Hello. I have a certain problem which I would like to discuss here and ask for advice. I would really like if you could read everything and not just start with the "standard wifi fix" answers like "restart the phone" and such.
1. My problem: The problem that I face is that when I try to connect to a wifi network one out of the two following things happen:
-It connects and instantly disconnects
-It connects and after some time losses connection and says that it's out of range. This can happen after 5 seconds or 15 minutes/it's totally random.
I think that the first thing is connected to the second so let's just discuss the second.
2. Where and when: It happens everywhere and always. It happens at my home, at my school, even in Greece where I spend my vacations (just giving you some examples.).
3. Things I tried to fix my problem myself: I googled my problem for over 1 month now and found a lot of those "standard wifi fixes" I mentioned before. I checked all the settings on my phone for example avoid bad connections, disable wifi during sleep, battery saving etc. I did a factory reset 3 times, I even screwed with my router (even though it can't be my routers fault as it happens everywhere as stated and I am fairly educated in networking and setting up a router). And yes, I did update my phone to the latest version of android available which is 4.1 for me.
4. Contacting my operator: I contacted my operator and gave them a brief overview of my problem. So I went to the store and they sent it to the repair center/company that fixes Sony phones in my country (note: my phone is still under guarantee). After 2 weeks I got my phone back but they wrote that they didn't find the problem and just did a factory reset. After 1 day of usage, with the of course not repaired phone, I sent an very detailed email to the repair center explaining my problem and they told me to send it back again which I did. After a couple of days passed the repair center called me and the guy who was supposed to fix my phone told me that he did a factory reset yet again and that he isn't finding any problems with browsing the net with the phone.
5. Some important information: The phone had never been exposed to any water/fall damage in any kind of form, it was neither rooted/flashed or anything like that and there were no applications that could have messed up any files or settings (for example wifi fix apps and such). I am running the latest available firmware (checked with xperia update checker, sus and PC companion) which is 9.1.A.1.141 R1.
6. Some probably not so important information: A friend of mine which I meet quite often has the same phone but has an different operator is running 4.3 and has no problems with the phone what so ever. Also when I went to the center of my operator the guy that helped me tried to connect to the router he was literary 2 m away from and it instantly disconnected him saying "not in range".
7. Don't say those things as I already tried them without success:
-everything connected to wifi/network/battery saving settings on the phone (avoid bad connections, auto IP, Static/DHCP etc.)
-my router settings (channels, security etc.) - every other device works perfectly fine
-SIM card - calling, mobile data and such works fine
-apps - never had "wifi fix", battery saving or any kind of form of apps on the phone that would "improve" it's performance
So I am really desperate right now and would really appreciate if someone could help me.
EDIT: I forgot to mention that after some time after a couple of minutes it shows the network as being available again (but doesn't reconnect) or waits until I restart the phone before it let's me connect to it again.

Did you update OTA?
If I were you I'd flash a different ROM (different FTF) maybe a different version or a different region, and maybe even backup TA partition, unlock, root, and flash a different Stock ROM and/or a custom ROM (CM, Carbon, etc), and see if the problem persists.
If there still is a problem then it definitely is a phone (hardware) problem, especially considering other devices work on the same network you're attempting to connect to.

I updated using PC companion as soon as I got it.
I would love to try flashing it and using either the latest official unbranded rom for my phone or CM/omnirom but I still have one year of warranty left which I don't really want to void. But to be honest if I can't get to fix the phone in the next month or two I'll probably buy a Nexus 5 and flash the hell out of my xperia T.

When flashing a unbranded ftf with Flashtool you dont lose warranty, as far as I know.
If nothing helps with your issue, you could send the phone to Sony two more times and ask for a refund, should the problem persist. :good:

So if I understood you right flashing does not void my warranty because there is no need to root the phone which means as well that there is not need to unlock the bootloader? Side question, is this "global" or can my operator deny warranty because of an unbranded rom on the phone?

Flashing with Flashtool (the one here on xda, not Sony) is like updating via pc companion.
Just keep an ftf of your original operator firmware on your computer, should you need to revert for warranty purposes.
Flashtool leaves no traces on the device.

There isn't any Unbranded - Central Europe so should I just pick the Unbranded -Germany as there is no Unbranded - Slovenia? It doesn't make any difference anyways as far as I understand it.

I've backed up my TA partition, unlocked it, rooted it, changed ROMs, gone back to stock, relocked bootloader, and it's never left any trace of me having altered it, so if you do things properly, I don't see how you would lose the warranty. What they don't know can't hurt them

I'll be sure to try it as soon as I get my phone back from the repair center. If it doesn't fix my problem I'll just buy a Nexus 5 which should pretty much fix all my problems regarding updates too.
Thank you for the advice everyone.
I had the same problem on my Xperia V with firmware 9.1. Now that I switched to 9.2 the problem is even worse!
Sometimes I loose my connection and in the Wi-Fi list I only see 1 or 2 networks, where I normally see at least 10 networks. Then I reboot and everything is back to normal...
Could be a firmware problem. I don't know if it's possible to reload the Wi-Fi firmware without rebooting?
I've just found that when it starts to bug, I only see networks in the 5GHz band. Networks in the 2.4G band are not visible.

My Nexus One is restarting randomly. I have unlocked the bootloader in order to test out different ROMs and have experienced the issue with Cyanogen's Mod, Android 2.1, Android 2.2 and the HTC Sense Rom. It doesn't seem to be limited to a single app, either. I have reset the phone to as close to stock as I can (2.1, no new apps, stock bootloader as well), and I still have these random restarts. I notice it the most when there is a data transfer going on OTA, whether 3G, Edge or WiFi. Could it be a kernal issue or radio issue? I have done my best to troubleshoot via the internet and my limited knowledge, but nothing is working! Please help!
Try reflashing the recovery, wiping the data/cache etc and reflashing both the ROM and the radio. I had this problem too and doing one of these ended up fixing it. Hope this helps!
My phone did the same and it seemed to be a hardware error. I have returned it to HTC and am awaiting a new device. Hopefully it is not the same for you and a reflash will solve it.
I really think this is a bad RAM issue.
I had this happen to my Nexus (ATT). It was prior to flashing froyo. I tried everything, flashing back to stock (including radio), cyan's latest, Paul's (stock) Froyo (with and without radio). Same result. Seemingly random reboots.
I thought initially that it was a software issue - It would not reboot while in fastboot/Amon's Recovery. But having tried every software combination, I've concluded that it MUST be hardware, unless I'm missing something big.
The phone, for the most part, would be fine as long as I DON'T TOUCH IT. It would stay idle for a long period of time (24hrs+), then I would use it Everything from web browsing to downloading apps to making calls, and it would reboot. It's frustrating because it seems that it's rebooting for no reason except that I'm touching it.
Sent in for a replacement, it arrives today. Hopefully it will not suffer this problem.

Please post an update once you get your new phone. I am in exactly the same boat - had the exact same symptoms with the same result - returned the device and awaiting the new phone which should arrive tomorrow or wednesday.
How were the two of you able to send in your phones after unlocking the bootrom, thus invalidating your warranty?

Hate to necro a thread that is starting to get old but I am having the same issue. Will they still send you a new phone if it is indeed bad RAM? How long does it usually take from the time you send it in?
I have the exactly the same phone and have the exact same problem. Problem is I am in Costa Rica and I would have to send it back with my uncle on the 10th, but then I wont get it back for another month. If I just buy another nexus while I get the current one repaired, do you think I will get another one with the same problem? You can still buy an at&t nexus if you are an android developer correct?

It only invalidates your warranty if you damaged your phone by unlocking. This is a problem that came stock with the phone, we only unlocked it to try fix the problem.
is it a confirmed hardware issue? i started getting this symptom and downgraded to 2.1, flashed the Froyo FRF85 and so far its ok. I also had to format SD card.
If HTC/Google has a confirmed hardware issue on their hand...i smell something akin to antennagate albeit with less finger pointing
Hi,
I have just received my Xperia T from Orange today. The problem I'm having is that the phone will reboot if previously it entered standby with wifi enabled.
I've tried enabling/disabling "Keep WiFi on during sleep" option. The result is the same.
It works fine with Orange data-traffic enabled.
My T is running on 4.0.4 with build 7.0.A.3.223 build number and I can't update automatically.
Im thinking of rooting and switching to custom ROM or manually flashing the official Sony JB - in either case i'm loosing my warranty.
I just want to know first if this is a known issue and it's fixable with a new ROM, and my device isn't broken.
Any help is really appreciated, as I'm so dissapointed by Sony only after 10 minutes of using the T.
Thanks.

No, that isn't a known issue, and it never happened to me when I had that version.
Try upgrading to the newest stock rom an if it keeps rebooting take it back to the shop because it is faulty. As Hackberrybold said, if you flash the original Sony rom, warranty is not voided.

At least the first thread was started by someone with an Orange Xperia too, like yourself; (the second one doesn't specify).
I wonder if this bug is caused by whatever customization Orange applies to its devices...
Weird T-Mobile didn't get 223 version, nothing past 195.
But doesn't have this issue, if you go for a replacement, see if ee will give you a T-Mobile allocated one...

Unfortunately there is no T-mobile in Romania.
In the meantime I'm taking the legit way, just installed Sony PCC and it seems it has a firmware update for me. I will try this and hopefully I'll be a happier T owner.
Things like this make me miss my former HTCs.
All's well that ends well, my T just runs 4.1.2 // 9.1.A.0.489 and it seems I'm able to exit standby normally with WiFi enabled.
Thank you guys for the prompt answers.
Sony newbie OUT.

Hello! It also happens to my Xperia T. I don't think is the Orange customization, because I have the original ROM from Telcel (Mexico), (7.0.A.1.303), but it only happens with one WiFi Network, the one from my school. In other WiFi's it has no problems at all... at least not yet. When connected to that specifically Wi Fi it reboots ONLY if I press the Standby/power button or goes to sleep by inactivity. I've used it for about 15 minutes (Web browsing, Whatsapp, downloading docs, etc.) without pressing the standby button and it doesn't reboot at all until I press that button, or goes to standby after no use (Mine is set up to 1 minute).
I've tried turning on/off de Mobile Data, and it doesn't affect it. I'm actually going to flash JB today, so next monday I'll try again that conflictive WiFi on JB (Stock official ROM).
If anyone can tell me how to get more info on that WiFi (To see if it has something that can trigger the bug, or anything in common with another conflictive WiFi's) I'll do that on monday.
Tnx
I have an issue where I lose mobile signal every few minutes. If I use Llama and check the "recent" tab I can see Cell: -1:-1:-1 every 10 mins or so and if I'm using the phone the signal will go to nothing, then within a few seconds go back up. Has anybody else seen this issue? I've done a factory reset and it didn't help. I'm waiting to hear back from Sony support, but they're been pretty useless for me in the past.

I encountered the same problem on my xperia l.
You could try taking the battery out the phone when it is switched on "hard reset" ,then take out the sim card and reboot, then switch off, put sim card back in and reboot, it may take a couple of minutes, it's worked for some, Me included
Another thing You could try is putting Your phone into GSM mode from settings but this means You need to keep changing modes when data roaming

Whilst we appreciate the sentiment please take a look at the forum your posting your advice in. The Xperia Z1 does not have a removable battery and the term 'switched on ''hard reset'' ' makes no sense unless you mean using the red button in place of a battery pull.
Not trying to be rude but its frustrating when your device drops signal and the best advice you get is regarding completely different hardware.
To Chrisduffer: Have you rooted your device/unlocked the bootloader or flashed another ROM? If so perhaps consider an alternative Kernel or a software update via the flashtool if its still using the stock kernel?
same problem. No root / no flash. Stock 4.3. Same issue even before update to 4.3.
Any idea what to do? My signal drops down every day like 5-6 times for about 20-30 seconds with no reason. I'm also not able to connect to 3G (at least phone is not showing 3g sign next to the signal strenght).
Hmm...this is interesting because actually I saw this up and down on mine too but I was able to call and receive calls anyway...so I newer bother if is an issue or not...but I losing the internet connection frequently so what's wrong?
Instresting...mine too...stock 4.2.2 rooted, Lb....but when my signal totally drops I am able to call or text!

Sounds almost like the modem driver is crashing and then restarting. Factory default is what I would try first, unless this is happening in places where you have weak signal or are in an enviroment which would cause weak signal (inside, thick walls, metal, etc.).

Hypothetically.
Had a few issues myself with the same stuff. Try another radio via flash tool. Just deselect everything else and just flash baseband, no wipe. Be careful when flashing stuff.

Yes, alternative radio driver should help, if it's not HW issue.
I will try to give the phone on a warranty check ... hopefully they will be able to tell me what's wrong ..
if not, I'll go your way = flashing different ROM with different radio.

You think you have signal issues?
Almost forgot, I had a phone come in once and it had the same issue, ended up only recognising the sim card every now and again, you could try another sim, or even send it back for repair which is what happened with the phone that was brought to me.

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.
257 worked much better with my sbh52.

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 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
