Wifi, Wifi tethering and Bluetooth is not working - Sony Xperia ZR

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 Now that my warranty is no longer valid.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 :/

How can i make the wifi stable? it drops in and out sometimes.

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

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.
if u have any solution please inform me.thanku

Milestone Wi-fi/3G connects but not send data

Hello there,
As a newcomer, I found out these foruns filled up with great information and guys willing to help, so came here to ask for some help ....I am both excited and dissapointed with my brand new Milestone. Bought the handset about 5 days ago, which came with Android 2.0. Then updated it straight away to version 2.1 via "Motorola Software Update". So far so good ...here´s the problem I am facing :
While connected to wi-fi or 3g(issue is easier to notice due to 3G icon at the task bar, which points out in those small arrows data that is being sent/received) phone stops to receive data out of the blue. All connectios are cut off(it also happens when the handset is locked up). Some basic trouble shooting i did:
- tested all pcs connected to the same wi-fi network. No issues detected for these
- reset wi-fi router configs. Didn´t work
- tried other wi-fi router. Presented same issue
- swapped another carrier chip to test 3g connection. Presented the same issue
- tested my GSM chip on ther phone. Worked properly
- Reset phone to default settings. This time the connection took longer to drop, like 30 minutes, instead of the usual 10 minutes. After the first drop, it´s started behaving the same way again.​
It seems pretty much that there an issue going on here (obvious...hehehe). I am considering the following:
- Might be a software issue. So, right now i am downgrading it back to 2.0 version, check if it works properly and then move to 2.1 hopping to get the issue fixed.
- Use retailer warranty and claim for a new phone =/​
Could you guys help me out ??
Thanks in advance and Best Regards !!!
Guys, after downgrading version to 2.0, phone stills presenting the same issue. I think it´s turning into hardware issue =/....does anyone have a clue about it?
Thanks and Best Regards!!!

bizare wifi behavior

well, my wifi is acting wierd... reception is good and it doesn't disconnect too often, theres just this little anoying thing!
everytime roughly 3-4 days after i flash a new rom my wifi simply refuses to connect to network, and not a specific one, any network at all!
and it stays like this for a couple of hours and then all of a sudden it picks up a a networks and it works fine for a while, untill i happens again...
i've tried restarting and taking out the battery and turning the wifi off for a while, nothing seems to help, he just decides on his own when he is whilling to connect again....
if i flash a brand new rom the problem disapear for a few days but then it comes back... i'm assuming it has to do with some sort of a cache that is filling up with loads of crap and ruining the wifi activity but i tried googling for this and found nothing..
ideas anyone? (btw this happens on all roms: stock, existenz, beanstalker etc...)
its a hardware problem and not so uncommon look here
http://forum.xda-developers.com/showthread.php?t=2531711
if you can take it to a customer support and if you cant sell it and again if you cant, then just get along with no wifi/bluetooth/NFC check all of them you should have problem with them too

to me that sounds like the start of it because mine was the same at the first few days flashing a new rom or something would help alot but then i just found out the only thing that was helping it to get fixed was the heat from the device not the rom, but it doesnt hurt to play around with it a little so go ahead and try some other roms or repairs.
you see good reception for wifi
you try to connect
at the authorizing or connecting you will see only one point of signal and connection would kinda like disappear.
this is how it was for me but at the first days it was random it was connected good and ready, when i would left the phone in stand by after a few minutes it would DC, so i thought its kind of a sleep mode malfunction or something but after a few days almost 1-2 weeks it turned out to be hardware problem like ohers so if you see any symptom like that start looking for service centers.
but i hope it would be a software problem for you, so good luck.
Well, once he connects he stays on for days, no problem there... Just sometikes he refuses to connect... Pressing the nfc button doesnt help...

What Wi-Fi channel is your network on and have you tried 5GHz?
Didn't look into those things, but it happens with all networks except ones without passwords
Sent from my C6903 using Tapatalk
Have you tried deleting wpa_supplicant.conf in data/misc/wifi and reconnecting to the network? (this will delete all saved passwords and settings for known wi-fi networks) also try to disable Auto IP in advanced wi-fi settings
Well the phone is qith my sister now, I got a new z1 so far wifi worka for her, it stoppes for a few hours yestarday but came back, I might try to flash. 310 and see if it works better with it. And the Wapa_sup sounds like a good idea. Btw z1 is also jittering some with wifi, it's a global Sony problem...

temp solution?
Well, it is probably a hardware problem. I have had the same problem, everything looks fine, but you can't connect to any network.
So, searched, reinstalled, etcétera, nothing worked. Untill I read a crazy solution link://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/xperia-zr-wifi-association-rejected/td-p/516275/page/4
and found out that if you put pressure on the back of your pone right at the NFC chip, with a finger or so, the Wifi will come alive again.
Personally I had to hit my pone's back at that exact spot with my finger (for not damaging it with excesive force) a few times, but then suddenly it worked.
So, I am convinced it's a hardware problem. Hope it works for other people too.

[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)

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 disconnects for unknown reasons

My SM-N900A has been working great for a few years now and is running Android 5.0 from an OTA update (maybe a year ago). A few weeks ago I started having trouble with the wifi. Sliding the wifi control to "on" will sometimes work, but more often it can't find any networks. Often rebooting will fix it, and the wifi will connect (showing a strong wifi signal). Sometimes I see it rescanning several times when I don't think it should be scanning. Then after a few minutes or occasionally up to an hour it will disconnect from the wifi entirely and refuse to show any networks as before. Sometimes I have thought that disconnecting the battery is a surer way to restart the wifi than just rebooting, but it is hard to be sure. This happens with my home wifi, as well as with several other wifi networks I have tried. I haven't dropped or damaged my phone, so I'm wondering if this could be a software problem. I have tried rebooting in safe mode, but the problem persists so I don't think this is caused by an errant application. I have also tried swapping in my spare battery, but that didn't change the problem (although neither battery is a genuine Samsung). If I leave wifi off and just stick to the cellular connection, the phone seems to work as it should. Would there be any logic to trying one of the alternate ROMs on this forum to see if this could fix the wifi problem? One reason I haven't tried this already is that the directions I've seen for installing these ROMs seem to be written for people who have done this dozens of times (which I have not). If this is a reasonable tack, is one of these ROMs known for its ease of installation, or perhaps for the quality and detail of its installation instructions? Are there any less drastic things I should be trying first (other than buying a new phone of course)?
Got the same issue. used odine reinstall 5.0 modem/radio and when that did work, i reinstalled 5.0 and 4.4.4 but nothing worked. i think its a hardware failure. time for a new phone.

Xperia 1 ii | Wi-fi MAC address and BT address unavailable/ Wi-fi and Bluetooth not working

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
