Hey guys/gals -
I got my Moto-X a few weeks ago, and have been using it without issue on AT&T. Unfortunately, I'm just wrapping up my first trip through Europe with this phone (left my iPhone 5 at home), and I've noticed a very odd thing over the last week.
For some reason, my phone will not re-establish a cellular data connection once it has connected to WiFi (and subsequently disconnected from WiFi). I have noticed this - consistently - in both Germany and Italy. In all cases, once WiFi is no longer connected, I can see that the cellular data network is available (the 4G or E logo shows up, grayed out, next to the cell bars) but it will not reestablish. The only way to obtain a cellular data connection is to restart the phone.
I've tried going into airplane mode; I've tried cycling cellular data. Nothing I can think to try causes the cellular network icon ("4G" or "E") to cycle from gray to white...I simply cannot get back online without a full restart. But once I've restarted it works fine - so long as I don't jump on WiFi.
The phone isn't unlocked; it's an AT&T device, with no APN tweaks.
Anyone have any idea what could cause this behavior? Unfortunately, it's going to be another four or five weeks before I'm back here to test any ideas...but I figured I'd reach out while the issue is fresh.
Cheers.
Just to chime in, I've also seen this issue on mine, but it only happens with certain WiFi access points. After using the Cisco ones at work the problem occurs, but my Asus N66U doesn't seem to upset it.
Just upgraded from my M7 to the S6 Edge last Sunday. Since then the S6 has randomly disconnected from both voice and text service twice. The display indicates strong signal and that it's connected but no incoming calls or texts go through. The first time required a reboot to regain connectivity and the second time it took over 5 minutes before it returned. Attempts to make outgoing calls timed out with no connection. Do Not Disturb mode is off and the phone is provisioned correctly. There's no warning that this is happening until someone contacts me using an other method. Any ideas?
I would try a factory data reset. Whenever I've had problems that almost always fixed them. Make sure you back up everything since it totally erases the SD card. If that doesn't work, get a replacement.
I have a complaint out with ATT right now regarding my text messages. Weirdest thing ever - I'm NOT getting text messages at random times from random contacts on my phone but I AM getting them on MightyText, how odd is that? I can't imagine why this is happening, and they've asked me every question in the book all the way down to if my phone had any damage, water or otherwise.... I just got this thing, no it isn't broken!
Hopefully an update or something with figure it out
Try disabling VoLTE option
Has this been happening on your WiFi or mobile data or both? If on WiFi Check with your router it can potentially be dropping packets. Please specify
I have a Microcell and I've unplugged it to see if that was the problem. It was still connecting fine on wi-fi when it did this. I ran a packet loss test and after five minutes there was 0% loss.
Aside from the packet loss did you manage to measure the jitter on the line? Also when connected to the microcell are you surfing through the WiFi or is it using your mobile data still?
It's not jitter either. A 5 minute run all showed times of <1ms . When this occurred the phone had been idled for a few hours and just didn't seem to wake up. It seems to be confined only to voice and text service.
Sounds like your network is fine. Just have to see what att has to say about the smscreen and voice. By the way have you try turning off the volte (enhanced 4g lte) feature as well ?
Well....it just did it again. Definitely not a conflict with the microcell. It seems that once the phone is on and displaying for 3 minutes or so then it will start to work. I've disabled enhanced LTE to see if that makes a difference. It's done this about 48 hours apart now three times. I'm about to dump this thing back on AT&T. I'm beginning to wish I had gone with an M9.
Phone was replaced under warranty. The new one doesn't have this issue at all. Chalk it up to a bad sample.
Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.
No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..
Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835
I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)
I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.
I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.
Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.
Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.
no problem here conecting to 5 and 2.4 wifis...

I haven't gotten around to this yet. Do you still have wifi calling and volte available?

So far my wifi has been fine...
Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.
Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!
exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.
I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Have you turned wifi scanning off ?
settings\Lock screen & security\Location\Scanning - turn wifi scanning off

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.
I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?
My S10 takes a while to find mobile signal after restart or when airplane mode is turned off after turning on. A while here is at least a minute to 2. 60-120 seconds. I don't know this is happening all of a sudden. Happened yesterday while travelling. Also I had installed Cellular - Z and Wifi Man apps before this issue. I used Cellulaz extensively and suddenly now a new issue.
I am sure this was not an issue before. I did a network settings reset, cleaned cache and the mobile signal is really good. Now apps that I mentioned above are uninstalled too.
Anyone faced this issue before ?
Happens only on Roaming
This happens only when roaming and the time taken to find mobile signal is 1 minute . When on non roaming, signal is instantaneously found..within 5 seconds
IDK if it's related (probably not) but I've been noticing my US S10 has lost signal entirely and won't regain it unless the device is rebooted. Happened only twice (so far) but that's still 2 times too many.
I own the Realme 8 (4G) for my wife, and randomly happen that the phone does not receive or make calls (is basically offline) and of course is not in flight mode. After reboot also wi-fi has issue to connect to wi-fi at home on fritzbox router with 2,4 Ghz (it refuse the connection). It's strange if I open the a temporary protected guest mode, it connect without problems (it was using the same channel).
After a while or the morning after it reconnect to the regular access point again. It has occurred almost once every months since we got this phone (4 months actually).
I don't have issues with other devices at home, especially the problem with calls means a problem might be on the phone. I wonder it's a general issue to be fixed with software, otherwise I may call for repair in warranty. Anyone with similar issues?

After 2 years the issue is still there. The phone is updated to last firmware. I'm guessing that it might be related to the connection with certain SIMs.
