[Q] Xperia T disconnects from Wi-Fi automatically. - Sony Xperia T, TL, TX, V

My Xperia T disconnects from Wi-fi automatically. One minute it is connected and running fine but suddenly it disconnects and shows out of range. Strangely this happens only on stock or stock based rom. Wi-Fi runs fine when running CM10.1. So i guess its not hardware issue. I would use CM10.1 but its so unreliable. I missed several important calls due to sudden reboot in CM10.1 and in stock I cant use my Wi-Fi properly. It disconnects automatically. I have tried every wifi setting combination but none of them work. I am frustrated because of this. I have treid every firmware from from ICS to latest .145. But nothing is helping. Is there some kind of wifi power saver that i can disable or maybe i can update wifi driver in my xperia T. I am in desperate need of solution. Please help me. :crying:

Tough one... have you gone into Settings, then Power Management? There is "extended standby mode" option on my phone that seems like it would turn the wifi off while the phone is idling.
Also, is this on any wifi connection? Or mainly your home wifi? It would be worth having a look at the website of your router's manufacturer to see if there is a new firmware available for your wireless router.
I would like to suggest trying stock firmwares from other regions but I don't know how safe that is. Is your phone an LT30a? LT30p?
Right now I'm using LT30p_9.1_A.1.141_PL on my LT30a (Bell) and wifi is quite solid.

yes the extended stand by mode is unchecked. This happens on every wifi. I have been to my friend's home to check for it. It did same there. My phone is LT30p. thank you, I will try other firmwares as well.

wow !! does firmware of TX work on T ??

Yes but not all functions works,camera is upside down ,autobrightness is broken+ some problems with internal storage and other problems....If someone know how to port wifi drivers from TX than it would be great but for now im using Cyanogenmod because on TX firmware was more bugs than on CM....

Wi-fi always on?

hi, i'm new here and didn't found nothing to fix my problem.
I'm trying to use my wifi always on, i already set the wifi-policy on always but it still disconnects when my screen turns off so i'cant get notifications like mail, whatsapp, steam, etc.
i already tried with the different "wi-fi lockers" in the market but nothing.
my previous phone (galaxy 5) didn't have this problem so i think the router it's not the problem.
also, i'm using this baseband "S5830CVJKL4" and obviously in a 5830m (same as c and i)
thanks.

Is your mobile data/roaming turned on ?
Sent from my GT-S5830i using xda app-developers app
Are you using a battery saver (juice defender, for example)? If so, make sure you don't let it control your wifi.
i'm not using battery savers and my mobile data is turned off.
i'll try with a different baseband today, not sure if that have something to do with the wifi.
Weird, i use advanced wifi locker for another tablet that i got that problem and fixes it, though, i noticed that works in some roms and in others don't.
Anyways maybe is because the rom? i use the stock galaxy one and i don't need to use 3rd party to get the wifi on always.
well, aparently IT IS my router, tested in a friend's home with his wifi and didn't have this problem.
weird, the problem it's only when my screen is off, i guess i'll call my internet provider tomorrow, thanks guys.

[Q] Sony Xperia T reboots if on WiFi

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

My problem was most likely HW, because flashing new firmware including the one in the service centre did not work. But it looks like Sony has a lot of problems with the Wi-Fi chips in general - so the range of possible errors is quite broad. If it was a software problem, hopefully new update fixes it.
EDIT: The Xperia article is the most popular article by far on my website - which is sad.
it only happens to me once. the problem was solve once i off the wifi n on it.

Same here. I went into my router config and enable the Packet Flow Accelerator. No issues after that. Seems like Sony wifi chip eats a lot of packet data.

I had the same issue and the wi-fi worked again after I turned on the "Auto IP Support" option in the Wi-Fi advanced menu. Hope this helps.
Might work for other Z series...especially after Custom ROm or updated to 4.3
Hi all just wanna share with you all to all the Xperia ZR users who are facing problem to connect to any 2.4GHz networks. This is an official solution I found after weeks of testing and research. In the end, the driver is not loaded properly or by default, custom ROM created the havoc. So this is a solution finally will end all the Xperia ZR owners WiFi woes:
I noticed that when running ADB GUI, there is this file missing from /System/Data/Misc/WiFi called "WCNSS_qcom_cfg.ini" .
I'm using ADB Helper Version 4.2.0.0, under BUILD.Prop Viewer tab, choose wlan.driver.config it points to that location. I downloaded somewhere from Xperia developer forum website. Then i modified and modified until i found the solution.
in this file modified the line gDotMode=3 (which is running in N mode only) to either 1 or 2 which s "a" or "b" mode.
I reboted the device and the wifi works and N mode is disabled meaning you wont be able to connect in 5GHz mode anymore. But you will be able to connect to all the CURRENT 2.4GHz AP ...yayyy!!! I read somewhere where ICS android allows you to Enable or Disable 5GHz scanning of AP. But later were removed. 4.3 updates sometimes also i found out will WIP this configuration or maybe Developer forgotten to include this as well. I hope Sony Xperia developers will look into this.
Now, my phone can connect to any 2.4GHz WiFi.. I would be willing to help just drop me an email at [email protected].

Re: Somehow it worked for me...
I faced the same Bluetooth & Wi-Fi problem...
For Bluetooth I have got the replacement..
For wi-fi.. I did the tethering..
I created the Hot Spot in another phone and then access that hot-spot from my Xperia ZR..
Luckily it obtained the IP address of Hot-spot and started working
Then without switching off the wi-fi of my phone, I deleted the Hot-Spot connection and tried to access my already created wi-fi router setup fom ZR...
It clicked and started obtaining the IP address of my router..and its working fine from that day...

Yes, I have used it with numerous phones and laptops etc and never had any trouble with it. I am going to try flash a ftf and see if it fixes it.
That didnt help it, I also flashed Miui and it still doesnt work.
If it makes any difference my phones bootloader cannot be unlocked.

No, I bought it second hand, I managed to get it to connect once earlier after removing security but its not working anymore.
Edit: When I have no security on the phones says "obtaining ip address" for about 20 seconds and then seems to reset itself and repeat.

[SOLVED] Wifi issues with Z3c on Marshmallow - possible fix?

Since Sony made the official non-beta Marshmallow available for Z3c many people are complaining about wifi issues: wifi connection is very frequently being dropped. I was searching for possible fixes but none helped.
I wonder if anyone knows how to fix those problems and I also wonder if this issue is only present on some special configurations (rooted/unrooted/RecRoot...). so I am starting this thread in hope to find the solution.
Please help with any useful info you can...

exact same problem with me-i wonder if a factory reset makes any difference?
No issues here at all (UK EE) non rooted
i wonder if this issue is somehow connected with the rooting procedure, since i haven't heard of it on unrooted devices...
I have the same issue with my Z3c and concept rom, rooted. But I don't have the problem since beginning. I got the problems after my move. Now I have disabled visibility of network. In my old flat I had the WiFi visible and never had problems.

Poor Wifi connection on unrooted xperia x3c
toxic-hero said:
I found a fix yesterday, googling!
I have acquired Sony Xperia z3c only recently and upgraded the new device straight to MM, so no experience with previous versions.
I think there may be some improvement using the Lollipop DHCP client, however compare with my other phone Samsung S4 mini (Kitkat) the wifi performance is considerably weaker. Measuring wifi with speedtest.net app I get such different results as 6-8 Mbps with Samsung and 2-3 Mbps with Xperia z3c. At other places where the wifi is even weaker (1-2 Mbps), the S4 mini is still capable of downloading stuff, whereas xperia hardly connects and if so then keeps dropping the connection. I wonder whether the issue is possibly linked to the MM battery optimization, as there is no more the option of not saving battery using wifi. Within the optimized processes I've picked "com-sonymobile-wifi" to not optimize and seems to me that the wifi connection has improved slightly.
Any other suggestions in terms of improving wifi performance through power settings?

I did everyting what mentioned earlier, but nothing helps, I flashed back KitKat, and the issue is still here. It doesn't matter if it's rooted or unrooted. So I flashed back the original firmware and sent back to the local sony service because I still have guarantee for it. Now I'm waiting and maybe they can fix it.
WiFi has been spotty on this phone through all the versions of Android it's had. The legacy DHCP option is new to me I may try out out if i get anymore wifi issues
