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].

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...

I'm using the Sony mw1 Bluetooth with my Z1 and it has been an awesome combination until recently. I'm starting to have substantially more connection problems and the music is now stuttering so much that it's unacceptable (up to 15 second gaps). I also have multiple connection drops throughout the day when I used to literally have none.
Is there anything I can do to diagnose or resolve this potential issue?
My mw1 works fine with my computer so I'm guessing it's the phone somehow.

Did you upgrade recently to 4.3? If yes a factory reset can help.

Ok, you just should know that after an update before do anything you have to make a factory reset to set android well. Sometime, for example, after a fresh installation of Android rom is recommended to reboot your device even 3 times. So sometime when issues appear this can help but no guarantee. Anyway if everything working well should fix it.

I'm starting to wonder if my device is defective. Bluetooth is now acting like wifi, and working when it wants and not at other times. Bluetooth seems to turn off even though its still on (and showing its on). It even persist through restarts but works again if I switch it off then on again. I've already factory reset twice to try and diagnose wifi issues and don't want to for bluetooth issues too. Maybe i'll send it in under warranty.

Believe me it is a firmware issue. This bluetooth issue has been mentioned by several members here after updating to 290. and even after performing factory reset.
This issue has embarrassed me many times at work. It shows "connected" but when I try to answer calls through my sbh52, no voice is coming. and then I try to pick of my phone quickly from my pocket before the caller hangs up.
Flash 257 using flash tool and bluetooth will work perfectly again.
I "upgraded" to KitKat through PC Companion and can't get any sound from the earpiece. I tried the service tests and still nothing. I tried installing KitKat again, this time using an ftf on flashtool and wiping everything; still no earpiece sound. I then flashed another rom (Carbon), and the sound is fine there so it shouldn't be a hardware issue. Does anyone know what the cause could be? Better yet, how can it be fixed?
I gave up on KK for now and just went back to stock 4.2.2 where everything works for me... Would it possibly work right if I update OTA to KK?
I also have the same problem...
Hi guys,
Mine is working correctly after 4.4.2. But I installed it with full wipe and flash pre root, not PCC...

Hi, this is an unsolved bug of the latest stock rom updates. I found a solution:
1. go to Settings --> Apps --> all --> sound enhancements ---> clear data and force stop
2. clear data and force stop Walkman or other music app.
3. restart your cell phone.
But this is not a final solution. The sound bug "comes back" after some days. So, if it appears again you have got to do the same steps.
excuse me if i don't speak english well, I just speak spanish.

I installed SoundAbout. This App told me that my cell phone detects earphones and bluetooth device, but I didn't connect anything.
So, I thought there was a bug in smart connect app, and i was right. I cleared its data. Later, smart connect detected a "phantom" earphones.
It's annoying to make everytime the steps that I posted you, or configuring SoundAbout. I think I'll go back to stock 4.2.2 (the better stock rom for me)

I do not have any problem with this Soundabout really helped me this time
you can use the pro version...
complete all recommendations with bluetooth voice once...!!!!
The steps Claudio provided only seemed to work for a matter of minutes, but now I have been using the phone problem "free" for over 24 hours with SoundAbout installed. So when will we get a REAL fix from Sony? It seems like it should be an easy fix for them since it's just something in the software detecting a phantom headset connected. Should I just forget about that and buy a pro license for this app. Maybe Sony will reimburse me for it, haha
Thank you both for the input!
Well, my SoundAbout trial ended and the problem is back. I'm wondering if there is something in the android script or whatever that would "fix" this before ponying up for the Pro version of SoundAbout. Sucks to have to pay to fix Sony's problem

A friend with an xperia ZR just had this issue also, so i was looking for an alternative to SoundAbout and came across this app.
Thanks for the tip. Right now, I'm frustrated with 4.3 and above, so I went back to 4.2.2. I had another sound problem on KK too; when using my bluetooth headset, if the back of the phone got a little pressure (even from me bending down with the phone in my pants pocket), the bluetooth would disconnect. I would then have to tap or press on the back to get it to reconnect. I was thinking it could be a hardware issue, but I don't have the problem at all on 4.2.2
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 :/

Wifi problem
my sony xperia zr has the same wifi problem it says scanning trys to connect the signal drops and again starts scanning..
I stopped the wifi service and restarted my phone and the wifi worked for a day and again the same proble.
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
Josette
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.
hii.. so did u get any solution for the problem ?
i am facing this problem since one month. i tried rebooting my phone many times. i even tried factory reset. but nothing has worked till know.

Wifi Issue.
Hello Guys,
I have same issue in wifi after 1.5 Year of phone. Can you please help me on that. Does any one knows any other technician are repairing this phone? as SONY says they are not able to repair phone which even they developed. I do n't why such phones developed.
1. I have repaired phone using PCC.
2. tried reset
3. tried without stamina mode
4. tried with wifimanager app
but nothing works....
If you guys any suggestion any hope please let me know.
Thanks.
I just bought a second-hand Xperia 1 ii XQ-AT51 and didn't noticed then that Wi-fi and Bluetooth are not working.
And also that the bootloader is unlocked.
Besides from those issue and that the charging seems to be regular charging, not fast, everything works fine (NFC, Mobile Data, camera, features).
I don't know what the previous owner did, he clearly did something because the bootloader was unlocked; and asking and reading from other post, seems that nobody had these issues when unlocking the bootloader or rooting this model.
I locked the bootloader and tried repairing the software with Xperia Companion. Same software 58.1.A.5.507 (as I see the latest) before and after repair
Guess what: nothing different, although repairing was successful.
Then I unlocked the bootloader, flashed twrp as recovery (probably not necessary in my case) and flashed the stock software with Flashtool, latest from xperifirm (the same version I had before).
But I got some messages that some 3 things didn't flashed (not saved them).
Still the same.
Under Settings -> About it says Unavailable at Wi-fi MAC address and Bluetooth address.
With code *#*#4636#*#* I can see that the Wi-fi MAC address is 02:00:00..... (see attached image).
With code *#*#7378423#*#* at Bluetooth says Enable Bluetooth, at WLAN says enable WLAN, but on another Xperia I can see that it says OK for Enable an then Searching (see attached image).
Do you guys have any idea what to try to solve this issue or what to test in order to find the cause?
Thanks!
hi man ,i have same this issue with my mark II (XQ-AT52) , do you find out the way to turn on wifi and BT ?
Unfortunately no. After an Android/Security update the phone started to restart in about 2 minutes at max. So after 10 seconds or 1 minute it restarted, but not suddenly (like if you disconnect the battery), it was restarting normally. Then I tried software repair, but the phone would be stuck or get out of the flashmode. Enters fastboot but it wasn't seen by PC with adb devices command.
So now I have another issue that most probably will leave my Xperia as a brick. Sadly, because I really liked it.
I have now a SH Galaxy Note 10, but I'm planning to buy another Xperia when this brokes.
I also had the exact same problem as you, so I gave up later, when Android 12 push out and i upgrade but didn't solve problem, so I was wondering whether to continue using it without wifi and bluetooth or send it to Sony for repair.

On mine I also noticed after I bought it that it was opened, so I didn't found if it was hw or sw related, but since you also had this problem probably it is a software issue, or at least not a hardware issue because someone opened it.
Especially if yours is in warranty, I think you should send it to Sony.
If i use a third-party rom like miui , WIFI and BT sometimes can be opened and used, but it will cause the system to crash, so I also think it is a software problem ，maybe related to the persist partition 。
hi guy，I sent my mobile phone to Sony for maintenance. After they tried to update the system again, they told me that I needed to replace the motherboard, which cost $400 , so I gave up and now use the unofficial rom
