, just tell me how.
One more thing, some of the tethering apps gives Ad Hoc error, FoxFi the only I've not getting this error on (of those Ive tried atleast).

[Q] WIFI tether completely broken

I have a droidX with liquid ICS 1.62,
android version 4.0.4,
and kernel version 2.6.32.9-g34b306d
i have tried every possible method i have found to get wifi tethering working, its to give my nexus 7 wifi on the train
I'm able to tether with bluetooth, but because there's no wifi connection various apps dont "see" the internet and ignore it.
so i need wifi tethering
BUT IT WONT FREAKIN WORK. :crying::crying:
more specifically, no matter what i try, nothing can see the wifi tethering signal of my phone, its as if nothing is there at all.
it'd tried; Foxfi, PDAnet, wifi tether for root users, barnacle tether...
i'm completely at witts end here, ask me any question you need and i'll answer in as much detail as needed
anyone? at all?
if you need any more information, i can provide it
guess not
i'll probably have to drop back down to CM7, it looks like every single ics or jb rom for the droidx has this dumb issue. thanks verizon
wait, nevermind, got it working again somehow
after flashing back to stock liquidICS 1.62 i found it working again
i tried to underclock the phone so i could leave it in my pocket running wifi all day, but apparently under OR overclocking the phone AT ALL breaks tethering, dont ask me how or why.
if you change the clock speed at all, you need to reboot before using tether
