Sprint SGS3 Wifi Tether closes itself...help!

Hey guys,
I am enjoying my Sprint variant Galaxy S3 a lot, but after rooting and installing the wifi tether/hotspot app, it works great, but I am having some issues and was wondering if anyone else had the same issue or if someone knew how to resolve this issue.
The issue:
While everything works just fine for a while (I am posting this thread using wifi tether) often times I see the wifi connection has dropped on my laptop and when I check my phone the wifi tether app is no longer running. I have to restart the app and everything is fine. This is getting pretty annoying as it happens very randomly! I haven't had this issue on my Epic 4g Touch at all and was just curious if maybe there was something I was missing or if perhaps others were experiencing this as well. I drop time varies a lot...sometimes I can use the connection undisturbed for 1+ hours, but other times the app closes after 10 minutes and requires a restart...its just more of an annoyance than anything as the program does work every time its restarted, but It would be nice if I could get a solid/stable connection going despite the lackluster 3g speeds.
If anyone knows a fix or could help me out, this would be much appreciated! I did a search and couldn't find any open posts about this :[
Thanks!

Edit:
Hmm... Ok It disconnects about every 15 minutes or so... I tried changing the profiles to multiple different ones (Nexus CDMA, Galaxy S2, Generic ICS) All with the same result...it disconnects and I have to click the white wifi button to restart the tethering. :/ Happened on stock rooted and I just did a full wipe and installed the Blazer ROM and seems to be the same. Thanks again if anyone has any kind of input.

Hey man...it seems like it holds on to the signal longer and when I uncheck it, it dims the screen but it doesn't fully shut off...it seems to like that and keep the connection. When I manually turn the screen off it will disconnect me again. I hope its not my phone! Its definitely better than before!

Well unfortunately, I always have my phone plugged in when running the app so the screen being on isn't a problem for me.. there are some apps out there ( i can't seem to remember the names right now ) that will try to prevent the app from being killed by android's task manager, i'd look into them... good luck

Wi-Fi only when home network is available

Is there a way to setup the phone so it will only use your home wifi when it is available? I don't want to manually have to change this all the time. I want it to use my home network when it can connect to it. If it can't then use 4g. Anyone?

In cyanogen there are profiles you can set.
But if you're stock there are third party apps that you can use. I believe they even track your location to know if you're home or not.
Or just leave WiFi on all the time and it will connect when in range. But might kill your battery quicker since it will be scanning constantly

Thanks for your response. How do you give someone a thank you or whatever its called? Someone flipped me **** because I hadnt given any. I dont know how.

I use LLama ---> https://play.google.com/store/apps/...t#?t=W251bGwsMSwxLDEsImNvbS5rZWJhYi5MbGFtYSJd
My wife uses [email protected] ---> https://play.google.com/store/apps/...wsMSwyLDEsImNvbS5hZWJlaW5yb3RoLndpZmlob21lIl0.
They both work. LLama does so much more than what you desire and [email protected] only does what you want.

Click the thanks button on the left side under the name and post count. If you're on the xda app just click the post.
I'm pretty sure the phone will only connect to a network when you tell it to so you can just leave wifi on. From my experience wifi didn't really use that much more power. It'll just connect automatically within range.

Additionally, there's ways to change the scan interval times so it doesn't check constantly.

If you wanna impress some folks buy some Nfc tags and set them up.

[AIRDROID] Not respoding when the phone is locked

Hello,
I just installed Airdroid and works perectly when phone isnt locked but at the time you lock the screen, it stops to have any communication with the Airdroid webapp. I have not realized this behaviour on my preivous owned Galaxy S. Does this happen to anyone?
Thanks!

If you are using the pattern lock - then this is normal.

Thank you brainmaster. There is any possibility of bypass this behaviour and keep the pattern lock?

Setup a task (Use tasker/llama) when you're connected to home wifi to remove your lockscreen.

Wow, I always want to do that besides of airdroid. Actually, I have been messing around with llama but cant remove the lockscreen, I will check tasker anyway. Thank you!

Hmm from further testing, even if I don't have a security, as long as the screen is off AirDroid has problems...

I got the same problem here... only with nexus 4. It works perfectly with others phones...

Switch to another kernel maybe?
Sorry for my bad English.

I'm glad I'm not the only one with his problem. Has there been any updates?
I'm running Nexus 4 running 4.2.2.

Are You on WiFi? Is Optimize on in advanced WiFi Settings?

You could be running into the Nexus4 wifi bug. Try the recommended fix in that thread and see if it helps. I've been having problems with VOIP over wifi while the phone's sleeping and the patch helped but didn't fix the problem completely. Maybe it'll work for you.

This. Remember the patch works best with 4.2.1, 4.2.2 still has issues with the provided fix.

Ahh, thanks all. It seems like it's not me but it's Google's bug they haven't fixed yet. I hope they get this fixed soon.
Thanks!

[Q] Fails to automatically connect to mobile data after Wifi

Does this happen to anyone else? Quite often if I've been using the N2 in my home, when I go out and about my phone will not be connected to mobile data (3G) and I have to toggle airplane mode for it to kick in?

Not had this myself, sounds like the cellular connection is going to sleep and not waking when your note 2 polls for a connection. Are you on a stock rom or a custom, can you post your android version number as well, will help anyone else who posts who may have more information for you.
If your rooted you could try pulling a log at the time you switch connections see if that yields any useful data.

Same here on a german device. I use manually select the Provider. Then it connect. Thank you for the tip with the airplane mode. But I search a way to kick this big. In a german forum a member says that a Fullwipe helps.

Its a stock rooted ROM version JRO03C.N7100XXALJ1
Can anyone tell me what to look for in order to create a log? (I don't expect a tutorial just someone point me in the right direction).
The problem is intermittent.

Give this a go, should allow you to create a log during the time you have the problem then you can see what android is or is not doing at the time.

Not something I have had myself but my gf has this same problem with her gs3. After having a look around our seems to be fairly common on the gs3 so any help with a fix would be great. I can only assume that it's something that will be fixed with a fw update from Samsung.

I have the same issue and so does my girlfriend on her SIII.. Can be really annoying as I might leave somewhere with wifi connectivity expecting the phone to automatically connect to 3g and I miss things like whatsapp messages with no warning :/
When I realise I do use the flight mode trick to fix it but it's annoying that it happens.

tmobile hotspot

hello everyone, I have a rooted s4 on t mobile, i am using cyanogenmod 12.1 , my question is. up to now I was able to use my hot spot to watch Netflix on my Roku stick
without being slow down, today i noticed my Netflix would not work, I call t mobile and they told me it was because I had use all my allowed data, I never had the problem before, how can they tell I was using the phone as a hot spot, I though if you were rooted they could not tell if you were tethering, any answer will be greatly appreciated, thanks in advance

Dump that CM garbage and flash a TW or GPE rom.

So do you think it's Cm vi that caused it, I had a gpe rom before

It's just a good guess, but yeah. I've only ever had problems with CM or any rom based on CM.

CKC - I just started having issues this week too with my Hotspot. I'm on the latest insane hybrid TW

Probably was using a apn for tethering that wasn't the normal lte apn

Thus has nothing to do with what ROM you're running; since so many people are abusing the service (ie. forgoing home internet and using their phones to tether to), carriers found a different means to see who is tethering, and are cracking down in them.

Potential workaround for throttled hotspot?

After tinkering around, I found a workaround that is working for me so far so I decided to post. I am on insane hybrid and obviously rooted.
Installed newest google tether app (experimental version): https://android-wifi-tether.googlecode.com/files/wifi_tether_v3_4-experimental1.apk
- Left it as unsecured but enabled the access control
- Changed setup method to WEXT (ad-hoc) and started tether.
Streaming, downloading, Dropbox are all now syncing on my computer and I have full speeds again after being throttled. To browse with chrome, I installed the extension "user-agent switcher" and changed to "Samsung Galaxy S3".
I am curiuos if this works for anyone else, or if anyone has found an easier fix. Thanks.
