[Q] T Mobile 3g Random Data Drop

Hi,
So i own a nexus 7 3g and use the t-mobile data service and i am hoping you guys can help me with these random data drops i get.
I will bring my tablet to work, put it in my book bag and drive to work, and when i get to work, the data signal is gone and its disconnected from t-mobile.
The only way i know how to get data back is restarting the tablet.
I was hoping there might be another way to get data back without rebooting, or find a way for this to stop happening altogether so i dont lose data randomly like this while i travel or leave the device unattended for a few hours.
I have never owned any GSM devices besides the nexus 7 so i am not to familiar with troubleshooting or any little tinkering i need to do with a GSM device/sim card etc.
So any ideas/help will be awesome and gratefully appreciated.
Thanks in advance.

There maybe problem because of apps like juicedefender which disables network in ideal/sleep mode ,So unistalling such apps may help you , BTW Are you sure network is not an issue ? Because even i have 3G Nexus 7 , i am also facing connection issue, My networks disables automaticaly anytime, when i use Wifi it disables my Sim network connection, It means i cant use internet without wifi though its 3G model I have reported the same to my nearest Asus service centre they looking on it , They told me there will be setting for data dropping , If i able to find its solution then will PM you.

Hi
Thanks for the helpful tips. I'm pretty sure i don't have any battery saving apps, i deleted the few i did have.
I don't have any network issues. It seems it only turns off when in traveling around with it. Its really weird, and i am confused as to why it just goes away only when im traveling with it.
It does get disconnected from the internet when on wifi at home and stuff, but i still have bars in the signal icons moving and showing me that i am connected to t-mobile service.
But when i am dealing with this issues and have no data, the icon is empty and it tells me i have no service.
Maybe just toggling airplane mode might work, ill try that next time.

i tried toggleing airplane mode, no luck.
It may be the connection, but is frustrating i have to reboot every time just to get data back. Even if i toggle data in mobile data it wont work.

Trouble with WiFi, disconnect continuously in tab 4 wifi version

Hi, a few days ago, i have trouble with the wifi in my tab 4, model sm-t230nu, has not been dropped, only and maybe, i root and install a couple of apps, inclusive with the modem near, 50cm aprox, the problem is the same, every 5 or 6minutes the tablet cant connect with the wifi but the little icon of the signal still appear with excellent signal..... to resolve this problem, i need to disconnect the wifi in the tablet and recharge this.....
what can i do?

??? anybody could help me?

Just got off with samsung support try this http://tinyurl.com/nfbgxds

I have two of these devices and they both do the same thing as you are describing. They are "connected" to the wifi but they will no connect to the internet. This happens over and over and over. It can happen on both devices 7-8 times in a few hours. I called Samsung and they said it was my router. I called AT&T and they said it was the devices. I also have a Tab3 10.1 and I never have this problem, All of other wifi devices do not have this problem. It has to have something to do with the SM-T230NU. I noticed there was a software update for the device this morning so I am hoping there is a fix included.
If some others can chime in that are having the same problem with the SM-T230NU maybe we can at least get Samsung to acknowledge the issue because right now they are in denial.

I'm not getting disconnects (at least on this first day with the t230nu) but the WiFi signal strength is considerably less than my Note 3 in the same room as the Tab 4. Probably related?

I actually get total disconnects. I'll be playing a game or browsing the web and suddenly no internet connection and about a second later I see the toast message that it's now connected to Wi-Fi. If I reboot the tablet, it seems to work fine again for a while, but after a day or two, it does it again.

check build prop
I just received this tab 4, 7 inch and I am having this same WiFi connection issue. I have looked through the build prop and found two conflicting lines.
ro.carrier=wifi only
And
ro.carrier=unknown
Now the WiFi only line makes sense since my tab is a WiFi only model, but the unknown line usually means an open type data carrier. I have commented out the "unknown" line and will post back if it makes a difference.
So far it has been little over a week and I have not noticed the connection trouble since making the change.

by what do you mean by this? Did you change something on the build.prop coz I am also experiencing the same, I've been to Samsung service center and what they just did is update the software that did nothing but to do the same thing. Would you mind telling us a bit more of what you did please???

My 7" suffers from this same annoying problem. Can this be Fixed with the build.prop without being rooted?

no sorry making changes to the build prop require root.
and commenting out lines simply means to add a pound symbol to the begining of the line.
so for example
ro_carrier=unknown
will become
#ro_carrier=unknown
but i beleave the fix also requires setting your ip address to static and not automatic dhcp

Did anyone try my link? Solved my issues works like a champ now!

If your rooted use an app called build prop editor or some sort. Then just find those and set them as said in the post.

when i did the # symbol it still didnt fix my wifi problem

This link isn't working for me. Do you recall the title of the support document, or what the steps were? I'm having this problem too and would love to see what Samsung recommended.

Having a very similar problem
When I connect my GT-P3110 to the internet and it says "connected" then the very second I open a game such as Nova 3 the network icon disappears and the internet stops working but the minute I go back to the home menu it reconnects to the network
this tab is rooted so I can edit the build.prop but I was wondering if this is the same issue or not
any help is greatly appreciated

"Ready to connect when network quality improves"

Hi guys,
Getting this message upon connevting to virtually every wireless network sinse rootibg my phone, is there a root tweak to disable betwork quality checking ? On a G900F
Thanks

Anyone?

You should be able to turn off smart network switching under wifi settings that will solve it.

Nice one thank you! I will see what happens!

turning off smart networks helps, but if the wifi signal is too poor it will not connect anyway

u cannot change that.

ready to connect when network quality improves
We have two Galaxy 5s in our home (AT&T and T-Mobile). Both just started getting this message last night. "ready to connect when network quality improves"
Its multiple access points, multiple networks. Eating battery like crazy. Dropping and reestablishing connections to WiFi every 15 to 60 seconds.
Pain in the @zz

Turn off "smart network switch"
I also started getting "ready to connect when network quality improves" messages constantly as the network connected and disconnected. Turning off the "smart network switch" option fixed the problem. I also leave the annoying Samsung Connections Optimizer turned off.

Smart Network Switch Off?
I just got my S5 about 6 weeks ago. I have had NO issues until this week. A few days ago, even though wifi notifications were turned OFF - I kept getting this "connected to network name" message on the bottom of my phone. When I went into wifi settings this morning, I noticed it would switch from connected (very strong signal strength) to "waiting for signal quality to improve". It constantly goes back and forth - 5 seconds or so on each. This is not an issue on any other device connected to the wifi router at my home and I just tried it at work - happens here too.
I checked to make sure wifi notifications were off - they were - but the pop up still appears over and over. I think that's another issue separate from this because if notifications are off you should not be getting any!
I have done as suggested here and turned off the smart network switch, however, does that now mean that I will be switched back and forth every 5 seconds from data to wifi? That defeats the purpose of connecting to wifi to save on monthly data plan charges.
AFTER noticing this problem this morning, I went to see if there were any software updates - there were (Lollipop). I did download that, but no change.
How does turning this off affect where my phone pulls from? Uses data or wifi?
Thanks for any help!

+1 with exact same timelines/symptoms and upgraded to Lollipop and no diff too.

I started getting this message on my S5 last night! The connection will hold for about 10-15 seconds before reverting to LTE.
Tried resetting router settings, playing with different wireless settings - changing channel width and turning the visibility on and off.
Then "forgot" the network and readded it again.
It seems to be holding a stable connection without it dropping and was able to download a few items from the play store without dropping.
Will update if it changes.

Same here S5 900F

Me too - I've been searching for weeks to figure this out - tried every known fix .... nothing has helped. I've even reset/changed/updated my wifi settings on my router. Nothing has helped. My S5 is the only one that has this problem. Other phones in the house have no problem - S4 and others.... I just don't know whats going on. I maxed my data avoiding this issue - but I really need a fix for it.

This problem was driving me insane......I had it and managed to fix it (hopefully been going ok for three days now) I have a samsung Galaxy S5 on EE.....I backed everythingh up and did a factory data reset. Hope this helps.

I have a Galaxy S6 and have the exact same issue. I have called Samsung, my carrier (US Cellular), and tried a local place to get it fixed, but no one has ever heard of this issue. Amazon Photos was hogging a lot of bandwidth and backing up on wifi only so I stopped using that. Still not much of an effect. Using FB or a video is almost impossible because they won't load or refresh. I've tried all of the suggestions, but don't see a final fix. Can anyone help? This is my second S6 with the issue.

Note 4 Disconnects from network

Hello,
I own a N910CQ for 1.5 years now.
Two days ago, suddenly my phone started to disconnect from the network. Neither incoming/outgoing calls nor mobile data works *seamlessly*. The network connects momentarily and disconnects not so long after.
Some non-authorized fixer said that that was a typical Note series problem and asked me if I wanted to proceed further because he had to remove the front glass to try to fix it. I did not allow him to do it so I am stuck with a working but useless Note 4 right now.
Have you ever encountered such issue and if so how did you overcome it?
Thanks in advance.

Go to settungs/back up & reset and factory reset erase everything and try diffrent sim card also.maybe software or sim card issue.

No luck.
I switched from Polish ROM to Turkish one (both 6.0.1), do you think modem files might be causing such issues?
Fixer said nothing visible seemed like the root of the problem and that if I took it to a Samsung Service they would most probably like to replace the motherboard and that would cost almost as much as a new phone.
