unbranded
unbranded MEA

i had the same problem with sony xperia zr, and some other guys had it too, there is something seriously messed up with sony wifi drivers...
good part is it apears to be a software issue and can be fixed if sony whould give a damn...
http://android.kul.is/2013/09/sony-xperia-zr-wifi-problem.html
here is a detailed post about it, although sony told this guy eventually it was a hardware problem i'm pretty sure it's not, had the same issue on my zr, flashing a new firmware usually fixed it for 3-4 days untill it began again.
i suspected it was some app that i installed that messed up the wifi, anyway i got a new xperia z1 and my zr went to my sister, after a factory reset wifi works fine for her now...... so no idea actually...

My problem was most likely HW, because flashing new firmware including the one in the service centre did not work. But it looks like Sony has a lot of problems with the Wi-Fi chips in general - so the range of possible errors is quite broad. If it was a software problem, hopefully new update fixes it.
EDIT: The Xperia article is the most popular article by far on my website - which is sad.

it only happens to me once. the problem was solve once i off the wifi n on it.

Same here. I went into my router config and enable the Packet Flow Accelerator. No issues after that. Seems like Sony wifi chip eats a lot of packet data.

Made a factory reset and it's still happening at home and in the office, so it must be the Xperia Z Ultra as other devices work fine in both locations.
How to fix that???

Happen With Me Too
1.136 Indian Branded FTF
To Solve This I Have to Switch Of WiFi and again on it
me using connectify latest version
and when i tried to connect with my bro's lumia connection stays stable
sad sony

I had the same issue and the wi-fi worked again after I turned on the "Auto IP Support" option in the Wi-Fi advanced menu. Hope this helps.

Might work for other Z series...especially after Custom ROm or updated to 4.3
Hi all just wanna share with you all to all the Xperia ZR users who are facing problem to connect to any 2.4GHz networks. This is an official solution I found after weeks of testing and research. In the end, the driver is not loaded properly or by default, custom ROM created the havoc. So this is a solution finally will end all the Xperia ZR owners WiFi woes:
I noticed that when running ADB GUI, there is this file missing from /System/Data/Misc/WiFi called "WCNSS_qcom_cfg.ini" .
I'm using ADB Helper Version 4.2.0.0, under BUILD.Prop Viewer tab, choose wlan.driver.config it points to that location. I downloaded somewhere from Xperia developer forum website. Then i modified and modified until i found the solution.
in this file modified the line gDotMode=3 (which is running in N mode only) to either 1 or 2 which s "a" or "b" mode.
I reboted the device and the wifi works and N mode is disabled meaning you wont be able to connect in 5GHz mode anymore. But you will be able to connect to all the CURRENT 2.4GHz AP ...yayyy!!! I read somewhere where ICS android allows you to Enable or Disable 5GHz scanning of AP. But later were removed. 4.3 updates sometimes also i found out will WIP this configuration or maybe Developer forgotten to include this as well. I hope Sony Xperia developers will look into this.
Now, my phone can connect to any 2.4GHz WiFi.. I would be willing to help just drop me an email at [email protected].

same problem in sp i tried to do what u said but wcnss diferent here could tell me how to do that in sp

Re: Somehow it worked for me...
I faced the same Bluetooth & Wi-Fi problem...
For Bluetooth I have got the replacement..
For wi-fi.. I did the tethering..
I created the Hot Spot in another phone and then access that hot-spot from my Xperia ZR..
Luckily it obtained the IP address of Hot-spot and started working
Then without switching off the wi-fi of my phone, I deleted the Hot-Spot connection and tried to access my already created wi-fi router setup fom ZR...
It clicked and started obtaining the IP address of my router..and its working fine from that day...

[Q] CM11 WiFi Connection Issue

Hey guys! I have only just joined XDA Developers so please excuse me if I have posted this thread in the wrong area. I have a Samsung Galaxy S Advance (GT-I9070) running stock Jellybean firmware (4.1.2 ITV) but as you all know the stock firmware for this device is full of bugs and freezes often. I successfully rooted my device and installed Team Canjica's CM10.2 ROM (4.3) from the thread on XDA Developers but the WiFi wasn't working. I then installed Maclaw's CM11 ROM (KitKat) because I thought that might solve the issue but it didn't. Here are the details:
Device scans for nearby wireless routers.
I type in the password for my home router.
Device saves router. "Saved, Secured" message displayed.
I tap on my home router in the list to connect.
Device says "Connecting" for a couple of seconds and then goes back to saying "Saved, Secured".
I browsed through the forums and some users suggested switching WiFi Frequency to Auto and turning off WiFi Optimisation but neither of those methods worked for me. The ROM was installed successfully and all other features are working properly so I don't think that is the issue. And my router settings are also alright since I am able to connect to it from my Nexus 7 (2013) properly. Can someone please provide me with a working solution for this issue? I will start receiving very high data usage bills soon because my data plan isn't unlimited. Thank you!

Is your ssid hidden (not broadcasted) by any chance? i had those troubles on hidden home network. Sometimes it worked after a while, sometimes it didn't. What helped me is to broadcast ssid for a moment, get connected with phone, remove broadcast (it will reboot router so phone will lose wifi for a moment). Then somehow it got connected normally
Sent from my SGS Adv. using xda-developers app.

I just checked my router settings and SSID Broadcast is enabled. I tried flashing OmniRom 4.3 thinking that this may be because of a problem with CyanogenMod but the problem still persists. Is there any additional kernel that I was supposed to install perhaps?

CyanogenMod 11 version ?

Just a detail to those who have not upgraded to JB stock and think it is impossible to use it without problems:
All bugs and freezes in Stock JB currently are perfectly finished.
I use STOCK, only with modified kernel (cocore 8.2) without freezes or bugs in months of use.
Enjoy the developer's work (cocafe), because without it JB probably would be impossible in SGA. However we have JB 100% functional and bug-free.
About KK and WIFI bugs:
The only KK (or based) ROM that used without WIFI bugs was RR 20140313.
In fact, the only issue is incall vol. in my experience.
WiFi Direct, Camera -> Panorama is laggy , Screen Recorder not working Not Tested
I also noticed that the battery is worse durability.
But I went back to JB Stock -- personal preference.

Actually I did try that method. Flashed Samsung's latest stock firmware I9070XXLQL (ITV) and then rooted and installed CoCore. To be honest overall performance was much better and UI smoothness was improved. But after a couple of days of regular usage with just a few basic applications such as a note taker, train arrival time, WhatsApp etc. the device started freezing up a couple of times a day again. I admit it worked much better than before but freezes and hangs were still quite frequent. Running OmniROM 4.3 now with no issues so far except for dialer FC, laggy panorama and non functional WiFi hotspot.

This means probably you have typed wrong password. Also check that in keyboard it capitalise first letter automatically. forget the network and connect again

WIFI not working with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.201406
Same wifi problem with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.20140601. Wifi not connecting even after giving the right password (used to work correctly with jb4.1.2 and still works with desktop) only showing saving and connecting wifi. Then the wifi connection is shown to be saved. If wifi does not work with cyanogenmod11, then what's the use of upgrading?
Is wifi is not working in any custom kitkat Rom?
Please suggest a solution.

Try couple times to connect. I remember sometimes I had to reconnect 2-3 times before it gets connection. And the problem with kernel was about WIFI not turning on at all, it was not even search SSIDs.

[Q] [Xperia V] [9.2.A.1.210] Unstable wifi

Hello,
I upgraded my phone to the unbranded/Nordic version (9.2.A.1.210) from the original 9.1.A.1.140.
While this brought many positives (support of BLE for my forerunner & good battery life), it also brought some negatives:
- A terrible clicking noise when the camera is auto-focusing (clearly a known bug in all JB version ...)
- A very unstable wifi
On this second issue, I have not seen any other report of the issue.
The symptoms are quite basic, after some time (around couple of hours), the phone will no longer associate with any wifi.
The only method I found was to enable/disable the airplane mode to restore normal wifi operation ...
I have installed wifi-fixer for having more details, since the wifi is looping on the association mode (could be authentication errors on these known network). Of course, all authentication info are correct as the phone will connect properly once going through the airplane mode ...
I also re-flash that firmware, from the .ftf but also forcing it from Sony SUS ...
At this point I reverted back to 4.1.2 as I'd rather have less features but reliable one (wifi is flawless now - well just as it should be ...)
Anyone else with the problem ? Any solution identified ?

Same problem Here
Would you please point me to the tutorials to get back my phone to 4.1.2, thank you?

Just follow the guide in the general section (i.e. retrieve the right .FTF file and use flashtool), this is very straightforward.

Tried with the ROM from Singapore, same issue ...
=> Association rejected on all known wifi
(using the power button to cycle the airplane mode restore the wifi for 10-15 mn)
Any advice on how to troubleshoot ?

Maybe it's your wifi that gives problem of compatibility when you're on 4.3
Try with another wifi if you can..
And try to change some settings of your current wifi like number of channel, kind of encryption, and so on..

In fact the problem is more complex as sometime my wifi appears to be ok but I do not have any connectivity ...
Now, I believe I found some interesting infos:
=> prb is directly tied with usage of Bluetooth (especially 4.0 BLE)
When the wifi is 'broken', disabling BT will indeed restore normal wifi operation ...
I could not notice the issue before since Android 4.1.2 do not support BLE ...
I've notice others thread reporting WIFI/BT issue (notably around support of smartwatch)
In my case, I'm trying to have my garmin GPS Watch to pair with the phone, this is were the prb can be easily reproduced

I have the same issue! That damned Association Reject!
I can confirm this is due to Sony 4.3 as Wi-Fi still work normally on my other 4.3+ devices (Nexus 7 2012, Galaxy Nexus)
Sent from my LT25i using Tapatalk

Same here
i have tried numerous methods to fix this so far no luck..im on ub flashed 2 3 roms even stock rom with sus

One observation ...
This time, running stock .210 but not installing my BT4.0 Application (Garmin Connect), I only had the Wifi/BT issue once ...
I will install the application but not connect to my watch (Forerunner 620), to see where exactly is the breaking point.
After all these, I will certainly consider unlocking my bootloader and try the Omni ROM (as I see Walter79 is extremely active)

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
. Added photo
Sent from my HTC One using XDA Free mobile app

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, Wifi tethering and Bluetooth is not working

Hi,
I have Xperia ZR C5503 phone about a year. Until 2 months ago I was using Android 4.3. When Lollipop update distributed I upgraded it to 5.0.2.(official)
But sometime after the upgrade my phone started not connecting wifi. It sees the available networks but not connecting them. The signal drops to lowest level about a second while trying to connect and it fails. Also I was using my phone's wifi tethering feature to share my internet to my pc. However wifi tethering is also not working. I enable it but I think it can't work as router. And lastly, I tried to send a file to my phone via bluetooth and it also enables but no other device sees it. I also have low sound on the phone and I can't hear people I am talking to.
So I got frustrated this saturday and downgraded to official 4.4.4. But it was same. Later I unlocked the bootloader and rooted my phone, installed recovery software. With that recovery mode I cleared all caches but the problem still countinued. Lastly I installed an unofficial modified kitkat to my phone but those problems still appears. I don't know why this phone is so problematic for me. I don't know if it is software related or hardware related. Now that my warranty is no longer valid.
Could you give me some ideas to attempt to solve these issues?

Hi,
I had dropped my phone maybe 1 or 2 times but not from high heights.(~ a meter) But that was more than 5 months ago. I am having this issue since last 2 months and I am sure that I didn't drop or harm my phone in any way. However I wash my phone, do you think that could cause that? Just effecting wifi and bluetooth components?

It's not true about dropping the phone make that errors appear, there are many people with same issues, this phone have manufacturing problems, it's not software
My brother have same problem and he never dropped the phone. Just take a look in Sony forums.
Btw, my brother's phone lost Bluetooth connection, NFC, WiFi, Sometimes WiFi works making some pressing in the NFC spot some seconds, but sucks anyway :/

Do anyone has a solution for this??

I have been facing the issue of wifi not connecting, since my upgrade to 5.1.1.
My research has led me to believe that the issue may be software based. However I'm not an expert in the field. And i was thinking of downgrading back to an older version of lollipop when the wifi was not dropping.
Can anyone advise on whether this may be a smart move, or a completely useless one?
Also is there a diagnostic protocol I can go through that could help me figure out for sure whether my wifi is busted physically, as some of you suggest here.
Thanks

I've tried the method "settings global put tether_dun_required 0" but when i reboot my Z5, the value comes back to 1 ... (and of course wifi tethering is not working, going thru USB is ok)

I'm discussing various points here. Check out everyone of this point and get a fair idea from where problem is originating.
1) Go to WiFi Settings > Keep wifi awake during sleep. Here the string value should be "Always"
2) Under stock firmware there are numerous battery optimisation. Some of them kill WiFi so battery can saved. Now disable this features if you want no drops in WiFi.
3) If both of don't work, head over to Xperia ZR General > Search for your specific device FTF. Flash it via flash tool. This should reset all wifi drivers. Don't opt or apply any battery features and use WiFi. If still issue exits then you're in bad luck.
4) Check for other WiFi access points. Check your own router's webpanel and see somewhere broadcasting and multicast signals are ticked. Also check your WiFi is at 100% of it's performance ( 100% transmit power)
5) Hardware issue. Most of the software part is not causing issues so it's safe to say a hardware issue is causing this. Now, long time ago when 5.0 was released for our device I read article regarding ZR. The user had constant WiFi drops. His issue was that his WiFi soldering was poor inside hardware. He soldered it again and his wifi drops were no longer a problem.
People also experience various bluetooth/tethering issue. It's important that people should gain knowledge about firmware flashing techniques so that device would get reset and you yourself could diagnose the problem. 1 in 0.7k unit has software/hardware issue in manufacturing. Sony provides diagnostic app, search in play store ( I'm not sure about this). Hope this answer helps many.
