My phone suddenly won't turn on wifi. It doesn't show any near wifi available and there is no Mac address. I have tried everything, factory reset, clean the cache, repaired through pc companion, and nothing. Phone without wifi is useless. Please help If anyone solved this problem

I have look everywhere but seems like is no solution for it. I'm not sure if flash with custom room would be a way. It might be a hardware problem. I can't sent my to Sony because there is not warranty anymore.

Ok, my warranty expired too! I also tried software repair and still not working and i now see that Bluetooth also is not working.
Hey guys. I fixed this on my phone about a month ago. So far no one has commented if it has helped them or not, but here is my post again. Let me know if it helps.
I had this problem on my Z3c for a while (as well as no wifi or bluetooth). My device is well out of warranty. I received a RMA number last week to send it in in hopes that it would be an affordable fix. I was getting it ready to send out today and decided to try a couple more things.
As others have said, I went in to the diagnostics and test the WiFi (passed) Bluetooth (passed) and GPS (failed). I then decided to test WiFi and Bluetooth a couple more times to see if it would eventually fail. It never did. After that, I went to turn WiFi on manually and to my suprise.... it turned on! Bluetooth and GPS were also magically working.
Before this I had tried numerous factory resets, diferent android versions, different roms (without unlocking the bootloader) with no success. I'm not sure exactly what happened, but hopefully it can work for some of you!

I have exactly the same problem but only one thing is different that my Bluetooth is working. There only problem is wifi. I belive that is no hardware problem. There must be some kind of glitch in software where you accidentally doing this things jumped over. I have tried your tip. No success. Im going to do this every day to see if I have luck. My Bluetooth and wifi passing test every time GPS is failing.

Yes, please do post back your results. I'm not sure if what I did was a fluke of what, but I was shocked when I saw my WiFi turn on. Almost every other post I have seen about this either stops getting replies or the OP sent it in for repair numerous times.

Sorry, I can't help with that. I don't see it on my phone either. I have no idea what that folder is or what it does either.
F*ck, I have same problem, wifi won't turn on. Few times after phone was turned off for long time it worked but mostly just stuck. Bluetooth works so can I be sure it's not a hardware problem?

Hey guys. First of all I want to thank you all for detailed information and in advance for helping me I've got a really weird problem that I can't solve. I bought my milestone from a guy(second hand) and I found wi-fi and bluetooth is not working. I thought that I can solve the problem but I can't find any solution over all android forums.
I flashed some different ROM's but nothing affected the Wi-Fi and Bluetooth problem. When I try to Turn On Wi-Fi it tries to start and then stops then again starts, it goes on and on. I tried to find original MAC address it shows 00:00:00:00:00:00. I tried to Mac Spoof but I can't change it from terminal.
And for the bluetooth I click Turn On then it tries to turn on and stops like I didn't click anything.
As a summary I lost my Wi-Fi and Bluetooth. Anyone can help me restoring it back to normal? Cause in my Area 3G is unstable and I want to use my home network! I can't use it any more. I'm waiting for the good responses.
Thanks in advance...
Please help. This is important for me... If someone helps me I'll donate 15 USD from paypal. Thankssss...
There are several possible reasons why it's not working. They include:
Bad hardware.
Corrupt software.
Non Stock Firmware.
To eliminate the last two, you can flash the appropriate SBF.
To do this, follow the instructions on how to get your milestone back to stock here: http://forum.xda-developers.com/showthread.php?t=696845
On the page to get sbf, scroll down to the 2.1 section and dowload the latest version for your carrier
This will completely wipe your phone, and make it like a new phone. If that doesn't resolve the issue, the problem is probably hardware related.
If this worked for you, please donate the $15 to xda. You can do that via http://forum.xda-developers.com/donations.php
Thanks for quick-reply. But i tried this one before. But it didn't solve this issue. I'll try one more time... How could hardware (both bluetooth and Wi-Fi) be bad? There must be a way to return it back... I'll update this as i try again the original file...

I'd assume that the same chip runs both as is usually the case for embedded systems. If the original firmware doesn't work, the it's likely a hardware issue.
I tried a new update and bluetooth worked for once. And then stopped again. And I sent to warranty they said they cannot change all mainboard cause it'll cost near phone's cost. And after I see Bluetooth works for once I thought may be it's radio based problem. How can I update the original radio update only? Thanks in advance...
I have got exactly the same problem.
I have already sent it back to motorola under warranty and they changed a few things. It work for about a day and then exactly the same.
I thought the update to froyo would work, it did for a day and then reverts back to the same problem.
Have you solved this yet?
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

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

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...
Sent from my C6903 using Tapatalk
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.
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.

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 have upgraded to L using Walter's method. Everything is pretty much good except that I can no longer get a GPS fix in any app I use. I can see plenty of satellites (upwards of 21), but will not get a fix...seemingly ever (I let it try on a 2 hour drive). To clarify, GPS worked quite well on 4.x.
I've tried a few workarounds such as:
GPS settings to get assist data
secret code to rebuild nvm or something like that
turning on and off high accuracy
performed the hardware hack mentioned in the general forum
I haven't tried a factory reset yet, and I'd like to avoid it if possible. Just curious as I've seen this problem detailed for several devices and networks, but no real solutions.
Thanks in advance.

The rooted from post 2. Everything else seems to be good.
Make sure you have oc1 modem. I play ingress and have no GPS issues
There were 2 many reasons why it is very slow to get GPS lock but one problem that I know 100% causes the GPS to lock slowly and not at all because of the aluminium back case that I was using on my galaxy note 3. I tested the GPS status toolbox with back case aluminium and sometimes the GPS lock took long time to fix and sometimes it did not lock at all! But supprisingly, when I remove the back case cover, I don't have that problem anymore. So, check if you have the back case aluminium. Something is interfering with the GPS signal. Now my note 3 is naked without back case but I'm happy this solved the issue. As I said this is one of the problem that caused the GPS lock issue. Perhaps there are more...
Tried everything including factory reset, still no luck
I tried almost everything as OP and did a Factroy reset. Still have the same issue, GPS cant get lock in. It works flawlessly before, start to having this issue after updating to lollipop, dont remember if it happened just after or not.
Is any other possible method to fix this?
Thanks,
As I've already read, SD 835 phones including this one suffer Wi-Fi drops and disconnects. My particular issue is that even though the device is connected to wifi either speed seems to slow down a lot or internet simply doesn't work, I can tap whatever I want in Chrome and the loading bar below the address bar fills in a millisecond and disappears. Happens on different routers, router configuration reset doesn't help nor does device reset. Was the issue already addressed by any update or should I wait?

It is, however most people complain about disconnects making them restart the phone. In my case wifi is still connected, but it sometimes seems to stop working while still being connected and wifi relaunch fixes the issue.. 145 fw didn't solve it, so I guess we should wait.

I returned mine and ordered the US version to see what's what. Should be present there too but one can hope... don't want to give up on the phone but if I encounter it there too then I'll have to go for another model. I'll report back whatever I'll find.
Have a similar wifi problem using (US) firmware .145. A restart fixes it, but eventually the problem resurfaces again. May wait to update until firmware following .179 is available, as I've read that in some cases .179 makes the problem worse. (?)

I did this. Problem was still present on US phone as some predicted. Returned that phone as well.
I'm using CE1 .145 firmware and it started to do that problem a week ago. I have never experienced that before that time. I have to restart my phone at least twice a day and it appears even I'm not connected to any wifi router.
I'll see when update will come. It's horrible.

I'm not experiencing the Wi-Fi disconnect very often, fortunately, but it makes the problem more difficult to diagnose. Odd that some people experience it regularly, even several times a day.

For me it happened several times in a couple of minutes time. I'm on a college campus though, a lot of wifi hotspots around because of the university's wifi network, I think that made it worse.

Several days ago, my xperia also sufering wifi issues. The wifi is disabled by my device.
I have done so much attempts to solve it until I got this:
Connect the device to the PC and open ADB Fastboot. Then, conduct this codes:
adb shell
settings put global captive_portal_detection_enabled 0
That's all. My wifi work again.
I hope that will work on you.
Code:
adb shell
settings put global captive_portal_detection_enabled 0
This worked for me. Thank you
