Hi guys, i have a Sony Z2 D6502. I am facing a really weird wifi problem. I can use and connect wifi on 4.4.2 or 314 official, and also cm 12.1 build 5/22 and the previous ones. but when i flash official 5.0.2 build .726 or .28 or newer cm12.1 roms such as build 05/25 or 06/02, my wifi acts crazy. First of all, if it would connect to my router, it can only stay connected for 10-15 seconds max. But most of the times the wifi sections is searching for signals and wifi ssid's constantly show up and then suddenly disappear, and this process of searching continues endlessly. But as i said, sometimes it would connect for 10-15 secs. Also some other times, i will just get a "failed to connect to network" error and it seems the device wouldn't even attempt to connect to the network. i have tried flashing using full wipe, and even flashing existence y patch for d6502 baseband and it didn't help my situation. Come to think of it, I have to say that i have never really been able to use stock 5.0.2 with a normal wifi. When i first tried d6503 lp update with d6502 patch i had the exact issue, and that is the reason why i switched to CM and CM12/12.1 were working normally until the newer releases (05/25 or later ones). If any of you know any solution or any ideas or fixes, i'd really appreciate it.

if you with stock .726 or .28 have issues, then; or you have a faulty d6502, or you have issues with the AP's you are trying to connect maybe.
i would flash .28 and go to a Sony Repair center, im sure its still on warranty.
its hard to me to mentally visualize your issue and fix it, and even so, seems you are the only one reporting that issue ...

Happened to me and It was a faulty motherboard. Sent it to repair under warranty.
I had the same problem
I had the same problem but I got it sorted out.

Well, received my Sony Xperia Z Ultra C6833 a couple of days ago.
Received a notice on the OTA, upgraded to 14.1.B.2.257
I encountered random restart issues whenever Wifi is activated, so I thought, fine.
I finally have access to my computer, installed the PC companion, it prompt me with a new 14.2.A.0.290 update.
Again, I updated my phone, hoping it'll fix the Wifi problem.
After restarting, I did a test, as usual. Wifi problem persists, and what's worse, a new problem. Wifi and Playstation 3 SixAxis controller connected using bluetooth didn't play nice, caused my phone to reboot.
I know a lot of people downgraded the firmware back to the previous version, with NAN backups etc.
And some even managed to restore their IMEI back to normal.
But for my case, I haven't root my phone, attempt to downgrade it using Flashtool, lost my IMEI.
Seems that I have no choice, but to return it back to 14.2.A.0.290 praying that it works, and I still can't see my IMEI.
No, I don't have a NAN backup. That's the part which gave me a headache. I've messed around with HTC one X (a year ago), never had this problem problem before, and it's something new I've learnt from you guys today.
Tried cyangenmod's boot.img, doesn't do me any good.
Anyone managed to recover their IMEI here?
Otherwise I might have to get it back to the dealer for a replacement.
Update: Thanks to krabappel2548's guide, I've managed to flash it to 14.2.A.0.290 again and got my IMEI back, but SixAxis still won't play nice with Wifi, and the problem with random reboots while Wifi is ON still persists.
we have the same issue, mine happened during the old update, after ota wifi gets stuck, wont turn on and reboots the device. upto now its still not fixed. 3 updates have passed and still the issue persist. hope you find a fix it will help me too. tried everything from downgrading, flashing custom rom,kernel, upgrade, unlock, relock but still cant fix it
I guess i'm not the only one then. I can live with the wifi issue for the time being as long as i stick to using data. But i fear it's going to affect tethering should i need that.

Read it the moment I discovered that my IMEI is missing.
I tried reflashing excluding the baseband, doesn't work for me, right after i realized i have a missing IMEI.
Read up on the android emulator, but haven't tried it, as my computer is kinda old, took forever to run it. Will try it once I get my hands on a faster computer
Bah. Crashed when I tried to use my qx100 which i've just received. Haha. Anyone else has any fun with qx100 and z ultra combo? The Z ultra almost reminds me of my ex-girlfriend.
Meanwhile, I can't wait for kit Kat, and hope they really squash these bugs
The best thing would be to contact Sony and make them aware of this bug. Losing your IMEI by simply updating should never happen and it's quite a serious bug.
Actually i lost it after downgrading. Downgrade is simply because of phone keeps rebooting after I turn Wifi on.

I certainly hope so too.
Hope it fixes the rebooting issue with WiFi enabled.
Or the Google Play Edition port if it does fix the problem too
Anyone tested the new update yet? Does it fix the wifi issues with crashing/rebooting?
ok so i purchased my phone on amazon and got it somewhere around feb 25th, i got a message on the phone to update software so naturally i did, then i discovered what rooting does and i decided to follow some youtube instructions to flash my phone to an earlier firmware the link wasnt working so i found another which was C6802_14.1.B.0.475_GENERIC Hong Kong.ftf after flashing this i lost my imei its all zeros and i then tried flashing C6802_14.1.B.1.526_M3dD0g.ftf with no luck so im trying to find out what the updated software was that i must have downloaded when i first got the phone given the date i had recieved it im thinking that the 14.2.A.1.142 is the correct one that i must have updated to, i was running version 4.3 jelly bean before all this happened i also have this problem where everytime i turn off the phone and turn it back on it is in the chinese writing again and asks me to select my language again anyone know what to do short of return the phone while i still got time my internet is extremely slow im tired of it taking 4 hours to load a new ftf just to find out its not the right one ive heard some where hving success with the 290 getting their imei back but im thinking thats the software they started with or updated to to get it back so i have no idea which one i started with or which one i updated to all i know is the date i got it and that possibly its the 14.2.A.1.142 looks really familiar im downloading that one now so we will see what happens and i also read something about flashing excluding the basebands so if that is part of it please make it as clear as possible im obviously a noob but im learning quick
Pleas dont ask the same question in multiple threads.
See my reply to the other thread you necromanced
I just purchased this device using swappa, I actually received the device as of today...I do not have a sim card in it, yes it's rooted...Im currently using a stock JB rom 4.0.4 (have no idea which one)...Here's my problem, it's not connecting to any open SSIDs, I have tried atleast 3 or 4 different ones around my town. Its not connecting, just continues to say saved...I have no tried connecting to any secured SSIDs yet because I dont have wifi at my house. I dont think it's a problem of not having a sim card...Im new to this device and this is the first time Ive ran across this problem. Its not my first android phone, Ive been around for a while...Just trying to get some experienced help from some other users with the same phone. It might also help to tell you that I have shut the phone down and restarted. That did nothing....So has anyone had any kind of problems connecting to any open SSIDs using a stock JB 4.0.4 rom ?

4.0.4 is ICS not jb. You can try flashing the appropriate radio. Since you dont know the history of the device LGNPST is a option, so that you have a fresh start with partitions updated and a working recovery. Here is the link for LGNPST http://forum.xda-developers.com/showthread.php?t=2230994
And here are the radios http://forum.xda-developers.com/showthread.php?t=2270319
If it's on 4.0.4, that's ICS, and if its rooted, it's possible that the JB radio was installed, which could be a problem, because WiFi only works on ICS with the ICS radio, the JB Radio breaks wifi on ICS; also, teh ICS radio breaks wifi on JB.
I'd recommend either flashing a more up-to-date rom, or flash the ICS radio.
Problem was fixed with up to date rom

Hello all,
I encryptet my Z2 phone, after that it takes several minutes to get wifi to work on my phone. Sometimes it get´s connected but drops it right away. After several minutes it managed to keep it and works fine. will work until I reboot the phone again.
Anyone else seen this issue? stock kernel and so on with version: 17.1.1.A.0.402
Been thinking of getting a new firmware and rom, but hard to get everything setup with getting a new rom. Been reading about fastboot and so on, also my win 8.1 won´t find my phone when entering fastboot, seen a issue about that too. Think I atleast have root though
Anyway, this issue is wifi for the moment.
When I was On android 7.0 every thing was working after updating to 7.1.1 wifi and bluetooth stoped working ...
I searched every where but did not find solution
Now again an OTA update came and after updating problem is still there ..
Anyone who had a luck to solve this issue ..
Please Guide me .
Help please

You need a motherboard replacement.
If your phone is still covered by warranty, you can send it to a Motorola repair center to have it fixed (and wait 2 or 3 months).

Then there is no solution.
Mine is still under warranty, I sent it to Motorola two months ago, and they have NOT fixed it yet.
I will NEVER buy another Moto again.
I had this problem with wifi (mac 02:00...) and it came out to be a 100% software problem. I got it as a result of unsuccessful BL unlock, twrp, then root... Finally I decided to get back to locked BL and stock ROM. And "voila!" my wifi is back and is fully functional...
Very Well

Congrants :good:
That is a great new for all of us (if the cause is the same of course).
now the big question, how did you do it?. You could be a little more specific please.
1. what stock frimware you used?
I try whit this (XT1650-03_GRIFFIN_RETAIL_7.1.1_NPLS26.118-20-5-3_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip) this because the build number of my moto z in this moment is NPLS26.118-20-5-3 but i dont sure.
The Frimware i got it from this web https: //mirrors.lolinet.com/ firmware/moto/griffin/official/RETUS/
2. You previous version ROM ( 7.1.1. ) of android corresponse to the new version stock (7.1.1.) you used to flash or are diferents ??.
3. The Build Number Version was equals?
Thanks for your time!!
i got it fixed when i formatted my cell from recovery now wifi is working but bluetooth is not so definitely its not the hardware issue its only related to software
I have a similar problem with wifi (and hotspot) in my Moto Z. Wifi MAC is 02:00:00:00:00:00.
The battery is also drained really quick - it lasts only 1 day.
The problem occurred a few days ago without any good reason - I did not update nor install anything lately. I tried wiping cache - no success.
edit:
MAC has returned to normal, bluetooth is working.
Wifi still does not find any networks.
My battery mod does not charge the phone - I have no idea why

How did you got it back ? Explain something
I did not get it back - wifi still does not work, only MAC returned to normal.
I did not do anything special - just discharged and recharged the phone a few times.
Yesterday I reflashed the kernel (latest TurboZ), wiped cache and power drainage has returned to normal, but MAC is again 02:00:00:00:00:00. No idea why.
Hi everyone,
I have a really annoying issue for a while and I hope someone can have a suggestion.
When i turn hot-spot on, my phone freezes and reboots itself, so i cannot use this feature, however if I connect it to my computer i can share my data by Bluetooth.
More annoying issue, if I try to connect to wi-fi when my data is on, it freezes and reboots again and after that I can connect, but if I disconnect somehow, it reboots again. When I turn the airplane mode on, there is not a problem..
Has anyone of you experienced such issue?
Thanks
Sounds like a corrupt system, probably network driver or baseband
SInce you don't mention anything else I suppose you're on stock ROM , still locked bootloader, no magisk and all that. Simpliest way if your not familiar with ROM and boatloader handling is probably to do a total reset to start with followed by an update. Xperia Companion can be used.
If you're famiiar with ROM handling you may get the latest ROM from XperiFirm which you flash with Newflasher

Hi pergoteborg,
Thank you a lot for your concern.
You are right, I am on stock ROM. I have tried to do a total reset, but it didn't work.
Moreover, I am living in Italy and using Tim Italia, few days ago I was in Austria and in there I did not have any problem when I connected to an Austrian operator. I tried with a different TIM sim card in Italy, it was same. I will try with a different operator as well, but I have not had time yet.
Does it pop up anything on your mind about what could cause such a strange problem?
Thanks in advance.
Regards
