[Q]Wifi keeps getting disconnected after upgrade to Android 5.0.2 - Xperia Z3 Compact Q&A, Help & Troubleshooting

Both my phone and my wife's phone encountered the same problem.
I therefore do not think it is an individual thing.
It never happened before until we upgraded the system to the latest lollipop.
Any suggestion how to fix this?
Cheers!

Do a reset (obviously), if that doesn't work, run a software repair on Sony PC Companion.

Do the advice, back up your files first. I'm running on stock Lollipop and Wi-Fi is working perfectly.

I had similar problem, my phone had a little problem with authentication and regular disconnecting from wifi. I tried many things like hard reset, software update, router software update etc. even I came back from Marshmallow to Lollipop for a while, but nothing helped me. The solution turned out to be channel in my router. I changed it to 3 after that to 13 - but my phone works only with default channels like 6 or 8. After change my wifi get back to life and now work perfectly. Try it in your case
Channel - This field determines which operating frequency will be used. It is not necessary to change the wireless channel unless you notice interference problems with another nearby access point.

Best answer I've got about this issue. My home router is on channel 6 and the Wifi is really stable. The two work routers that I have access are on Channel 3 and 11 T_T

[Q] My IncS completely disconnects, often!

First of all, let me start of what I've tried doing, in order.
New SIM-card, factory reset, unlock + root, custom ICS (VirtousQuattro).
None of the above solved my problem, it still persists! The problem is, the phone disconnects completely from the network (no bars) and I can't manually search for a new provider due "active package transmission" or something like that, it stays disconnected for 1-3 minutes and then reconnects. It happens fairly often, like once for every 5 times I try using the phone. I haven't noticed the problem when being connected to a WiFi, so I'd assume the problem is related to an issue between the phone and the network.
Has anybody else had this problem? Any idea how to solve it?
Have you tried flashing a new Radio? I can't see how that would differ from flashing a custom ROM, but might be worth a shot?

I haven't tried that, I might in a couple of days if nobody has any other solution though.. I've had the problem for a couple of weeks so I'm kind of used to it!

So much for being "unlocked". Also, hey mate
Yes Naforcee, I have exactly the same problem. And it never happens while using wifi as you said.
It started immediately after I updated to Sense 3 / Android 2.3.5 from HTC.
What was the version of Android in your previous Rom? I had issues when I was on Froyo and went to Gingerbread without flashing a new radio.

Don't think it's a physical problem, I have perfect connection and it just dies out for about 2 min until it reconnects, and I can't search for network when it's down due to active packet transfer..
Could try a new SIM card. Might not fix it, but worth a shot - I've seen this posted as a fix for other people.
I used to have this problem on certain radios on the Desire Z, after flashing around a bunch of radios to try all of them. Stuck with one and it went away, so it was software for me.

Try flashing this radio http://forum.xda-developers.com/showthread.php?t=1471861 using the ADB method. If that doesn't help I recommend doing a full wipe and reinstalling the ROM. There are a lot of different custom ROMs for IncS which can be found at http://forum.xda-developers.com/showthread.php?t=1136463
I personally like Niks ROM and Android Revolution HD.
Looks like rom installation issue.
My son's Inc-S having a similar problem to the OP, but more severe. A couple of weeks ago he entered airplane mode with all behaving normally, but since exiting airplane mode at the end of the flight he hasn't been able to register on the network (voice or data). We've tried:
fiddling with all the network settings
change sims (all sims work on my Inc2, none work on his IncS)
cleaning the antenna connections
reboot
factory reset
flashing new ROM (Android Revolution HD 2.3.0)
flashing new radio (3805.10.03.29_M)
So far, no satisfaction. We're still seeing no bars of reception (with an X) in the notification area, and don't have the option to manually or automatically register with any network operator (although several occasionally show up as options under "Search Networks"). We usually get the error message, "Unable to search for network while packet connection is active" when trying to select a network. Funny thing is, mobile network data has been shut off on his phone for the past month so the packet connection is definitely not active (wifi is on). Based on a network signal analyzer app, the phone is receiving the same mobile network signal as mine (-65 to -70 db) when they are side-by-side, so the problem does not appear to be in the antenna. The phone works just fine using wifi but is useless as a phone.
Any ideas about what to try next?

Probably a RIL-Radio communication issue. Recommended radio is the newer 3822.01.08.14_M radio, so maybe you should try that.

Thanks m8, all my nexus devices are having wifi issue with anything above channel 11, really odd bug can cant get 5G working at all so no AC currently.
Such a strange little bug.
I'm having problems connecting to a Channel 11 WiFi that I don't have to its configuration. This happened since the L Developer Preview and is still there after the 5.0 release.
However, it worked perfectly fine on versions 4.4.4 and older!
A bug report is here.

Thanks, I was on the point of rolling back to 4.4.4 as I wasn't able to get wifi to work again, other than from Safe mode.
However it seems to be working now that I've shifted my channel from 13 to 8
I have the same problem here, finally i'm not the only one having this issue. Fixed after changing Wireless Channel number to 11 from 13 and i'm not sure if this is also related with Wifi drain bug.
Has no one tried:
settings put secure wifi_country_code UK
I'm not in the UK so I can't test but...
Has anyone tried the 5ghz channels? I'm testing on my Shield tablet and I can only see channels 36-44, whereas with Kitkat all the channels were accessible. I've started a thread here http://forum.xda-developers.com/shi...less-detection-lollipop-t2945899#post56965354

I'm also facing a problem with wifi on my Nexus 5 (D821) with Android 5.0.
I can't connect to my wifi repeater TP-LINK TL-WA850RE, the device says it's connected but shows that "!" sign.
I don't know if it has something to do with wifi channels, since the repeater works fine on another devices running Android 4.4.4 and Windows, PCs, etc.
Don't know if it's another wifi bug on Lollipop or what.

Nope, you are not the only one, I have the same problem. I actually did a clean install of Lollipop, it was terrible. Battery pretty much drained in about 8 hours with less than an hour of screen on time. I have reinstalled again (this time installed 4.4.4 and then doing an OTA). Lets see how that fares. Overnight, with minimal apps running I got from 97% to about 74% (7 hours) with wifi off, but in battery stats wifi is being shown as on.

Wifi turning off when phone idle or sleeping

I've got an annoying problem with my phone where the Wifi turns off when my phone is idle or asleep. This means my WhatsApp for Web disconnects and also my Moto Connect plays up too.
I've got the same problem at home, work and parents house so can't be an issue with all 3 networks. The keep wifi on during sleep option is set to Always before anyone mentions this to me.
Phone is running Lollipop 5.0 in the UK and is NOT rooted.
I noticed it doesn't happen when the phone is charging though.
Any ideas?
Right I've now tried changing the Sleep setting to Never but get the same problem.
Also tried connecting to the router via WPS but no luck.
Router is a Superhub 2. I've ruled out that it's the Superhub as I have a Samsung Galaxy S4 Mini that is running fine without a single drop out.
Definitely something Moto X related.
I've also tried on both the 2.4GHz and 5GHz bands with same results!
Try looking within the WiFi settings on the phone. Mine has this

Mine is identical to yours other than the fact that I don't have the wifi optimization option.
Right I've just cleared the cache as instructed by Motorola support.
Still have the same problem even after clearing cache.
Ok I can confirm that the issue goes away when in safe mode.
This is starting to piss me off as I don't have any way of checking if it's an app affecting my wifi disconnections!!!
I've finally found and fixed the problem myself!!
I decided to turn my bluetooth on (even though it wasn't connected to any bluetooth devices). This seems to stop the phone from causing the wifi to go to sleep!
It seems like it's a bug in the Moto X Lollipop firmware. How do I report bugs to Motorola??
It's funny how most say it's apps that cause strange behaviour but for me it's been the actual Android firmware each time I've ever had an issue!
I hope it gets fixed soon.

It's a known bug of 5.0, and already fixed for 5.1. Source, at the "Bug fixes section".
Great that you found a workarround.
Cheers!
Manuel.
Hey glad to know it's a well known bug. The work around still doesn't work. It still keeps disconnecting all the time! Driving me mad!! If the 5.1 update doesn't fix it for me, I'll need to try and get a refund and go for something else. Shame as I really like the Moto X but I can't live with an issue as stupid as this!
I'm not sure Motorola are aware of this issue at all. See their comment below from one of their support staff I'm speaking to now:
Santhosh: We have not received any reports regarding Wi-FI issue after the Android Lollipop update but please give me a moment I will provide the solution for this issue.
His solution for the issue was to get me to do a factory reset lol. I already did this when I first got updated to Lollipop!!
Going to try doing another one now to see if it actually makes any difference. Then will install a few apps at a time or something.
I am connected to WiFi just about all of time, and I have never experienced this.
Right I've done a factory reset and started completely afresh with none of my data or apps restored. WiFi has been solid; I've not had a single drop out!
I'm going to install just a couple of apps at a time and keep an eye out if the issue comes back until I find the culprit.
Hi
My phone was perfect (until now) with the WIFI since november 2014 even after I upgraded it to 5.0
But today, it suddenly starts with this problem by itself. so I restored it to factory defaults with no luck, I installed a new firmware, and still has the bug.
So, why it shows up until now by itself without any mod, app or update?
Sorry for my English.
Today I upgraded it to 5.1 and the issue persists
I had to back to stock 4.4.4. and now my wifi has been fixed so far, working good without interruption until now.
I hope this has fix the problem from sourse, and I'll wait a few days to upgrade it again.
EDIT: Has been a month since my downgrade to 4.4.4. and my WIFI still rocks.
Just want to say that I'm having the same issue since the update to 5.1. Wifi is set to be always on during sleep, but I regularly wake up my phone only to find it connected to 4G, and switching to wifi a few seconds after waking up.
I'm on a locked bootloader (unrooted of course). I did a full reset after the update...
I'm sorry to say that I've seen more little glitches since 5.1 than anything I noticed on 5.0.
EDIT: another issue I'm having is the stock mail client not syncing saying that there is no network connection. My exchange account (push) works fine however...
Just to say the issue has started for me too since the update to 5.1.
I've done 2 factory resets but no luck trying to fix this very annoying problem.
Motorola have asked me to send my phone in for repair so I'll try that and see what happens.

WiFi stops working

I noticed that WiFi stops working on my new G4 pretty often. The WiFi icon is on, and the connection is "up", but the data transmission stops working. I see the top arrow blink (is that transmit?) but the bottom arrow doesn't come up anymore. Trying to do anything fails and times out.
To fix, turning the WiFi off and back on makes it all work again.
Anyone else experience this problem? I know @jonathan3579 reports the same issue.
I am connected to 5 Ghz using an Asus RT-N66 running Merlin firmware. I have no issues with any of my other devices.
Using the "Switch to mobile data" option helps a bit by falling back on LTE when the WiFi stops working.

Are you having this issue everywhere you go or just one specific place?
I had not noticed it at work, but I only got on the WiFi yesterday for a little bit. This morning it failed on me, so, that's two for two. Haven't used it in many places.
The hotspot works great though. I tether an iPod Touch in my car automatically whenever I drive and I haven't noticed any issues there.

I'm at work and I have been watching multiples videos and no issue at all.
I just noticed this today happening to me too. =(.
Pretty great phone otherwise! Also connected 5ghz to a RT-AC68U (the T-Mobile cellspot), flashed with an older Merlin firmware.
Had to reboot to get it to behave again.
Me too
I've been having this issue too. I've noticed that I lose data and WiFi calling simultaneously. I thought it was my router because we were having issues with the router dropping phones and laptop, but now with a new router it is only my phone that is having a problem.

Running DNSet has definitely helped with keeping the data flowing, and I appreciate that.
WiFi calling is still dropping. When I look in the settings it says "enabling" and just hangs.
What internet provider do you have I'm assuming Comcast

This issue appears to be due to the 5ghz radio. I am not sure if it is software or hardware, but if you connect to the 2.4ghz band, the issue will go away.
Its most likely a issue with lollipop

Lollipop on the G4 maybe, but I have used a Nexus 6, a Moto X and a Dell Venue 7840, all running Lollipop, without issues. The G4 is the only one that has this issue. I never tested my old G3 on this network with Lollipop, I sold it before the update rolled out.

I switched to 2.4 ghz and WiFi calling appears to be staying connected. My provider is Oceanic Time Warner and my router is T-Mobile cell spot.
Fingers crossed and thanks for all the help.
Did these wifi problems start after root?
Mine were happening before root, I think. I switched to T-Mobile cell spot router right before I rooted because my old router was regularly dropping connections, and I have been paying attention more since I rooted. I am also caring for 11 month old twins, so things are kind of a blur. What I am saying is I might not be the most reliable source. I can say that switching from 5ghz to 2.4ghz seems to have solved my WiFi issue.

Another WI-FI issue

As I've already read, SD 835 phones including this one suffer Wi-Fi drops and disconnects. My particular issue is that even though the device is connected to wifi either speed seems to slow down a lot or internet simply doesn't work, I can tap whatever I want in Chrome and the loading bar below the address bar fills in a millisecond and disappears. Happens on different routers, router configuration reset doesn't help nor does device reset. Was the issue already addressed by any update or should I wait?

It is, however most people complain about disconnects making them restart the phone. In my case wifi is still connected, but it sometimes seems to stop working while still being connected and wifi relaunch fixes the issue.. 145 fw didn't solve it, so I guess we should wait.

Is the US version affected by this?

No idea, but if people stating it's Snapdragon 835 issue are right , US version should also be affected. I'd rather ask an owner though.

As I recall there was a wifi lag problem with the first couple of builds, but I've had no issues with wifi since November. So perhaps it was fixed in a firmware update?

I've updated to .145 a few days ago (branded rom) and wifi connection seems to have improved, no more hangs. It might be different router in use, so I'll confirm when I'm back home so that I test in on the device I've had problems with.

I've been using .145 all this time. I'm still experiencing the issue.

I returned mine and ordered the US version to see what's what. Should be present there too but one can hope... don't want to give up on the phone but if I encounter it there too then I'll have to go for another model. I'll report back whatever I'll find.
Have a similar wifi problem using (US) firmware .145. A restart fixes it, but eventually the problem resurfaces again. May wait to update until firmware following .179 is available, as I've read that in some cases .179 makes the problem worse. (?)

I did this. Problem was still present on US phone as some predicted. Returned that phone as well.
I'm using CE1 .145 firmware and it started to do that problem a week ago. I have never experienced that before that time. I have to restart my phone at least twice a day and it appears even I'm not connected to any wifi router.
I'll see when update will come. It's horrible.

I'm not experiencing the Wi-Fi disconnect very often, fortunately, but it makes the problem more difficult to diagnose. Odd that some people experience it regularly, even several times a day.

For me it happened several times in a couple of minutes time. I'm on a college campus though, a lot of wifi hotspots around because of the university's wifi network, I think that made it worse.
Solving Wifi Issue of Sony Xperia XZ1 SOV36
Opel_Astra said:
As I've already read, SD 835 phones including this one suffer Wi-Fi drops and disconnects. My particular issue is that even though the device is connected to wifi either speed seems to slow down a lot or internet simply doesn't work, I can tap whatever I want in Chrome and the loading bar below the address bar fills in a millisecond and disappears. Happens on different routers, router configuration reset doesn't help nor does device reset. Was the issue already addressed by any update or should I wait?

Several days ago, my xperia also sufering wifi issues. The wifi is disabled by my device.
I have done so much attempts to solve it until I got this:
Connect the device to the PC and open ADB Fastboot. Then, conduct this codes:
adb shell
settings put global captive_portal_detection_enabled 0
That's all. My wifi work again.
I hope that will work on you.
Code:
adb shell
settings put global captive_portal_detection_enabled 0
This worked for me. Thank you
