I have a bizarre problem that just started happening, I can't connect to mobile network after using a wifi connection for some time. No matter what I do, the S6 edge won't connect.
I've tried switching mobile connection on and off, restarting the phone, turning the phone off and back on, switching sim cards with another phone (the other phone immediately gets connection), switching airplane mode on/off. I've gone to Samsung and my mobile provider and they have both blamed each other (of course, right?). The most frustrating part is that this happens about 50-75% of the time with my home and office wifi, and almost never with anyone else's wifi (for example trying it in the Samsung store). It will sometimes get a connection 10-15 minutes later, sometimes it takes several hours.
Samsung service has offered to take the phone in to 'review and test' but they need to do a full wipe and it will most likely take several days of testing. Knowing that the problem is almost impossible to replicate outside of my home and office, and the issue goes away by the time a service tech will ever see the phone, and the struggle to back up and restore my apps without root, I'm not sure what to do right now. Temporarily I have turned off wifi and just use mobile connection, but I'll hit my monthly data cap really soon.
This started happening 2 weeks after AOE4, just upgraded to AOE8 and it still happens. My phone is SM-G9250 with Taiwan ROM.
Screenshots attached to show I have good signal strength but not data connection, and the SIM in another phone having a connection (Zenfone 5 with lollipop).

Did you try wiping the cache?
I thought the cache is wiped whenever you do OTA update?
I'll do it manually again right now and see if it helps. Thanks for the tip.

I have the same issue! Very annoying, and miss phone calls all the time or am unable to make them because of this...
Will try the cache wipe
Wiped the system cache from Boot, problem still there.
I also wiped the cache for all apps.
I also tried the phone in safe mode and has the same problem.

So the only work around I can find is to go into settings:
1.) 'Mobile Networks'
2.) 'Network mode'
3.) Switch to 3g/2g (I don't have 4G right now, have to pay extra for it)
4.) go to 'Network operators'
5.) 'Search Networks'
6.) choose my network provider
Now the phone works just like it always did, smoothly switch between wifi and 3G and H/H+
I'm not sure what changed as I have never had 4G since it costs me extra.

I am on a rooted i777 and have been having signal issues pretty much for the two months I've had this phone. I've done some searching to see what the problem may be but have not come across much.
What happens is that when I have a strong cell signal I am able to send messages and make calls but about 60% of the time when I try to load a web page, update an app's content, or open the market (access the internet in general) I am unable to and left with an "unable to connect" message. During these times only the outgoing arrow of the two beneath the H+ is active. In such situations I switch to wifi but I would rather not have to, especially with an unlimited data plan. So my question is why is this happening and what can I do to fix it. I've nearly thrown the POS over this. It is very odd to say the least. It should be noted that I replaced my AT&T sim card a few weeks ago to no avail. Thank you
I've had similar issues. At various times throughout the day, my phone will be completely without signal or with signal but unable to get any data. I also changed the SIM card to no avail. I don't believe it's the phone but either AT&T or the settings.
Is it possible your reception is dropping off at these times? Does your phone switch to EDGE or GPRS?
Try changing your APN with one of the apps in the market. That tripled my speeds and once I get a new APN to stick, I suspect it will fix the loss of a data connection.
If that doesn't work, return it to bone stock and do a warranty exchange.

I had no data connection tonight and almost nothing worked. In the end, I turned Airplane Mode on and off. That returned my data connection.
I think once it loses signal, it only checks every x minutes. Mine would go a while with no signal, but pick it up immediately if I toggled airplane mode, as you found.
I have had my Xperia P for about a week, and I've noticed on multiple occasions that the signal notification fluctuates quite often. It goes from 0 bars to 4 or 5 and back to zero quite a bit.
Also it tends to not receive data via mobile connection unless you go into airplane mode and go back to mobile data.
This is not a "death grip" issue because it will do this on the table even.
Any thoughts?
it gets kind of annoying.
I'm probably stating the obvious, but have you tried a reboot / other phones?
My Xperia also shows some fluctuation in the signal strength, but no different than for instance my old HTC Hero. However, I never have to go into airplane mode or anything to receive data.
Hey,
Im having kind of the same problem with my Xperia S. When I set the data trafic on, the "3g" sign on the very top of the screen pops up, but dissapears after just 1 second and I dont get any internet connection. The phone has done this before, but then the connection comes back after 10 seconds or so, but now its been gone for 2 days. I know I have full coverage where I am, so its not that.
I've tried and turn the phone off and on again but it didn't help. I have also tried turning data off and on again but nothing seems to help. Is anyone having the same issue as me?
Please help!!
Also going via airplane mode
Hi!
Having exactly the same issues as brdl04. Going via airplane mode is needed like twice a week.
Using Xperia P with firmware 6.0.B.1.564, Swedish operator Telenor.
Wondering if this is limited to specific apps/situations, as I mostly (and nearly always) need to activate/deactivate airplane mode when I need Spotify in online mode. Other apps seem to work fine, sometimes.
I hope Sony will release minor updates too. Seems like they are fully focussing on ICS. Looking forward to it.

Something that has been annoying me since the day I bought the tablet (LTE SPG 521)
When the tablet has been idle for a while, the WiFi turns itself off.
So whenever I pick it up without thinking, open chrome to start web browsing, I am connected to internet, and things are fine until I realise that I have been using 3G instead of WiFi.
Most of the time I need to go into shortcut quick access from pulling down top right corner and turn WiFi on.
Sometimes I need to go into WiFi settings and turn it on, even though the quick access shortcut says WiFi is on.
I do have stamina mode on, but have disabled every other power saving feature related to WiFi. In fact it is the same setting on my Z Ultra and Z1 Compact, but needless to say, I do not see this behaviour on my other sony devices.
But somehow on the tablet, WiFi does not auto connect, even in presence of a WiFi router that is set for auto connect.
Even If I was using the particular access point for WiFi connection, lets say I play games for about 30 minutes... the connection is lost and I need to go into WiFi settings to turn it on again (with the small slide to the right toggle switch within WiFi settings to turn on WiFi itself).
Anyone else experiencing this?
I would rather avoid it, since over usage on 3G for me means speed throttling later in the month...
P.S. Yes, I am on latest firmware 17.1.A.2.69
On Advanced WiFi, Keep wifi on during sleep is set to ALWAYS., avoid poor connection is turned OFF, and Wifi optimization is also OFF
Factory reset it? That's probably the first thing they tell you to do if you approach the technicians, if the problem still persist then demand for an exchange if not refund it.
I'd just bought mine today and unfortunately the bottom right corner the glass sticks out and it is pushable. I'm going to exchange it tmr.

Thanks for the idea, but no luck.
In any case each time I upgraded firmware, it should have sorted itself out, but problem still remains...
"Factory reset" is always the first "solution" you get by "technicians". Usually translates to: "Keeps the customer occupied for hours, silencing him."
Regarding the issue: I cannot confirm that, NO WLAN issues with my LTE Z2, it's just "always on", never losing the connection.

Do you have stamina mode ON?
With my other Xperias, the second I turn my screen on, the wifi is off/sleeping, but it launches and connects almost instantaneously. I guess the problem in my tablet is that it is not doing so, requiring me to do it manually...
I thought the FW for the tablet and the phone Z2 was the same? Maybe I should go and look in the forums over there...
I don't have the problem, either.
UPDATE
Problem Solved.
The cause was ad blocker app that I had installed, and it seems to me that whenever I was using certain apps that needed ad-blocking, all this thing would do is turn wifi off (but not 3g/LTE)
How Dumb is that?
Anyways, Wifi now always on even with stamina mode on.
Thanks for all who listened and threw suggestions!
Thanks

Thank you very much for sharing this with us. Too many others just keep silent if they found the reason of their problems.
My mobile data will randomly stop working even while I'm using the phone. Mind you, it also does this on standby. I will be using the browser and my mobile data for the active SIM (I use 2 SIMs) will just stop working and the phone will tell me that there's no network connection. The 3G/H/LTE text will disappear from the status bar, but I will still have signal to make calls. I have to disable and re-enable data to get it to work again. It does this at least a few times a day.
Anyone else having this problem?
/edit: I realize that sometimes signal for that SIM will drop altogether and come back, but mobile data still has to be manually enabled. Not sure if this is a software issue.
Just done a search on XDA and came across your post. My wife has recently being having problems with her OnePlus X in that mobile signal keeps dropping intermittently. At home we have a 3 Home Signal box and the signal will just suddenly go, check my phone and it's fine. Swap SIMS and it'll be exactly the same, but then just randomly kick back in.
WiFi performance doesn't seem great either after doing several speed tests in various rooms in the house.
Have you still got issues or did you ever fix your problems? Appreciate that this is bringing up an old thread.
[Q] [pseudo-solved] Device occasionally loses Internet connection for WiFi & cellular
The Problem:
I recently upgraded to the Motorola Moto X Pure Edition and have got almost everything running smoothly except for one thing - every so often, (between 2 and 8 days) the device will completely lose its Internet connection for no apparent reason, displaying the little exclamation point next to either the WiFi or cellular signal strength indicators. It usually happens after transitioning between WiFi and cellular (leaving home, arriving home, etc.).
Once the device enters this state, no amount of toggling WiFi, data, or flight mode will allow the problem to be resolved. The device will simply refuse to cooperate with any type of Internet connection at all, even though it still has an IP address, as reported by the ifconfig command in the terminal. No addresses, local or otherwise, can be pinged.
Rebooting the device always brings it back. Clearing the cache and dalvik cache seems to make it last a bit longer, but this has yet to be confirmed.
Troubleshooting efforts and device configuration notes:
A web search turned up nothing at all, although two other people in the original thread on the Moto X Pure Edition Q&A forums revealed that I'm not the only one with the problem. My device is running the stock, Android M Rom, (rooted) but others have reported the same issue with a non-Motorola Android N ROM as well as on the stock un-rooted Rom.
This leads me to believe that the issue isn't Rom-specific, and may not even be device specific. With all this in mind, does anybody have any good tips for troubleshooting this? Any ideas for what could be causing it or how to fix it?
Thanks!
TL;DR? Device loses all Internet connectivity on all connections, usually after transitioning between Cellular & WiFi, on stock-rooted Rom, problem reported on stock and non-Motorola Roms as well. Software or settings conflict suspected.
Update: Hard reset; problem solved. No cause was ever uncovered. See post 7 for all the details.
Internet loss breakage Logcat
Here's the Logcat, if that helps. I tried getting a complete one, but had to cut it off after close to 45 minutes, so there still should be plenty there to go off of.
Any ideas?
Anybody? Any ideas at all? I'll even accept shots in the dark at this point. Made it a record-breaking <9 days, but the problem came back again, even with "Cellular data always active" switched off.
anything? anyone?
Ran into the issue again today, even having left WiFi manually turned off. Any ideas on this? I'll even take shots in the dark. Anything short of hard resetting and reinstalling apps & reinstating settings one-by-one.
Internet dropped out again...
Had the issue again today, but this time caught it "as-it-happens" (as I have only once before). This time, I woke the phone up and saw the exclamation point over the WiFi signal strength indicator, but was still able to use the LTE data connection. Resetting the cellular radio put a stop to that as well.
Any ideas at all? I'm taking complete and total shots in the dark at this point too.
Still losing Internet connection on WiFi, then cellular as well
Same deal again today. Any ideas at all? Anything I can do short of pulling the plug and hard resetting?
Hard reset; fixed
Well, I ultimately pulled the trigger and hard reset the device. The problem appears to have permanently vanished, but we will unfortunately never know its cause.
