Data connection randomly lost - Samsung Galaxy Nexus

Hey guys,
If I connect to a WiFi network or I lost reception, sometimes when I come out of thsoe states I have service sans my data connection. The only way to get it back, other than rebooting of course, is to air plane mode on/off.
Has anyone else been experiencing this? It's happened to me on MIUI and the last 2 AOKP builds.

Losing WiFi Connection Intermittently

Here's the deal: my S2 keeps disabling its WiFi connection. I’ll be connected to my router for a while, sometimes for 12+ hours at time, when all the sudden my S2 will lose its WiFi connection and switch to 4G. When I go into my WiFi settings, it will say that my router is “Not in range” and show no other available networks (even though there are dozens in this area).
I can sometimes get my connection back by toggling Airplane mode or “use packet data” on/off. But nothing works %100 percent of the time. I don’t think it’s a router issue either because we had 4 smartphones in this house over Christmas and the only two that lost their WiFi connection were my and my wife’s S2s.
Anyone else encounter this?
(p.s. Phone is stock, by the way.)
If you have the Tmobile my account disable or uninstall it.I made a thread about this awhile back. It has something where it needs to stay connected to 4g or intermittently puts data on and cuts wifi off I used to have this problem before not no more after uninstalling it.
Thanks, sarni. I read your thread a couple days ago (when I was trying to figure out what was going on), but I'm not sure we're having the same issue. My WiFi and 4G icons aren't on at the same time, for instance.
The other problem is that I haven't rooted my phone, so uninstalling T-Mobile's "My Account" app isn't an option.
Yet.
Happening again now.
Phone seems to be stuck in the following loop: scanning for available WiFi networks, seeing them all, locking in on my WiFi network, trying to obtain an IP address, then back to scanning again without a connection.
No toggling of settings broke the loop until I powered on/off.

Network loss

Ok guys, having a real problem here. Often when I am connected to either 3g or wifi my phone will stop picking up signal suddenly. AIt's almost every time and I will have to disconnect from the network manually and reconnect and it will instantly pick up signal again for a while then it'll repeat. When it suddenly stops it doesn't show on the status bar that I have lost any signal. With 3g its kinda just at a stand still not receiving or uploading and with wifi it just stays the same but I'm still not picking up a signal because by web pages won't load neither will other apps that require network load until I manully disconnect and reconnect. Is anyone else having a problem like this? I don't think it was like this when I firs got my phone a month ago. I'm at a loss. Any help is much appreciated. Oh I'm completely stock btw haven't rooted........(yet) lol

It has happened to me a couple times that I have noticed. I will be streaming music and walking and all of a sudden, nothing.
Even a soft reboot does not help. It will require a full reboot generally to solve the issue. I have not been able to identify the issue specifically. I suspect it might be related to LTE testing in my area.
What's the LTE status in your area?
No lte yet but as I stated earlier it happens on wifi too. It'll still show that the signal is connected but my pages want load at all after it happens and when I try to refresh it'll say that the webpage could not load because there is no network. Only until I manually shut off 3g or wifi in the settings and turn it back on will it pick up signal again but only for about 5 minutes. This has happened in various locations on 3g and wifi and will even happen at home wifi.

This has happened to me as well... A lot . Stock.. on various roms.. No lte as well.. But it's in the works

-Galaxy Note II Edition
I've had this problem too. Sprint replaced my phone and it never happened again.
I think reactivating hands free actually fixed my problem...for now anyway. It's not losing network like it was before. All I did was enter on the phone dial pad ##72786# that'll reactivate. Hope this helps

[Q] No network data connection

Hello all,
I got my P6 for a few days and from time to time I had troubles to connect the data network (2G and 3G).
When I switch the data on, it connects to the network for 1/2 seconde and then it disconnects (the H+ symbol stays on though). Switching the data off and on again only repeats the problem.
Restarting the phone allowed me to finally have a stable connection so far but since this morning it doesn't work anymore. Removing the sim didn't help.
I'm on B125.
Anyone encountered this problem and managed to solve it?
Thanks!
I may have solved the problem.
Use tweakker from the play store to get the exact apn details for your carrier (mine is Base Belgium) and put them in the apn settings.
Since that I can connect the data without any issue (except a new bug: switching to "2g only" make the connection bug again, except if the data is switch off before and switch back on after a dozen of seconds). It seems that it is more like a carrier problem but that creates bugs only with Huawei products (source: internet).
It seems that the P6 is a very capricious phone, I love it but I wouldn't recommend it to anyone which is not an engineer!

Trouble reconnecting to network, 4g but no data

So I live in NYC, and often go underground because of subway or go into buildings with thick walls and no reception, and lose 4G/LTE signal on the phone/building.
When i am out in the open again, the phone will reconnect and shows full bar with 4G/LTE, i can make normal calls/text, however, there is 0 internet data connection.... and takes like 15-20minutes for the phone itself to be able to use data again. this can be fixed with turning on airplane mode for like 3 seconds, and then disable it, but since this happens so often because where I live, this is driving me crazy. Does anybody know what kind of problem this is??
I've searched the forum, and heard that is caused by "ISIS" Sim card from Tmo? any help is appreciated.
sorry for the bump/necro... i am still having the problem :< anybody know this issue?

Mobile Data stops working

Hello,
I live in an area (like many of us) there T-mobile service isn't that great. I daily drive through areas with zero service and I have almost no service at my house so we utilize WIFI Calling.
I have been finding for the past few months that when I return to an area of good service (phone showing full bars of 4G or 4G LTE) that I cannot move any cellular data. If I reboot the phone then everything works again for a while. I have tried to toggle into airplane mode and back but this does not help, only a full reboot helps.
Does anyone else get this? Its very annoying to have to reboot the phone when I need to use cellular data. Appreciate some input. Phone is NOT rooted and running the latest available software from T-mobile

It happens all the time for me. I've not been able to figure out why it happens, but I've seen some speculation in other threads where people think it can break when switching between H+, 4G, LTE, etc. Some people have reported that switching to airplane mode and back fixes it, but it doesn't work for me. Only a reboot will fix it for me.
Here is another thread with some discussion on it:
http://forum.xda-developers.com/galaxy-s6-edge/help/mobile-network-data-connection-drops-t3097605
Thanks for the response. I'm not happy to hear it appears to be happening to everyone. I wonder if any of the carriers have reported this to Samsung?
I cleared the cache partition on my phone 2 days ago and I've been good since...that doesn't mean it fixed it but its been a while since I had 2 good days!
THIS HAPPENS TO ME OMG!!! I thought I was going crazy... it happens quite often in NYC where we travel by subway underground... Switching to Airplane mode then back indeed fix it majority of the time, but it doesn't work sometimes...
Also, this happens when i am on Wifi for extended period of time, and then leave WiFi, the phone will show 4G LTE but wont' push any data.
Going into Phone status will show that you have no IP Address...
edit: btw, i've done an exchange with Tmobile, and still happens on the phone, Swapped SIM card as well, doesn't solve the problem. T-Mobile ran diagnosis, and found nothing wrong. I suspect it might be T-Mobile's network configuration...
Also, I can almost 100% reproduce this when I am playing a game that requires periodic connection (like loading acount info), and then playing in the subway while doing data connection between subway station (we have internet at the station, but not in the tunnel) will break my 4G LTE data connection...
