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

Wifi connectivity issues

Hey all, I was hoping someone else has had this issue and has fixed it. I'm running a stock unrooted phone and when I connect to wifi, it connects to the AP and obtains an IP, but I cannot go out to any website or use any app that needs a connection (facebook app, etc). Things I've done:
Restarted phone
Factory reset phone
rebooted router
Tried other roms
Sent to samsung (they did a SW update) x2
Forgot the network, then reconnected
This is getting extremely frustrating as it's been this way since I've had it, but it got worse with the ICS update. Anything that anyone has tried and actually worked? The funny thing is, when you reflash the phone or do a factory reset, it works for about an hour then stops. Thanks in advance!

Have you ever connected that phone to a different wifi?
I encountered an issue a few months back where something went wonky and i had to completely reset my router and set it back up. Have you tried that too?
sent from my T989 full of CM awesomeness and a touch of Venom from the Darkside!!

Yes, I've tried different wifi AP's and none of them have worked, while others are on them including mine at home. I have not reset the router and reconfigured it because it's a cisco and as such is a pita. I have looked through my config and cannot find anything obvious. But still, others are able to connect just fine.

Same issue here. Never noticed it until recently. Reflashed LE1 and it worked for a couple of days. Going to flash the galaxy note modem tomorrow.

I know it's a shot in the dark, but some said it worked....
Try to disable the "UPnP" in your router.
Let us know....

premiatul: I can't find anything in my router for upnp. If anyone knows how to disable it in cisco ios 12.4(11)T1, I'll gladly try it.
Autx: please let me know how that goes and if it works. Thanks!

Is darkside wipe a temp or permanent fix, from what you've read?

Noone else has any info that may help? I would really like to get to the bottom of this. Devs: could this be a driver/kernel issue over a hw issue?

Honestly, whenever I'm running a TW based ROM I find that wifi takes awhile to connect. Any AOSP (CM/AOKP) for me is nearly instant.

I'm running a stock, unrooted device. It connects to the ap and gets an IP address just fine, but data doesn't go across the connection when I go to the internet.

Thanks for the heads up that the note radio didn't work. Also, the new official update didn't fix this issue either. Maybe I'll just have t-mo replace the device since it's not happening to everyone. Thanks all for your input!

Quick question.
Did you De-bloat your phone? Ie did you remove any apps from the system directory?

Not since the last time it returned from Samsung. And it's completely stock and unrooted right now.

I did a factory reset and the wifi came back steady for the past day I was slot more selective with my apps as I think this may have been the issue.

I'm glad this worked for you. I can't tell you how many factory resets I've done and it fails every time within a day. I bit the bullet and did a t-mo warranty exchange. Seeing as so few people actually have this problem, I'm chalking it up to my having bad luck and got a lemon. I hope the new one works fine.

I'd rather have a new one then the same one fixed lol

[Q] Wifi Calling Issue

This is my Orignal post:
I do have a slight problem that I have not been able to find a solution for. When I am at work I have wifi calling on all the time because I don't get good cell reception. We have hundreds of access points all of them overlay one another so students don't loose Wireless connection. When I move around and switch from one access point to another the wifi calling just stops or tries to connect to the access point it originally connected to. Now I find this odd because I have set these access points up like I explain above so they overlay just so this would not happen. Now when I was on Stock ICS non rooted the Wifi calling didn't drop at all. I doubt you can test this but I am hoping you can point me in the right direction on how to resolve this issue.
A person wrote back to me and said this
(My guess is that it has something to do with how the rom polls for new access points. Polling may be set low to reduce battery consumption and causing problems for you because of it)
Which makes sense I am wondering if there is a easy tool or a app to check this out

I can't even get WiFi calling to be stable on ONE access point....

Weird things after official 4.3 update

Hi guys,
Few days ago my S3 received official 4.3 android update, and weird things happening after that.
When I connect to internet, via wi-fi or data, phone automatically download a small file named "files.zip". And it happening every time I turn on wi-fi or data... I can`t find this file in downloads or anywhere else. When I try to open, it says "cannot open".
Second weird thing - browser often redirect me to a advertising or span webs. For instance, I try to open youtube.com, it opens different web with advertisement.
Anyone have an ideas how can I fix this?

We need proof screen shots video something

He stated he can't find the file, BUT when he tries to open, it say cannot open file???? How weird is that.

damn your luck were still stuck on 4.1.2 if your having the issues you say you are with what sounds like maleware. have you installed anything to check phone. over here we have apps like lookout security. i kno nod makes a phone app. you could always do a factory reset back to out the box state. reinstall apps one by one to check it out. sound like you have a app with crap in it.

Factory reset helped to solve "files.zip" autodownload problem, but phone is still laggy. It takes 3-5 seconds to turn on screen when I press power button in sleep mode. Applications become laggy. I will try to reflash 4.3 via KIES, if the problem remain, back to 4.1.2 will be optimal decision.
Thanks for help guys, and sorry again for getting lost in galaxy s3 forums

Getting no signal when calling.

Hello Everyone,
I am running the Virgin Rom with Ktoonsez.
I have been trying to find out the solution for more than two week but cannot find the solution. I got this strange problem in my phone, When I put my phone idle I get the full lte signal but however when i try to call someone all my signal get disappear but the strange thing is i can still talk to that person without the signal. As soon as i hang up my phone i would get all my signal back, when i get my signal back i can do normal browsing, watch video etc. I mean its no major issue, I was just wondering whether if there is any solution to get any signal bar back.

More device details please friend. What baseband are you on? NB4? If not, then you need to be on NB4 modem. If so, then it's possibly a kernel related issue I suggest flashing the latest build of Ktoonez kernel for AOSP, be sure to flash the right one for your phone. Example, don't flash the TouchWiz version

Sounds like it's working as it should! LTE cannot process phone calls so the device switches to 4g or edge depending on your area's reception. after the call is terminated, there is a very short delay, and you're reconnected to LTE (if there is reception for lte where you're at)
The device (depending on your settings) will try LTE, then 4G, then last resort to Edge when it's not on a call and just idling. It will connect when your device wants to access the internet or whatever, and selects the proper frequency (or mode) and use that for the connection..
check Settings/More Networks/Moble networks------ then under Network mode, you will see the connection choice.
if you tap on the network mode, it will give you different connection choices.
If you want LTE, you have only one choice and it downgrades itself as required as explained above.
you can save battery power by going to a lower frequency (like GSM only - which is edge Edge)
hope this helps you understand!
Aloha!

I want to flash the NB4 modem since im having the conection and do know how to use odin, just curious how to flash the modem as a .rar, I thought it had to be a .tar. so I felt it would be better to ask first before I brick my phone. I used the download for "Insane kit kat" I even unzipped it to find it still in .rar format

If you properly unzipped it and placed it in the phone slot of your odin program, you should be fine. Most people fail with either unzipping or placing it into the correct slot which in this case is the phone slot and not the PDA that you would use for a lot of other functions.
