Hello
I have this issue with my Sansung Galaxy S3 I bought from my carrier one week ago.
My data plan is enabled to tether, I didn't have any issue with my Atrix 4G, connection was completely reliable on it, but i do have issues with my Galaxy S3.
It starts the wifi hotspot, my computer is able to connect, but after a few minutes, and sometimes just a few seconds, computer can't navigate, and the only possible way to solve it is by disconnecting and reconnecting from the wifi hotspot.
I have tried also with other laptops and is the same.
Now, I noticed it always happens when cell phone switches from H+ to 3G. It looses connectivity while in 3G, and it get connectivity when it gets back to H+ (but the laptop keeps without navigation although Wifi keeps connected to hotspot).
I have searched and couldn't find any answer here. Is there a way to force it to keep H+ or H connection? not 3G? (because the issue happens every time it goes to 3G). I think it is something related with the power saving features of the phone but I have no idea how to tweak it.
This is International version
GT-I9300
Android 4.04
BaseBand Version I9300UBLG2
Kernel Version 3.0.15-928452-user

My device is rooted.
I am in HSPA+ coverage area.
It either drops back because the network has fast dormancy issues (you can try to disable fast dormancy through the corresponding app which requires root)
or because the network is instable.
In the second case you can't do anything at all except try another modem which might be less prone to the network stability issues.
Have you tried USB- or bluetooth tethering? If yes; is it unstable too?
I just disabled fast dormancy using FastDormancyToggle for i9300... I am going to be checking and if it keeps dropping I will try tether over USB and over bluetooth. I will keep you informed.
Thank you
Run ping from a terminal emulator and you will be able to see the dropouts

Since I disabled Fast Dormancy it has been working much better.
It switches from H+ to 3G from time to time but it doesn't disconnect when doing that.
Thanks a lot for your help. I guess it is fine to close this thread.
It WAS working better... now it is not... It is working almost the same, a little better, but keeps dropping, although Fast dormancy is still disabled.
So, I installed Foxfi, and seems it improves a lot, so it is a better Wifi tether option than the one that comes with SGS3
is anyone having a problem with the wifi after updating to jellybean for s3?
inital connection to WIFI works but after a certain period of time, the wifi stopped working and i need to restart the wifi again for internet to load. IT happens all the time now after leaving my phone with WIFI on.
Constant restarting WIFI to get connection does not happen in ICS..

No such problem for me with JB LJ5 stock or custom!!!
Might be your modem-router....
This happens to me too. It's fine for me at work, but when I'm at home the wifi fails to connect after some time. Are you using dd-wrt at home? I am and I'm wondering if that's the issue.

I find that having my wifi set to always on in advanced I get better wifi and slow drain, having it on wifi off while asleep makes your wifi keep disconnecting and reconnecting. Best way is to switch wifi off when you don't need it.
Also some battery saving apps I've found to stop wifi and need to keep reconnecting, this has to be changed in the settings
wi fi dropped

Hi, Mine is Galaxy Note 2 i317 with Jelly Bean 4.1.1. I did have similar issue. I took two smart phones to Target, one is ICS 4.0.3 and the Note 2 is 4.1.1.
The 4.0.3 never has any issues with wi fi connection. But the Note 2 keeps on dropping the connection. I ran an application wifi analyzer to check the available networks. It turns out that Target has so many routers that are using the same ssid, i.e. "Target Guest Wi-Fi". There are channel 1, 6, 11, etc, as well as many 5Gs. I did an alias for every available connection. Then I pick one of the stronger signal strength 5G and connected to it.
After that no connection was dropped.
The point is that you should try to connect to the strongest signal SSID so that the Note 2 won't keep on dropping the weak connection.
I have no idea why the ICS 4.0.3 can handle better than the 4.1.1 Jelly Bean as far as wifi is concerned.

Same problem!

I'm experiencing the same problem since updating to Jelly Bean 4.1.1 on my HTC ONE X. So it seems to be an Android issue, not specific to Samsung or HTC.
I connect to my home network over WIFI, everything works fine until after a little while my apps seem unable to connect to any data/internet. They just time out or come up with error messages about connection problems.
Sure enough, if I disconnect and reconnect to WIFI, everything starts working again... for a little while.
It's like the WIFI goes to sleep, but forgets to wake-up again.
And there is no indication on the phone, ie. it still shows as connected.

I echo that? It's 3 months later... has anyone figure anything out in regards to this issue?
Mine shipped with JB already. Sometimes, when reboot, it doesn't connect to my WIFI network, unless i disable WIGI connection and re-enable it...

Hi guys,
I am having trouble with my i9300, I am currently running UltimaROM v11.0 Kjata, whenever I tether my Laptop to my S3 I get full connection to my Networks Internet, however whenever I receive an email, WhatsApp message or text, I get no access to internet on my Laptop, even though both the Laptop and the S3 state that a connection has been made and is in use (by way of active tether icon on the S3 and Wireless Network Connection bars at the right of the task bar on Windows 7).
Does anyone else have this issue?
Any help is much appreciated.
Thanks

Hi, I've got an i9300 and since yesterday I dont have internet though I'm connected to WiFi. Last thing I did was playing marvel game and I was updating samsung apps and gamehub, then phone charged off and after I did charge it like for 50% I scanned for an update to see if there is available one, it showed for hours that it is trying to connect to server. My phone is not rooted and it has jelly bean 4.1.2 on it. I've triied to reset it, uncheck network notification and check for internet service. Changed keep wifi on during sleep to never, restarted the router, forgot the connectionand restarted the phone and connected to wifi again, and the *#0011# tip too, also I've tried to config manually connection. Help please.
P.s wifi works on my laptop, motorola razr and galaxy tab 2 very well
Factory reset phone .

I have a issue where when I'm using Cellular data, it will just cut off responding for like 15 seconds and switch back to 3g then H even sometimes where the App itself is requesting data. Any reasons why it would do this? I've done flashing modems and changing the network modes but it doesn't help at all.
Specs:
Samsung Galaxy S2 GT-i9100 on Cyanfox 2.0.2 Nightly 4.4.2 Kitkat.
Kernel Dorimanx 10.43 V92 Compuntio
Running Optus network if you wanted to know (In Australia)
Sometimes even the cellular data connection would cut off completely and would require waiting for like 30 seconds or turning the cellular data off and on to fix it.
