[Q] Mobile data not working properly :( - Xperia Z3 Compact Q&A, Help & Troubleshooting

my perfectly working 3g data services arent working properly on the z3c. most often the browser web page will work for a few mins before going off and declaring that wifi and mobile data is switched off .... whatsapp hasnt done that yet... FB has a few times.
Is this a common issue with the z3c, and any solutions? has anyone else faced it too? Help will be appreciated. tia.

also it can be Data problem from Operator and ...
if u have no problem in ur area with other phones so u can fix problem on Z3c by repairing firmware by PC Companion
if problem remains after repairing take it to service center that maybe hardware issue

i had the same problem with sony xperia zr, and some other guys had it too, there is something seriously messed up with sony wifi drivers...
good part is it apears to be a software issue and can be fixed if sony whould give a damn...
http://android.kul.is/2013/09/sony-xperia-zr-wifi-problem.html
here is a detailed post about it, although sony told this guy eventually it was a hardware problem i'm pretty sure it's not, had the same issue on my zr, flashing a new firmware usually fixed it for 3-4 days untill it began again.
i suspected it was some app that i installed that messed up the wifi, anyway i got a new xperia z1 and my zr went to my sister, after a factory reset wifi works fine for her now...... so no idea actually...

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.

Made a factory reset and it's still happening at home and in the office, so it must be the Xperia Z Ultra as other devices work fine in both locations.
How to fix that???
Happen With Me Too
1.136 Indian Branded FTF
To Solve This I Have to Switch Of WiFi and again on it
me using connectify latest version
and when i tried to connect with my bro's lumia connection stays stable
sad sony
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].

same problem in sp i tried to do what u said but wcnss diferent here could tell me how to do that in sp
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 works just perfectly no issues (huawei y9,huawei gr5, galaxy s3), could it be the February update causing the issue
I have just bought the phone and i am very disappointed by the Wi-Fi on this device.
Possible that the February update has caused this. Take backup and reset your phone completely. Check if the problem persists.

Question Sound Lag in Games with WiFi turned on

I've got a Question, I have the Mi 11 Ultra China variant with 8 GB RAM, unlocked bootloader and the official EU Stock Rom.
I noticed that in games even if they are low quality games with low graphics, they are some random Sound Lags.
They appear also with headphones so I suggest this is a Software problem.
I also had that problem with locked bootloader and the official China ROM, so does anyone have or noticed this lag too or I'am the only one?
Edit:
I found the Problem, If I play any games with WiFi turned on, the Sound starts lagging after some seconds , but with mobile data, everthing works perfectly.
Any solutions for that? I tried different WiFi connections and it only happens with WiFi turned on.

I dont think so, every app uses mobile data or WiFi, depending on what if have turned on
This seems for me like a Bad connection, but my Phone is the only device atm and I had never such problems like this in the past with my Phones

Okay so it only happens when you play online? Like with other people on a server? If that's the case i would guess you have a bad internet or wifi connection. So the phone wouldn't be the problem.

Even in Games that have no online play, just Serversided, I got those Lags and in offline games too.
And I know that I have got a very good connection in my country so that wouldn't be the case.
The phone itself is also new so the phone is not the problem, Software I would say
The thing is, my mobile data Connection is worse than my wifi connection.
It is not really the best, just for WhatsApp and so on
I'm out of ideas. I googled a little and other people who had such problems had either bad net latency or something running in the background. I agree that it seems to be some software problem but it's strange that it only happens with active WiFi.
I think it's Software related because my gf got the Mi10 and she has no Problems with WiFi connection turned on.
Let's hope that this will be fixed in the future.
I will Report that to xiaomi.
If someone finds a solutions, they can share them here.
So little Update from me,
Some of my Games that I play had an Update and all of them which had that Sound Problem with WiFi turned on have been fixed.
So NOW I would say it's a third Party App Problem or maybe a Android 11 compatibility Problem with some newer Devices.

Question Mi 11 global Venus sudden restart

I have global Venus mi 11 phone since last security update my phone suddenly shutdown/restart or sometime freeze then auto restart.
Also sometimes force close any app mostly Twitter and YouTube.
Any solution??
Note. Phone not rooted or try not to rooted. And two time factory reseted.
Have this problem too..
Today it restarted for me too...
Happening to me recently too
I had this problem before, and my phone finally bricked 2 months ago.After that, Xiaomi got my bricked mi 11 back, and send me a new phone. You'd better backup the data in case your phone suddenly bricked (or wifi is broken).
Do you have the MIUI 12.5 or 13?
Same here, it happens usualy on mobile internet and while browsing some instagram or fb..
So no one havent find the whats causing the problem or solution to it?
For me it happends only when im on mobile internet for example 4G here in Germany.
It happens usualy when im looking thru Instagram or facebook feed. Its strange and very annoying especialy since I use 4g a lot and need it for travel. Can anyone help? Ive reported it many times but no answers.
To me it happened only once, so all good since then.
msame worries, it was unbearable!! and that since version 15.5.20 Xiaomi.eu
Im still strugling with reboots. It only does on 5G, 4G+, 3G.. I mean on mobile network. On wifi it doesnt happend at all and I think this is problem with lte signals or software. Nothing else.. Has anyone found solution? Im still waiting MIUI 13 for eu version..

No, still happends, everytime when I use mobile internet, on wifi phone rocks, but on 4G it sucks. It happends also to lose mobile network while driving for example when I am in a call and im driving, sometimes phone cant find network but my friend has it.. Its weird problem and I guess there is no solution online.. Will probably destroy this phone because of this, it annoys me a lot.

Are you rooted?? If. Yes please look in folder /root/data/vendor/ramdump.
Are there modem_ramdump files? I have and it was filling up space...
