Can't turn on WiFi...WiFi permanently disabled - Xperia Z Q&A, Help & Troubleshooting

A couple of weeks ago, I found my Xperia Z unable to turn on wifi and bluetooth, making the phone almost useless. It was under Android 5.1.1, and to latest version.. but I can't say for sure if the OTA update had happened overnight or not.
Like many others, I had Wi-Fi MAC address and Bluetooth address unavailable in Settings/Status.
Both tests in Settings/Diagnostics returned a "Passed" result.
I went to *#*#7378423#*#*:
- in Service info/WLAN MAC addresses, MAC Address 1 was still present (which already made me doubt that it was HW issue)
- in Service tests, the WLAN and Bluetooth tests failed.
In my case, pushing on the Wifi and Bluetooth button had absolutely no effect.
So I started to read forums and posts regarding this issue.
Like others, I tried to repair the phone through Xperia companion (PC). It didn't fix anything and on top of that, I lost all my data. Not a disaster since you can retrieve a lot of things with the google account.
Then I tried a factory reset, for the same result.
Next, I decided to try to downgrade the system, so I unlocked the bootloader and looked for Sony roms to flash.
In most cases, it just failed, yet I managed to downgrade to 4.4 and 5.0.2. Unfortunately, no more result.
So what else to do ....ANY SOULTION ...PLZ

the info in the original helped me a lot to confirm that my xperiaz still knew its wifi mac address, thanks.
In my case a full factory reset from the settings>backup-and-reset option (Andoid 5.02 on xperia z) did the trick. please try that first after backing up your pictures and downloads and other personal files. Also do this with the usb disconnected and allow the booter to scan for wifi networks during boot rather than deferring until later. Finally dont confuse this kind of factory-reboot with a normal power-off reset. I only did this after it was suggested on the sony xperia website - still useful in 2020.

[Q] Milestone X720 problem with network.

I've purchased a Milestone X720 for my wife, but I found the internal WiFi to work erratically at best.
It seems like it has no problem connecting to Google.com webpage (also it can sync mails and contacts), but when trying to access any other webpages (bbc.co.uk, espn.com, etc.) using the browser, it's always timing out. I know it's not a problem with my WiFi / internal network / router /internet connection, because I can navigate just fine using my HTC Desire or home laptops.
It worked for a while yesterday afternoon, then this morning wasn't able to connect to any website.
The wifi connection is using DHCP, and it shows a correct internal IP address and an excellent signal level. I don't think there's much more things I can tweak in the phone configuration, or isn't there?
Maybe it is a defective phone? Did someone experienced something like this? Should I return it and exchange it for a new one?
I'd appreciate any help.
Alex.
Actually, I've been having problems with my wifi. My wifi will stop working on any webpage at seemingly random intervals (I used to think it was when it went into sleep, but it happens when it's not in sleep now also). Eventually after restarting wifi so many times it'll glitch up and I have to restart the phone.
Providing your phone's stock (as in you haven't rooted it or the like) I'd recommend going to your carrier about the problem.
EDIT: I just checked through the posts on this board and some guy was having another problem with his wifi (different from both of ours though), he suggested getting WifiPowerSavingOff off the market, I'll try it and tell you if it fixes my problem. The only problem is it requires root access, I don't even know if it will fix your problem so you're better off sending the phone back (especially since rooting voids your warrenty). One other thing you could try is just a factory reset, it sounds like a software problem so that might work wonders, you might have to reactivate your phone afterwards though.
Well, thank you for your response.
WiFi was working OK when I came back from work, but is not working now.
The phone is unbranded unlocked, so I'll probably have to talk to the seller.
I tried to see if there was an update from Motorola, but every time I go to the System Updates it says that it is unable to connect to the server, so there's probably no available update for this phone yet.

If it's unlocked OTA updates (updating through the settings) are probably disabled, because installing OTA updates will make you lose root (I'm assuming your phone also is rooted if it was unlocked by the seller). do you know what baseband your using right now? Also, have you installed rom manager or anything that can make nandroid backups?
I might be wrong, but I don't think it's rooted, I think it's just the way it's sold, SIM free and unlocked from factory, not by the seller.
Baseband is 3GSMEPU91A_U_91.07.56I
Well if you wanna double check, just look to see if a superuser permissions app is installed (if you don't find one it's not rooted), I never knew they sold them unlocked (although I'm in the US... so I doubt they do here). All I can say is to try a factory reset then, if that doesn't work then talk to the seller. It sounds like more of a software problem since Google works.
In the end it seems there is some kind of incompatibility between the phone and my WiFi router (a Belkin G). Yesterday I managed to borrow another WiFi router (Netgear) and it works flawlessly when connected to this AP.
I will keep testing during the weekend but I'm pretty sure this was the cause.
Thanks Shiny for your help.
Hi. I picked up a milestone via Ebay two days ago and had similar wi-fi issues. After reading a number of forums I discovered that the problem lay with my router - Siemans Gigaset SE587 (Tiscali). The wireless channel or regulatory domain was set to auto channel 1. I think this confuses the phone so with the help of the router manual I disabled auto and reset it to channel 13.
Wi-fi works flawlessly now and it hasn't affected my other devices. The link below might help.

[Q] Phone will connect to open wifi network but not secure ones

Had my phone for a few months now and recently found that it can't connect to my secure network at home.
When I turn wifi on I get the dreaded connect/disconnect message while it constantly tries to connect to my network. If I leave it on then the battery will drain overnight while the phone tries to connect. I have an iphone which connects to the network no problem. As does my laptop etc
To try to fix this I deleted all my new apps, especially the push ones which give me news updates, etc but this has made no difference.
The weird thing is if I turn off my router's security then the phone will connect and works perfectly fine. I've tried using all the different security settings (even WPS) with new passwords etc and everything seems to setup fine on the phone except it just doesn't want to connect (or more accurately stays connected for a microsecond).
If I go back to an open network it connects immediately and stays connected.
I think this is the root cause of the wifi connection problems that many other people are getting. But I'm at a loss to try to understand why it won't pick up a secure network but works fine otherwise.
My phone is using 2.2.1 and has been rooted
Any thoughts?

Root the problem highly unlikely ..
Secure home network test .
Remove security from Router that is no password .
Remove that connection from phone .
Reboot phone let it pick up router and connect .
If it does then delete reset router password and add in phone .
jje
Thanks for suggested fix. I'll give it a go and let you know if it worked.
Root was a bad choice of word..... I meant that while looking for a solution to my wifi problem I noticed many other people complaining that they can't connect to a wifi network for one reason or another and I was thinking that maybe broken security is a common cause of many wifi connection issues.. In my case there was nothing physical at all to suggest that security was an issue, especially since all my other devices work fine on the same network.
Cheers
Hi, tried your suggestion but I still cant connect. The first time I rebooted the phone it knocked out my internet connection! I've setup a static IP address for my PC and the phone was insisting on trying to connect using the same address and creating a conflict. I fixed that so that's not the issue.
This is what I've tried..
I checked to make sure DHCP was enabled in the router, rebooted everything. No luck.
I tried adding an IP Address Reservation for the phone and assigning a dedicated static IP Address. No luck either
I tried connecting the device using WPS. It all went as it should - my router saw the device, added the mac address to the list of devices etc. The phone acknowledged the handshake. But again it still wont connect.
I checked the router log and it says "DHCP IP: (192.168.1.2)] to MAC address B4:07:F9:336:3D, Tuesday, May 24,2011 03:08:48" which I think is what it should say.
OK I've just fixed it!!! Or at least its connected.
All along I've been securing the network with WPA2-PSK. I just changed it to WEP and the phone connected immediately. I hadn't considered WEP because I read that its not that secure and I do all my banking etc through my PC.
I've tried all the other security options and only WEP works with the phone. I suspect its a compatibility problem between the phone and my router (a Netgear WNT834B v2) because both the phone and router work independently but not very well together. There's plenty of posts discussing the Galaxy S connecting to WPA networks so it can do it.
Now, after trying all the other security options. It won't connect again even on WEP. Bummer. It is acting slightly differently in that its trying to acquire an IP address instead of simply not connecting, although it doesn't seem to be able to find one.
I need to try this on a friends network and see if the router or the phone is to blame. I've no idea... but the phone's a bit too touchy for my liking
I had a similar issue, I had to reflash the ROM to get it to work. Backup all your contacts and stuff and then do a full factory resetting. See if that helps, if it doesnt, reflash the ROM. It should work.
Well I've spent the last few days looking into this issue and it's considerably more widespread than I first realised. The problem is that while many people have a wifi connection issue we all seem to have variations on a theme.
As I say in my case the phone will connect and stay connected to an open network but won't touch a secure one. I tried many suggested fixes and nothing's worked so I am now trying a factory reset.
A couple of questions: there appears to be two ways to do this, a factory data reset through the phone menu; and a hard reset using a combination of volume buttons, etc. The hard reset seems to be the deeper of the two.
When you say full factory setting which one did you mean? I am currently data resetting and therefore using the "authorised" Samsung reset
But how long does this process take? My phone has had a black screen and been vibrating every 10 seconds or so for the last hour. It's getting quite hot and there appears to be no end in sight. Has the phone hung or something? If it has how do I get out of this without bricking the phone? It's beginning to concern me because I'll have to do something real soon.
As an aside, in my search for a solution I found something that might help someone people (it didn't work for me). According to the bloke who posted it, the problem for everyone is that the wifi drivers have not been installed properly and if you enter *#*#526#*#* on your keypad it unlocks a service access that reinstalls the wifi driver. I tried it and the phone told me the software was installed successfully but no change.
Waited long enough so pulled the battery out and restarted the phone. I get the startup screen but after that the screen goes black and it vibrates again every ten secs and I can't get in.
Have to try the other reset.....
Things are going from bad to worse..
Have managed to start a full factory reset using the volume, power and home button but it's gone back into the black screen and vibrating every ten seconds.
I know Im going off topic here but Ive now reset the phone, wiped the cache, tried to apply the sd card update (aborted because it can't find the directory) and it always comes back to the black screen and vibrating every ten secs.
Am now trying to reflash the rom. Oden reports that the flash was successful but the phone wont reboot. I tried a couple of times - one with Re-Partion checked and the other unchecked but neither will reboot. What could be causing that? I somehow remember that my firmware was JPH but I could only get hold of JPK. Could that be the cause?
I seem to have solved all the issues at last. Thought it was going to be a bit over my head for a spell.
Once I discovered that the only way I was going to get into my phone was by flashing the rom the first problem I came across was I didn't know which firmware my phone was using previously, apart from the fact it was 2.2.1 and from Asia. I guessed wrongly and after "successfully" flashing the phone it wouldn't reboot. I then noticed that there were only three variations of the 2.2.1 firmware for my region. The second one I tried went a little further than the first but I got an error message about the SD card. The third one installed no problem.
So I instantly checked the wifi signal and the phone connected to the secured network. And stays connected - so far about an hour and a half.
It's amazing how the phone deteriorated the way it did. Hope it doesn't do it again.
Thanks for any help/suggestions

[Q] Wifi issues on CM 10.1

Hello mates, this is my first time ever posting on the forums, so feel free to call me a newb
So here's my problem. I have been using [JZO54K]_android_4.1.2_v5_oficial_stock_rom on my samsung I9000 for a while and was quite satisfied with how it was working, but I always had a problem with the camera not focusing properly on the moment when a picture is taken. So I decided it's maybe time to try out CM 10.1 (i usually stay away from CMs because i had problems with it freezing or being slow or rebooting without me doing anything on it) hoping it would be a good and smooth experience. So I followed the thread and the instructions precisely (it's not my first time flashing a rom, by any stretch of the imagination). Everything went well, signed in with my google account, google play started restoring my account to the phone, installing the apps and so on and suddenly it stopped. The wifi icon turned from blue to gray, which i know means that it's not getting a connection. So i reset my router, connected to the secondary router in my home and still a gray icon. All my computers in the home work fine, so it's not an internet connection problem. My data plan is out of mb's, so that's noot gonna be an option for me.
So, then i tried opening the browser on the phone, keeps trying to connect, doesn't get anywhere. So i decided to go back to my original rom and guess what? I have the same exact problem. So i tried flashing and reflashing both for a few times, got tired of it. Tried factory reset from the phone's menu, tried clearing everything, all caches, dalvik cache, nothing worked. So i'm stuck with a phone with no internet connection over wifi.
If anyone else had this problem, please help. Obvious stuff will not help me, as I know my way around the block, not that new to this. But i have already tried all the stuff you would get on a google search (like checking if sync is on or opening youtube and all that other stuff)
Thanks in advance, in the mean time, i will be flashing the stock rom with odin and gradually upgrade back up to probably elite's rom.
I've also added a screenshot with my baseband and all that info

So i have just flashed 2.3.6 using ODIN, having the same problem. Will connect to wifi, all internet applications can't get a connection. (and yes, i did check the date and time, in case someone was wondering)
So i have managed to figure out and solve the problem. it wasn't actually an issue from the phone. i tethered another device and managed to get a connection with wifi. it was an actual issue with the way my routers are set up. i have a main router that broadcasts a certain DHCP which is connected to another router that just acts as a bridge. the main router broadcasts in an ip range of 192.168.0.100 to 192.168.0.199 and the secodary router (which i connect to using my phone) that acts as a bridge, usually, if it were not configured to act as a bridge, it would broadcast in ip addresses ranging from 192.168.1.1 to 192.168.1.199; both routers broadcast a different SSID, btw. so the main idea is that, any device that would get an internet connection in the house should have an ip address in the format of 192.168.0.xxx, and this is where the interesting part comes in.
after flashing and reflashing a few times, i started looking into the settings for the wifi on the phone and noticed that it was picking up an ip address of 192.168.1.66. the possible explanation would be that the main router might have stopped broadcasting the DHCP to the secondary one, and the secodary one decided to give it an ip address, hence the 192.168.1.66. but this still doesn't explain why even after reflashing the phone a few times, it still kept the same ip address, which is not suppose to happen, and even if i tried to connect directly to the main routers' SSID, it would still give an ip address of 192.168.1.66.
anyway, managed to get it working, finally decided to go back to elite's rom (after benchmarking on CM10.1, i noticed i get lower scores than what i would get on elite's). and i wasn't suppose to hard reset the phone, i was suppose to hard reset the routers, change the SSIDs on both which is easier and faster to do that anything on a phone.
I don't think that this would apply to anyone else, i guess it was just a freak accident in my home, but hey, if you ever get problems like the one i had, you might want to look into your routers as well

[Q] Need Help, Connection Problem.

I have some problems with my Xperia Sp recently.
At the beginning, my phone failed to load the news-feed (in facebook app) and then I can't play any video posted on that app. The other apps still works well. Several weeks later, I noticed that when I started to browse (in chrome), Google frequently ask me to enter captcha. The next week it getting worse, when I try to search via google image, it never load completely. It look like the pict in attachment_1. Next, the other problem comes, I can't install or update apps from play store. It says "downloading" but no progress (attachment_2). Now, I can't access youtube at all and "some" sites that contain videos. It doesn't even load. I've restored my phone to factory default setting but nothing change.
I try to connect to a WiFi network and suddenly everything works well. So I thought the problem is with my network. Then I try to set my phone as portable WiFi hotspot and tell my friends to connect. All above problems come back again to my phone but everybody who connect to my WiFi hotspot can surf the internet very well.
Please tell me what I should do.....

Ok, I'm not sure, but I have an idea.
You got a Windows PC an the default Sony Android?
Go to PC Companion and search for the option "repair phone".
Then, Companion will download the rom from Sony servers and install it newly. This will erase absolutely everything on the phone. After this, any software error in the phone should be gone. Even if you catched a virus. If you catched one, it could survive a factory reset...
Try this before you try anything with flashtool (in case you read about it). Let's first try the easy options

Upgrade from XZ2 P to xperia 1 ii wifi passwords

OK so I recently aquired a 1 ii and it was mostly painless doing the transfer of data etc except for my wifi SSD's and passwords which turned out to be almost impossible without root, I tried every sort of transfer I could do but wifi passwords were not copied to the new phone - I have about 80 save wifi connections - I did find a solution but is was less than satisfactory - I do not know why both goole and Sony have made this impossible unless you do it manually, so here is what I had to do
On the XZ2 P I opened up the wifi in settings and discovered something I did not k now about before
When you look at a saved SSID if shows the properties of that connection but what it also shows is the password (only ever seen on rooted phone), the is a share option that when opened shows a VR code and the SSID password is shown below it.
So what I did was go through all saved SSID's on the XZ2 P and manually enter them on the xperia 1 ii - yes tedious I know and it took me about 1hr30mins but it was a solution and worked really well - I had an external keyboard connected to the 1 II to make it a lot easier
so I hope this helps anyone that is faced with this issue
regards
in setting > advanced > backup
on old phone, i set it on backup to google account,
when i setting the new phone, it will restore all wifi ssid password.
not only the wifi password, but it also restore photo on my old device to the new one.

I have had google backup enabled on my XZ2P for months - it would not restore ssid's to my new phone, it copied over most of the other stuff, there seems to be some sort of compatability issue between these phones - documents say anything prior to xperia 1 will have issues like this - I tried everything - in fact I spent hours looking and looking for a solution then when I did it took me 1hr30 to do it manually.
If you look at the google backup menu on a recent xperia it does not list the backup contents and certainly not wifi ssid's
This is why I posted this here - I have never come across this problem before - everything always worked
Try to use the sony transfer 2 app.

tried that, like I said above there seems to be functional differences in the devices that prevents direct transfer of data, it specifically mentions from xperia 1 or later, PC Companion is the same
believe me I tried everything
I`ve used it to move from the Xperia X performance.
And also the standard google backup/restore.
Do you install the transfer 2 to your old phone?
