[Q] Problems with Mobile internet - Galaxy Note II Q&A, Help & Troubleshooting

I am facing a very peculiar issue that makes my mobile internet dysfunctional. Whenever I switch from 2G/3G to WiFi and then switch back to 2G/3G from WiFi, the internet refuses to work unless I restart my phone. Once, the phone is restarted, it works like a charm again till the time I switch to WiFi again. Sometimes though, 2G/3G would not work even if I do not switch to WiFi. Also, rarely, it still may work even as I switch back from WiFi to 2G/3G. This issue has plagued me since a long time and is sometimes accompanied by call drops.
I took my phone to a Samsung Service centre but it wasn't of any use. They do nothing except reflashing the stock rom. It did fix the problem for a while but in an hour or in a day(or in some random time duration) the problem resurfaced. I took my phone to the service centre, just to get this problem fixed. I have tried switching between different modes in settings: GSM/WCDMA/auto etc
I also tried contacting my mobile carrier and got my sim card changed. Therefore, the mobile carrier is not at fault (Internet works flawlessly after I restart, remember?). How do I fix this? It is really irritating to restart the phone every time I need to use the internet. Please help! :-/

Maybe try flashing a different modem. I had various data and call issues on my i9300. After flashing 10 or so different modems I found one from aveuropean carrier worked best. Im in the uk btw

Thanks for replying thedadio!
But I've never flashed a modem before and have no clue which one to choose. Is it same as flashing a custom rom? Also, can I brick my device while flashing modems?

Yes its similar to flashing custom ROM. What ROM are you on and what modem are you on?

McLaren__F1, I am on stock 4.1.2. Also, I just tried flashing DDALJ1 modem (As I'm from India) and Perseus kernel. None of these steps helped me in any way. Still the same issues. :-/

Which is your network provider? I had the similar problems when I was on docomo..nw ported to airtel nd problem solved.
Btw did you try some other np's sim?
Sent from my GT-N7100 using xda premium

I am currently using Airtel (Prepaid). I haven't tried using any other np's sim though..

I have the exact same problem. I am with optus Australia. I tried different modems, different ROMs but all have the same problem. I have sent mine away to be replaced and am still waiting for the new one. Very frustrating problem.

I'm not sure if they'll replace mine. It has been almost 6 months since I bought it..
How do I solve this? Any clue anyone? :|

My Note2 does this sometimes & only fix is a restart.

try soft format may its helpful

Not a fix, but toggling airplane mode on and off does the job for me.
Interestingly this happens to me only when leaving one particular WiFi access point.

i got exatly same proplem, 3g not working after leaving wifi of my workplace, but when im home i have no proplems if i decide leave my home network.
could it be related to radio type wifi has?? my workplace still using old hardware with radiotype of .g and leaving that network "kills" mobile network and i need to reboot phone, but my home network is .n and im not having proplems after leaving it. if its related to wifis radiotype it should be easy for someone to write script which reboot mobile network after leaving those wifi networks.

Doesn't work for me. This problem is strange. :-/

No one has a solution for this problem on XDA?

Did you use the NFC to scan anything by any chance? I don't know if it could be related but my phone started to have issues around the same time I bought some NFC tags and started programming and scanning them.
I still haven't got my replacement phone back yet. But I'll let you know if it still has issues in my problem spots. Than we'll know if the problem was with the phone or just this model.

Nope! I haven't used NFC at all.
Ohh, okay..Eagerly waiting for your response! *Fingers crossed*

Tested replacement phone today and the problem seems to be gone. The signal was actually stronger than all my previous phones.
This issue could be a hardware problem as from what I have searched on the net it seams to affect only a few people. I just hope if I root the phone the problems don't come back.
Maybe you could try send it away for repair if they won't replace it.

Looks like I spoke too soon. The issues are still there. While waiting for my replacement phone I was using an old HTC wildfire and had no issues with the data connection so it must be an issue with this model.

Mobile data issue??

Hello everybody,
my galaxy nexus randomly loses mobile data. This issue is not present with wifi connection but only with mobile data.
The only solution is make a reboot and after that mobile data begins to work again.
I've tried to update radio (now i've got XL1) but the problem persist
I also flashed a new rom ARHD 2.1.3 and for now no problem but i've flashed yesterday, so I'm waiting to see if the problem is solved or not.
I read in the forum that i'm not the only one, any solution about this annoying issue?
thanks
Hi,
can confirm the same issue, overall signal seems very poor now I'm at ICL53F.
can you pls paste a link for ARHD Rom? i want to test it, but can't find it using search...
thank you

Do you use JuiceDefender?
Same happens here, and I exchanged my phone to see if it would stop. At least it hasn't happened as much. My advice would be to put a toggle on your homescreen for airplane mode. That always remedies it rather quickly and is a workaround until Google gets on it.
Sent from my Galaxy Nexus using Tapatalk
I second the Juicedefender guess. That app turns off my data routinely, causing a delay of up to 2-3 minutes waiting for it to re-connect. I had to get rid of it for that reason.

i'm thinkg about to send my phone at samsung assistance, but i'm not the only one, i also think that google can fix that with a future update, but for now this problem is terribly annoying
I have similar issues but mine only started showing up since I started using Tasker to turn mobile data off when phone screen is off and turn back on when phone is unlocked.
One way I can get the data to work again is by turning aeroplane mode on then waiting around 5 seconds and then switching aeroplane mode off. That works for me. Another way I usually go about it is to switch my screen off then on again and my Tasker script disables and enables mobile data.

It's a common issue, people say ARHD eliminates the problem, not sure about that since im in love w/ franco and running AOKP milestone 2. Its a software issue, and will hopefully be fixed in the future. It happens irrespective of radios. toggling wifi on and off resets it 90% of the time
Also theres about 50 posts on this so please follow the rules you had to watch when you joined the forum and search next time.

Wifi not working properly

This is strange, my wifi works but then suddenly it only uploads (only green arrow lights up) and it will not download (orange arrow will not light up). I can disconnect and reconnect and I get some service, but then nothing happens.
I've tried the following:
Rebooting the phone several times
Restarting the router
Changing from DHCP to Static IP
Turning off the new open network notification
Clearing data from Google Play store
Disabled wifi power save with *#0011#
Nothing seems to fix it. What is going on?
READ BEFORE YOU FOLLOW ANY OF MY INSTRUCTIONS!! U HAVE BEEN WARNED I AM NOT RESPONSIBLE IF YOU SOMEHOW DAMAGE YOUR PHONE!!!
OK so let's go straight to Ur answer.... Let it sit for a while after it boots up (a minute) with Ur wifi on. so restart the phone while wifi is on and let it sit for a while... If Ur using a wired connection with a wireless router disconnect the wired modem then the wireless and wait 10 secs and reconnect the wired first and let's all the lights go green or whatever color they show u its ready and then connect the wireless router and try to connect to it.
If that didn't work and you don't have your phone rooted then flash the only time that we have for now. That should fix the wifi issue.
If it doesn't work try to go back to stock and let it sit for a while without touching it and if it doesn't work then the phones defective but keep in mind that if you went through the root process that if you send it back without erasing the flash counter your warranty will be voided so be aware of it. I don't know if there's an app compatible with the s4 so if it's not rooted then replace it just to be safe.... It's your choice
Sent from a phone better than yours!
My phone is not rooted.
What did you mean by flashing the time?
How do I erase the flash count if I decide to root later?
Thank you for your help. =)
------edit------
The method -- sans the flashing the time -- seemed to work, but then the internet stalled again. This is happening on two S4 phones. My other phones have no trouble with the wifi, my pcs have no trouble with the wifi. What are the odds that two phones aren't working? Nobody else is having this problem?
I have already made a thread with the sane issue. You're not the only one facing it. A lot more people are too. It might be a software thing and might be fixed in the next update. If not, exchange it

What router are you using? D-Link DIR-655 seems to be most popular one people are having trouble with. What mode are you using (a/b/g/n/mixed/etc)? Mine only works with Mixed n and g mode. When you turn off the wifi, does it actually turn off (the green indicator will dim but should actually go away when it's off)? The stock rom seems to want to keep the wifi on at all costs... not sure why! Mine is very stubborn and takes several tries before it actually turns off and says "turn wifi on the see available networks." In order for the *#0011# Power Save Mode Off setting to work, the WiFi needs to actually turn off then back on. I have to toggle airplane mode sometimes just to get the wifi to turn off.

It shuts off when I save; I put the settings as you suggested. I'll test it.

DGL-4500 is a D-Link, correct? If it is a D-Link, I'd make sure you are on the latest firmware for it and try various mode settings (disable mixed modes, 2.4GHz or 5GHz only, WPA2/TKIP only, etc). This post details a solution to my scenario; maybe it'll give you some ideas.
I have d-link router too and wifi working just fine

Yeah, it is a D-Link; not a Linksys. I tried what you did, it seems to be okay so far. I have the latest firmware. I still think this is a problem with the phone. Do you think an update will fix it?

Yes, it's definitely a problem with the phone. I've spent the last several days researching and trying to find a permanent solution. It appears to be a software issue but I've yet to explain how wifi works just fine for some and not for others.
Any solution to this yet without messing with the router setting. I have this week left to get a full refund. I doubt exchanging it would make a difference. Plus tmobile is out of stock and stores won't allow exchanges since I bought mine online.

[Q] Android 4.3 wifi problem

I know this has probably been asked many times before but i can not find an acceptable answer. My WiFi will not automatically connect to known WiFi spots i know they are solutions to try like turning wifi optimisation on/off and you can always manually go into wifi and it will connect, but its not right it is not how it should work. I'm wondering if it is linked to hardware as in a certain batch of components not working properly with the software. Anyway is there a permanent proper fix other than flashing back to an early release. Also I have tried many 4.3 roms including stock and they are all the same

Had the same issue. Having success with a Tasker rule that turns off wifi for 1 minute when wifi connection is lost and then turns it back on. This seems to reset the wifi so when I return to a known wifi, there is a reconnect. At wost have to wake the device (hit the power button) and then wifi comes alive.

Thanks for help I've decided to go back to 4.2 for now. It really bugs me when something doesn't work as it should and refuse the 'workarounds' as a matter of principle. Does anyone know though if it is a hardware batch kind of problem as it just doesn't seem to make sense that some people have the problem where others do not. I hope 4.4 doesn't have the same issue.

Having the same issue here on my toroplus. I've noticed three different behaviors: automatically connects, connects right after screen turns on (before unlocking), and doesn't connect until I tell it to "Connect". I've read that some people have reported the issue on the Nexus 4, but I don't know if that means anyone is working on fixing it...but being on multiple devices, someone that can fix it ought to notice it, right? I hope so; it's definitely starting to annoy me too!
Its annoyed me to the point I think 4.3 is unusable. I have limited data usage and with my very useless memory I keep using it up as I've forgot to manually connect to WiFi. I've even tryed looking through all the system folders to see if I can edit some setting but I don't really know what I'm looking for.

Recently tried 4.3 again with the same problems as usual. Buuuut after a week of using it the WiFi issue seems to be fixing itself!?!?! More and more often its connecting by itself yet I have not changed a single thing. I am on stock unrooted 4.3. So maybe its just a case of a bit of patience.
Sent from my Galaxy Nexus using XDA Premium 4 mobile app
No, I can't confirm that. I've been using 4.3 for at least 2 months and the issue hasn't fixed itself the least.

[Q] WCDMA Mobile data issue.

Hey everbody. this is my first post on here. and I have a really annoying issue.
OK, i bought an unbranded Galaxy Note II N7100 4.1.2 jelly bean couple of months ago and that issue seemed to be there since the beginning.
It's that when I'm connected to internet through mobile data on WCDMA, all of a sudden the "received" signal (orange arrow) won't flash any more while green arrow flashes every two seconds and i have no internet access no matter what i do, the only thing that can temporarily fix this is that i restart my phone and then the internet is perfect again for a not certain interval of time and then the issue happens again, it won't come back until i restart the phone again.
Sometimes it could stay for 12 hours before it happens and sometimes i could keep restarting my phone every five minutes, it's really annoying.
I've tried all the known tricks like hard reset, deleting all apps, i disabled so many services or apps that may cause this problem, I disabled all syncing apps, i deleted, re installed APNs, i changed my SIM card and finally i subscribed for another network provider and it still happens
I'm really at a loss, I don't know what causes this problem.
Is it a hardware issue? but if it was a hardware issue, it wouldn't work at all even after restart, right? is it some bug in the built-in 4.1.2 jellybean?
And i also may say that i receive calls normally, the WIFI works perfectly and the GSM mobile data works all the time no problems, it only happens on the WCDMA ONLY or the AUTOMODE.
The H , H+ or 3G sign is up there but the orange arrow all of a sudden won't flash and no internet access at all untill i restart the phone.and this issue may start to happen even if the mobile data is off all day and when i turn it on BOOM the issue seems to be there even before turning it on.
I hope you guys can help me with this...thanks

Flashing a custom ROM is really easy, and there is no way u can brick your phone if you do the steps correctly.

Need more info....download samsung phone info and post a screenshot of the firmware tab. If your bootlader and baseband dont match, theres your problem. If they do, try reflashing stock (twice) then doing a tactory reset from the stock recovery right after. If after that the issue is still present....probably something else.....mabey hardware related. Good luckl
Do you use bluetooth? I had a very similar problem and figured out that the only time I had call audio was when I was using a bluetooth headset or the bluetooth in my car. I don't know what sets it off but I've done some searching on this problem and it appears to be common among GSM GS4 owners, and even doing stuff like a complete reset doesn't fix it.
The one fix that I did find, that helped some people, was to go into Google Now and disable "Okay Google" detection from any screen. Several people found that that worked. But I didn't have that feature enabled anyway so it didn't apply.
I don't know if the same problem occurs with CDMA GS4s; my wife has a Sprint GS4 and doesn't have the problem but that doesn't mean it doesn't exist. I think it was just AT&T and T-Mobile GS4 owners who reported this.

I don't have Bluetooth, I've tried it with a wired headset and even that didn't work, but what's so puzzling about this is that my calling works fine with Facebook messenger calling feature, hangouts and things like that

Edit:
Nevermind. It worked twice then I tried calling a different phone and it broke again. I will keep searching and update.
Original:
I have had this issue intermittently for the past year. It was fixed for about 6 months then two weeks ago started occurring again. Today I flashed a new Rom (PacMan) and the M919UVUFOK3_M919TMBFOK3_TMB firmware. That did not fix it. I was connecting to a 5Ghz WiFi so on a whim I forgot that network and made a call without WiFi enabled. Call worked!
So I connected to my 2.4Ghz WiFi and it is working again. I would try turning off WiFi and see if your calls go through if so it could be 5Ghz or the router...maybe a forget network / reconnect to network will fix it consistently.
Hope this helps you and if anything new comes up I will let you know.
So an update. I finally just gave up on it. My wife had an old phone I remembered (from 2 - 3 years ago) that was ran over and the digitizer broke. I just took her guts and put it in my phone and now it magically works. Hopefully it stays that way.
Should have done this years ago as my phone would no longer charge with the USB Cable nor was my SD Card accessible. Now it is all functioning right again.

So after flashing stock NB4 twice.....and factory resetting after from stock recovery, your still not getting call audio?.....doesnt make sense....try again and make sure the bootloader and baseband match.....and dont reboot into download from the OS.
For anyone having issues with no call audio through cell service but for some reason it works through data calls through whats app or facebook messenger, etc ,i have been having the same problem for awhile now. I believe i have traced it to be a hardware issue with the middle frame, when looking at the phone with the battery cover open on the top right over by where there are two markings R1 and L1. There is a module there labeled J-AT TMGA 7-3. When i was having issues i noticed that if i put slight pressure on that module my audio would fade back in on the call but if i put too much pressure it goes away again. If it is a hardware connectivity issue it would explain why slunked was able to get his phone working again by changing the guts in the unit. Im currently waiting for a middle frame and a blue cable for the antenna to confirm if this is indeed the issue.
