Data "stalling"

I don't really know to describe this problem better. I'm running CM10 (lately AOKP's latest build) with default kernels. I've flashed all the radios and tried a bunch of them in solid LTE coverage, I seem to have the same problem every time, which is the data seems to "stall."
It will show full signal, and then if i click a link, it will sort of just sit there, not really doing anything. Eventually it may load, or i give up in patience. Any one have any ideas?

I am using at&t stock rom and not yet rooted. Even I have the same problem. Tried to disable and enable data from the notification but did not help. But, when I turn on the wifi, and turn off the wifi again, it works fine. When wifi is turned on phone disables the data and try's to connect to wifi or shows the available networks, but I don't connect and I turn off the wifi, phone reconnects to the at&t data again and then it works fine. Not sure why.

I can't even run a speed test because it just sits there. Web pages "load" but wind up stalling. Sometimes they finish, sometimes they don't. I have no idea what's causing it. What modem are you on?

May be a good time to contact your cell phone provider for a replacement.

I was on a cross country road trip running CM9 on my GS3 and I kept running into the same thing. A temporary fix was to reboot the phone. Since I got back, I flashed SlimBean and I haven't seen the issue again.
In my case, I think its the SIM card. I used Google Maps/Navagation on my HTC G2 (using a micro SIM adapter) and my phone got HOT, I mean burn your fingers hot (upwards of 57 degC to 60 degC).
If it happens again I'm going to bring my SIM card back to ATT and have them replace it. I did some googleing and it seems like this is common with the Verizon variants of the GS3.

That's the next step... it means reflashing, and waiting for samsung to fix it though, which sucks a lot.

ive had this same problem and it would piss me off! i found out that busybox was the culprit. i uninstalled busybox and cleard my cache in recovery and all was well once again. if any of yall have busybox installed you may look into my solution.

I recently been having this issue also. But mine is a little bit different. Like my phone will say I am connected to "H" for data but when I load a Page it slightly lags switches to H+ and boom Internet works. When I stall for more then 5 minutes it switches back. I'm not sure if it's some battery conserving feature or what but I have no problem against at.

[SOLVED] Data stopped working

Running CM11 on PagePlus. I cannot access the Internet. I was able to at one time. Thought it was the Rom so I flash CM10.1 and Stock rooted rom. I reactivated the phone after the installs. Every time it says the network is connected but I cannot connect to the Internet or send MMS. Starting to think it is the phone. Any ideas?

More info:
IP address is applied. Able to ping ip address but not some other known ip address. Traceroute does one hop to 66.174.216.161, which seems to be a Verizon ISP. Might try playing with apns-config.xml. I had tried the one I had when it was working previously but did not seem to change anything.

I'm new, but had similar problems

I'm not sure the MMS issue has been resolved, as of yet. Last time I check the Development thread it seemed like there wasn't yet a fix. Someone will correct me shortly if I'm mistaken, I'm sure.
The data problem you're having is one that I struggled with for a couple weeks in CM11... I don't know how much help I can be, because I'm not really sure what ended up actually fixing it for my dINC. All I know is that I spent about three hours dirty flashing and restoring from nand backups, sometimes the full backup and sometimes just partitions. I also threw in a *228 somewhere in there. Anyways, Through persistence, and sheer dumb luck, I finally have a pretty stable data connection, as long as I don't use the mode switcher in DUbattery(that seems to mess 3g up until reboot).
sometimes it helps to toggle airplane mode on then off.

Thanks for the tip. I toggled airplane mode on and off. I could then load google in the browser but it would not do anything after that. I have a new inc and an OG Evo coming in. Might have to retire my inc for the kid to play games on. My wife is using and OG Evo with no data or mms problems on 10.1 and I am sort of digging the larger screen. Also might be able to help zach with troubleshooting cm11 for the evo (supersonic).

Glad to know it was not just my phone. I am back on your 2/17 build and was worried there was some leftover firewall stuff even though I wiped everything except emmc and sd-card before the flash.
On another note. I have that other EVO coming in so should be able to load up CM11 and do some logging for you.

So I switched mobile data off this weekend with the silent profile and when I switched it back on using the default profile my data worked.

I'm glad you found a fix! On my dINC, I don't use the profiles, and mobile data crashes randomly. After flashing the March 23rd build, it has gotten somewhat better, but it always seems to skip out when I need it most... specifically.... when I use Google voice search to either dictate text messages or navigate to an address(delivery driver). the latter is especially frustrating, because I only use the navi when I'm already out of the store and can't find something, so no alternative available. Sometimes, even when the 3g symbol is full in status bar, I'll push the voice button and it will say, "cannot reach google *** etc" :crying:

[Q] cell signal and wifi bt issues

T mobile Samsung Galaxy Note 2 sgh-t889
I rooted and installed a jedi rom about a year ago. In December my cell signal started getting spotty. I reverted to stock 4.1.2. Thankfully I was able to use my phone on wifi calling and that worked for a while. I replaced my antenna cable because it had a kink. The cable I got came with a new charging port which oddly went bad shortly after changing the cable, so I replaced that too.
Later the phone started having other issues, trouble playing back audio, it started skipping like a cd player. Then wifi would work but if I left the wifi network it would freeze the wifi signal requiring reboot to disconnect from the old network, cycling wifi alone wouldn't work, didn't ever turn off. Somewhere near this time wifi calling wouldn't even produce enough strength to make a phone call. Would sound like bad signal.
Then yesterday wifi wouldn't turn on after a reboot. Looking it up I found a suggestion to take out battery, sim card and sd card then hold the power button for 30 seconds. This worked and the post said something about it being caused from undervolting. I decided to start hacking at the phone more figuring how much worse can it get?
I started with a benchmark test, and when I compared my results to noye 2 listed on antutu the only major difference was ram, which I scored 660 about half what it should be.
Everything else was within a few hundred.
I updated to 4.3 stock with firmware from samfirmware (something like that) and had my first phone call in months!
But then it lost signal again. Then wifi again.
Deciding to keep going I tried rerooting, failed, finally got philz bootloader and new jedi master x 4.3. Installed that and had selinux issue finally solved that now wifi juat stopped being able to turn on. Tried power button trick, didnt work. Wifi still wont turn on and mobile networks still dont work.
I wrote this offline then tried wifi again and it worked.
Anyone have any idea what's going on? Anything I could fry to fix this?

Ok so suggested posts when I posted is leading me to try things. I have an empty efs folder. I just wanted this posted due to signal issues atm.
I have an old old nandroid im going to try restoring atm

So my old nandroids didn't work, so I went to my backup after this happened. I still have an empty efs folder, and no backup. Wifi is more steady however. I've tried numerous things and cannot seem to recreate any of the files.
I found some random files in the efs folder when using root explorer, but no nv data.
Nothing is being generated on reboot or rom flash except the folder structure.
Under the status in my phone my IMEI number is intact.
I'm still under the impression it's missing files in my efs folder, but I've also come across some posts stating that some phones don't have an nv data bin file?
Can anyone point me in the right direction? It seems like every google search of a term ends in failure, and a new term to search.

Cant connect to wifi anymore, tried everything!

Last week my Nexus 7 (2013 wifi) updated to 4.4.3 and it has been working fine for the last few days.
Then suddenly it stopped connecting to my home wifi, in the space of a few seconds, the signal goes from excellent to weak even though I am only a few metres away from the router. It will not automatically try to connect, but when I hit connect it goes from a strong signal icon, saying 'connecting' then back to 'saved' then to 'disabled', then 'not in range' then strong again etc. Each time I try to connect it tries to connect then a second later goes back to 'saved' without trying to do it again.
I have tried static ips, changing the settings on the router, taking off security completely, changing channels, and it acts just the same.
It was rooted and with the toolkit have tried reverting back to stock and unrooting it and although the process says it is a success, I cant get past the first page as you have to log on to a wifi network and it still is doing the same thing.
Is this a hardware or software issue?
All the other devices in the house connect to the wifi network without a problem it is just this now which without wifi is basically a brick.

I don't understand this: you updated for 4.4.3, then reverted back to stock. Can you elaborate on this point, please?
If you did not try a data wipe, you can try deleting the following two folders and rebooting: /data/misc/dhcp, /data/misc/wifi

By stock I meant flashing a stock image and unrooting it. It was stock anyway but rooted. I also tried a full data wipe in custom recovery.
The problem is, I now can't get past the first page when starting up as you have to log into a wifi network before you can get into the phone.

(1)Try rebooting your router.
(2)You may be able to bypass the welcome screen by tapping on the four corners of the screen starting from top left and going clockwise.
[Note: I borrowed number 2 from Mooem on android central. You should thank him if that one works for you.

Thank you, but rebooting was the first thing I tried.
I also just tried tapping the four corners of the welcome screen but that didn't work either.
It is becoming apparent that perhaps it has a hardware fault as I would have thought a hard reset would have cleared up any software issues.

After a few more frustrating hours, I managed to flash a custom rom on it, no joy, then flashed back stock, did a full erase, nothing.
I then sat on the router settings, took off security, changed channels, changed frequency, still the same.
The I took the back off, the 4 springs are still there so it is not a connection problem.
So has the wifi just died?
The strange thing is after most logging on attempts, the wifi signal for the router dissapears or says disabled and then comes back again about 10 seconds later.
I cant get past the login screen to put debugging on so that I can lock the tablet so that I can at least take it back to where I bought it from. The tapping the four corners thing doesn't work with this rom although it strangely did with the custom rom (CleanRom 4.4.3).
Do I just bin it and buy another one?

I don't think you need to have debugging on. Just boot into the bootloader manually and then you should be able to lock it.

If you turn off bluetooth, then all is ok. Seems to be a bug in update to 4.4.3

[Q] Major WiFi issue out of nowhere?

Hey all. I need some advice. This morning my G3 (D850) dropped WiFi connection for no reason. It says the signal is good but the network info says saved, secured. It will attempt to connect over and over again and if it does connect the signal is weak as can be and it drops the connection within 2 seconds. My coworker has a G3 also and is connected to the same work network I am. His connection says excellent where as mine said good. His device connects just fine with full bars. I'm baffled. I've already tried manually selecting 2.4 Ghz and 5 Ghz instead of auto select and that didn't help at all. I've tried manually turning off WiFi and turning it back on. I've tried turning airplane mode on and then off to refresh the connection and that didn't help. I've done a battery pull as someone in one of the android authority forums suggested that (apparently I am not the only one having this issue.), didn't work. I've unchecked WiFi optimization - no dice. There was another post on a different forum here on XDA that said turning off WiFi and then deleting the WiFi config folder located in data/etc/wifi and then rebooting fixed the issue for them so I tried that. After reboot when I tried to turn on WiFi my G3 rebooted itself. Does it everytime. SO, I had to restore to a nandroid backup (btw I'm on rooted stock 10f) to get the phone to stop hating my WiFi toggle attempts. Last ditch effort I did a factory reset hoping for an easy fix... Nope. I don't know what else to try. It was fine yesterday all day. This morning it was perfectly fine and then randomly started having this issue. I haven't altered any system files whatsoever. I really don't want to send my device to LG for warranty replacement so I'm hoping someone can help me out that may have had this issue and resolved it. The only difference between my device and my coworkers device is he is still on 10d and I am on 10f. That could be the issue I guess but that doesn't really explain why my device has been perfectly fine until this morning and I've been on rooted 10f for weeks. I am planning on flashing back to straight bone factory stock 10d when I get home here in a few hours from work but Idk if that will help or not. Judging from the amount of google search results of "LG G3 WiFi connection problems" this seems to be an issue for several people. I won't know if it's on the software side or hardware side until I get home but in the meantime has anyone had these issues at all? People have had success in changing to Static IP but I would have to do that for every connection I attempt to connect to and that's a pain in the a$$. Also, that does nothing to identify the root cause of the issue. Any help would be greatly appreciated. =)

Thanks for the reply. So it turned out my phone just randomly decided it doesn't like my work network anymore. Idk why lol. I got home and it hooked right into WiFi. Gf's WiFi and open networks as well. I call shenanigans. I went ahead and flashed back to 10d anyway though.

I am having the same issue! But it is happening in other networks too...sometimes I get the phone to connect but it only works for a while and when I check the networks it only says Saved, even if I try to connect again

Having the same issue, whether at work or home, my wifi has become near useless. I've even gone as far as trying a different ROM. Didn't work.

Same thing here

I also have tried factory reset, installed a new ROM, changed settings in my router... but the problem remains I don't know what to do anymore, I use wifi a lot!! I searched through other topics but no one seem to know how to solve it. Unfortunately my warranty already expired, I took my phone to some technicians but honestly it didn't help at all...they all said it was a software bug and I should wait for an update but if it was just that a new ROM would fix it,right?
I am not very familiar with phone hardware but I assume that if it was a hardware problem I wouldn't be able to turn it on or connect to any network, right?? (any experts here???)
Any solution is welcomed.

anyone please?? :crying:
P.S : I tried a new baseband, new kernel and new ROMs. So far, nothing changed.
I can connect sometimes but get kicked out within minutes. At other times I only get the saved,secured message.
This is happening in every network
