[Q] Network Issue - Galaxy S III Q&A, Help & Troubleshooting

Hey guys I've had my S3 for a few months now and after a few days from purchasing I received a WiFi problem in which the device disconnects from the connection and reconnects after a few seconds and this happens simultaneously.. I didn't contact Samsung then because I thought it would be fixed after updates and installing a few ROMs and tweaks.. But I bore with it too much now for 4 months and it is really annoying me.. The recent problem now is that it connects to the WiFi and HSPDA+ but never sends or receives information, like i can't use data/internet at all.. i tried many things but it never worked, not even updating to the latest 4.1.2 helped solve the problem..

Some people including myself are having connection issues when gsm/wcdma auto mode is selected...phone is stable when gsm only is selected..after comparing with 2 other phones,i can confirm this behaviour dosent happen on their phone..and i have to sadly say something is wrong with my phone..why dont you do a little experiment..try selecting gsm only mode and see if your connection is stable..maybe you are having a defective phone like some of us here...untill today i cant figure out if its a hardware fault or some weird software glitch.

Many people including me are having this exact same problem. I am suspecting the modem software, and hoping it will be fixed soon. But please note I also held hope for almost a year that GPS glitches in the first galaxy were fixable with software, and now we all now it wasn't.
I'm having the EXACT same problem! Out of nowhere my 3G connection is 'lost?' and I only see an upward green arrow.. i have to reboot to get this right.. but after a short while.. same problem again!
I live in The Netherlands... I wonder what the problem could be, but even better! THE SOLUTION!!

[Q] Wifi dropping even when it shows it's connected (w/ Video)

I've had two Galaxy S II phones now, and I've had the same problem with both devices. The phone's wifi is great -- when it works. Although I noticed that the death grip lowers the wifi signal bar, I can still browse the internet and download apps just fine.
The problem is that, at times, the phone will show wifi connectivity and yet, I can't browse the internet or access the App Store. I'll have to shut off the wifi multiple times and even this doesn't work 100% of the time. Shutting off the phone and turning it back on works 100% of the time.
Since this has happened to two phones, I'm beginning to question whether I have an issue with the wireless router because I have not come across this as a prevalent issue. At the same time, my laptop and a family member's iphone doesn't have the same issue.
Anyone else having this problem? Or have suggestion for fixing the problem?
Thanks
Here is me showing the problem on video:
My roommate and I both have the Galaxy SII and he constantly has problems connecting to our wifi. The only difference in our phones is his is rooted and mine is not. I plan on rooting my one of these days but would like to fix the other issues I am having first.
Mine isn't rooted, but it still has the connectivity problem.
EDIT:
I may have found the the solution. Probably unique to my situation, but what I did was disable WPS on my router. It's a medialink router and I thought I had disabled it (per instruction) but it was on. Perhaps that was the issue. So far, no problem.
EDIT:
Nope, the wifi has dropped again. By dropped, I don't mean it drops in the middle of browsing. It seems to drop after I've stopped using the phone for a while. I've already checked to see that the phone is to never turn off the wifi when the display is off/sleep.
Arghhh
same exact problem.
wifi on moto surfboard sbg6580
did the static ip fix continue to work?
Any phone is the same.

Don't have any issue with wi-fi , mine is rooted on stock rom
i have no issues with wifi on my sgs2, i have wifi on 24/7, and on wifi proabably 50% of the time. it connects and disconnects when supposed to, picks up on cell data and drops when its supposed to..
fwiw, my GF has an iphone 4, she had problems connecting to the HOME wifi, but no where else, i updated the firmware on the router, same problem, i swapped out the router for a spare a friend had, and setup a second access point on the same network, just called it the same SSID but put a "2" after it.
her connectivity problems went away, immediatly she noticed a difference and has never complained of a drop since...
try different encryption methods, if you're using wep, try wpa, try a few different things.
also try a firmware update, you might lose your settings during a firmware update, but there is usually a backup/restore option you can use. backup your settings before flash, then restore after. if you have access, for at least testing purposes, hook up another router and use it to connect to and see if the same problems persist.
No problems at all connecting to a WHR-G54S running Tomato.
The Moto Surfboards are known to be flaky.
I had the same problem. after getting another one I found out that if I didn't download so many apps at one time the problem mostly stopped and after running a couple weeks, I haven't had the problem with connection since. I'm not sure it will help, but I did a factory data reset and reinstalled the apps one our two at a time (it's frustrating, I know).

[Q] Samsung Galaxy S3 Data freeze.

Hi,
I'm new to the forum so apologise in advance if this is a stupid question.
I recently bought a Sim Free S3. I haven't rooted it as i'm quite happy with the stock os for now. Everything had been working very smoothly on it. But since getting the over the air update for it my data signal randomly drops out or freezes. It seems to do it over WiFi too. It does this even though it shows a wifi connection or with the H+ visible. I've also noticed it cycle through H+ to 3G and back again.
Sometimes the signal works again on it's own and other times i have to switch the phone off and on aain.
I find it happens on tweakdeck the most but has also happened whilst browsing the net.
Do you think this could be linked to the update or could this just be a coincidence and there's an underlying hardware fault.
Let the new update run for a little bit...let it settle in
It might just be the spot u in and I doubt its the phone
Might be uodate but how long u been on the update?

Think the update came through on Tuesday.
Will give it a few more days to settle and see how it goes.
Thanks.
Still having an issue with this.
My internet worked all weekend then today started to fail on me again today.
The phone shows a HSPA connection but will not download any data.
I know it's not the network as my wife is on the same network and is having no issues.
Any help will be greatly appreciated.
Same problem
I am having the same problem here. I just bought SGS3 about 3 days ago and I started noticing data drop out yesterday. I wish someone could help me. I was hoping the problem to be solved by the time we get firmware update.
BTW, I am also having problem using usb tethering or wifi hotspot. After using usb tethering for about 10 minutes, it stops connecting although the phone still has data connection.
Is it hardware or software problem???
Thanks!!!
having the same issue after power saving goes on i lose h+ until god knows when

Connection Issue [MoKee 51.1 / Android 5.1.1]

So I am quite sure that I've got a weird issue with my Redmi Note 2. To make it fast I will just list the issues.
Phone logs out of all networks (Wifi and mobile data at least every five minutes).
Sometimes it just 'decides' not to receive or send data, wheter it is connected to the internet or not.
Mobile data is never faster than E, even within my monthly data limit and in areas with high speed mobile data.
Is very slow at times (and crashes approx. once a day).
Does not react for some few seconds every now and then (makes typing impossible/remixes music...)
The main issue is the connection problem. My provider combines two mobile data networks, so that the phone thinks it is in roaming sometimes. Yet all of this was not a problem at the beginning. The connection issue just suddenly appeared (after I was on vacation and used roaming). Not sure, if there is a connection to that, though. I already asked a more tech savvy friend of mine, but got no solution out of that. So far I have tried:
Installing a new operating system (nothing changed eventhough that exact OS worked perfectly on the same phone my buddy had).
Googling the issue and try to play with the settings to get it working properly again (again nothing changed).
What I don't get is why such an issue would suddenly just arrive and that apparently nobody else had that same issue. I would be more than happy about any help I can get. Besides the issues I like the phone (and don't want to have to buy a new one).

Hi,
The same problem is on my phone. Due to this problem, I couldn't use the phone at all, I bought another phone. Now my device is in the drawer, no different from zero. I have tried various roms, including lineage, I changed wifi antenna as hardware. The problem continues. Is there a solution to the problem.

No mobile internet after wifi disconnect

Hello everyone
A week ago I bought my Galaxy S9+. Sad to say that I've been having connection issues. When my wifi connection drops neither apps nor browser can connect to the internet even though the 4G logo is present at the top bar. To resolve this I need to do a reboot and then everything works normal.
Anyone have an idea what the problem might be?
Does this seem like a problem I could fix myself or should I return the phone (which I prefer not because of the hassle)...
Hi, have you found any solution to your problem? I have a similar one and it starts doing that after the last update in June, before it used to work fine.
