[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.

I'm having some strange 3g hiccups lately. I'll elaborate.
sometimes while browsing etc the phone will hang on 3g connections (eg does not even resolve DNS). the data connection icon keeps cycling the 3g and H symbols; at each new symbol switch the upload and download arrows seem to 'do something' for some instants then they fail and start the cycle all over again. I don't even seem to find a way to resolve the issue as putting the phone in airplane mode for some time does not help, and neither disabling 3g networks for a couple minutes. I also tried a reboot which did not help. The only working solution seems to be patiently wait till it works again.
I would not swear on this but I think this issue started when I flashed stock 360. I am however 100% sure that this was not happening, say, a couple months ago.
I am not even sure there is a problem with the phone, there might as well be some problems with the carrier.
anyone experienced anything similar?

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.
Sent from my SAMSUNG-SGH-I777 using XDA App
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.
Hello, folks!
I have a rooted I9100 (Android 4.0.3 stock from Vivo, baseband I9100VILP3, kernel 3.0.15-I9100VJLP7-CL371396 [email protected] #3, compilation IML74K.VJLP7, CSC I9100UVILP3).
Sometimes I have problems turning on WiFi, it keeps always turning on and neither become active nor allow me to turn it off again. I then need to reboot phone to fix it (when it reboots, WiFi comes turned on and gets on normally).
Another problem I have with it is that sometimes (average of 4 - 5 times a day) phone loses registration with carrier. It completely loses* signal and shows a "prohibited" icon where signal strength is shown at status bar. (Edit) Sometimes it comes back again in a few seconds and sometimes it stays at that state, making me have to reboot it to fix the problem (turning on and off airplane mode doesn't work; in fact, with registration lost and trying to use airplane mode, it doesn't turn off and only fixes with reboot).
*Actually, it doesn't lose signal (can be seen in "settings - about phone - state" screen uploaded), but only unregisters from carrier.
(Edit: screen/phone language is Brazilian Portuguese)
I've downloaded another modem driver but never had time to test it.
I don't know if both problems can have the same cause, but both of them are very annoying (especially signal loss) and I'd like to make some tries to fix them, so if anyone knows what can I do (even data collection to investigate them), your help is very appreciated.
Thanks
Additional test (ServiceMode)
When I was in the forum to post this thread, I've noticed this other thread and I've decided to use ServiceMode code (*#0011#) to investigate further at the next time my cell lose signal. Unfortunately, it showed absolutely nothing. Literally nothing (just "ServiceMode" caption and no text on the screen below).
I just spent the time to post this because I know that, even if it has shown no information (on screen), maybe it still can be a clue for the cause of the problem.
Thanks
Pls help!
Does anyone have some light to shed on this case?
Please, I do really need to fix it, at least the signal loss problem.
Thanks.
Same Issue in the US on Tmobile
Mine started doing this just a day or two ago. Exact same issue. I can kind of operate on the EDGE network but 4G fails, only WiFi seems to work. T-mobile doesn't seem to have a fix for it.
Changed to MIUI
I've just changed to MIUI (reflashed modem also – now it is ZSLPE instead of previous VILP3).
I still have issues with carrier register loss, but until now it always reconnected after a few seconds. Maybe it is a carrier issue and not a phone one.
I don't turn on WiFi a lot, but all times I've tested it, it worked well.
Another thing I've noticed with this change is that battery temperature while charging used to reach 48°C (118°F) or even 50°C (122°F) while battery level was low (less than 50%), but now it stayed around 35°C (95°F), which is completely acceptable.
Hello,
Recently, I've been losing data connection randomly. Calls/sms work fine, but I have no data connection. I've found that this typically happens when I leave my home wi-fi network, and then I have no data connection. This also happens randomly, data is working normally, then an hour later, I lose data connection. When this happens, the signal bar is still blue, not grey. Usually, after turning airplane mode on and off, it fixes the problem.
Does anyone know why this is happening and is there a fix to this? I've done a nv_rebuild before, and that may be my last resort.
I am rooted, running Dubbsy's 4.2.2 GE ROM. I would post this question on that thread, but I do not meet the minimum post requirement.
Thanks for reading, and let me know what you guys think!
So I recently got the Realme6 8GB + 128GB, and it's a great phone except for this issue where it doesn't work on my Wifi sporadically.
It will be completely fine browsing reddit for example, then just refuse to load anything despite the wifi icon showing full connectivity. Typically turning the wifi on the phone off and on resolves it easily enough, but it's becoming a constant albeit sporadic thing.
It gets back to normal once I restart the phone but then again it goes back again.
I can't even play PUBG with a constant ping anymore. It's always jumping from green to yellow, yellow to green, despite having a 20 mbps data connection.
I have tested my wifi with my other devices and there's no issue with them, so I know it's the phone.
Any advice or anyone know how to fix this?
wifi issue
i also have a problem with the wifi but mine was when the Bluetooth and Wifi is turned on... the wifi can't receive data or the bandwidth(?)/frequency(?) are in conflict.
This issue happened in update which was before B.45 (B.37 is name of that update i think) I thought it will be fixed in B.45 but it still persists and it is very irritating.
Issue resolved in B.47 update
