[Q] Do have the same problem? (wi-fi)

Hello.
I've tryed many ROMs that are here in xda: Froyobread, GingerDX, GingerXperia, kuyaDROID, xGin, etc... And now I am using Stornmix with stock kernel.
But in all this ROMs I've had always the same problem: wi-fi.
My wi-fi connection works good during 1 or 2 minutes. Then it stops working and I can't use the browser nor the market or other app that uses internet connection.
When I turn off and on again the Wi-fi, the internet connection comes back good, but the same happens after few time.
I even tryed 1 wi-fi fix that i've found here, but didn't solve my problem.
Have you guys experienced this problem too?
Any clue how to solve it?

It is already that way.
Always have been.

Delete the remembered connections.Sometimes too much of them cause problems.

There's a compatibility issue with WPA-AES encryption. It's been discussed here and somewhere else (official SE forum i think). Not much to do about it...

Scratch the "AES" and make it "EAP" ...
IF AES would be a problem I think no one of us could connect to their access points as WPA/2 actually uses AES for encryption ...

I had a similar problem with GDX back in the days of v012 onwards. The WiFi connection wouldn't completely die but only go through a disconnect/reconnect loop every 2-5 minutes (unless I used "Wifi Static" to set a static IP configuration for my access point).
I solved the "disconnect/reconnect loop while using DHCP" problem by switching to another WiFi channel (my Access Point automatically determined channel 1 to be the best choice ... I later on switched to channel 11 and the problems fixed itself) - sounds weird, but worked.
You may give it a try.
On the other hand we already had weird WiFi problems which really didn't go away unless one flashed back to stock (where the WiFi suddenly worked flawlessly again) and changed over to the custom ROM again from there.

Thank you for your help, I'll try that and see if it improves my wi-fi.
And yes, as I can remember, it worked nice with the stock rom.

Wi-Fi poblem in JB ROMS

After the wifi fix ( thanks to all devs who worked hard for that ) I am able to connect to my wifi.
But the problem is, I am not able to access my internet. The problem is the same for all JB ROMS(CM 10, miui v5). All I get is short bursts of access to internet during which webpage loads for a bit and just sticks there. Can't access the playstore too. It just gets stuck at signing in.
My wi-fi is good as I am using the same on my laptop.
Can't seem to figure out what the problem is and am sadly stuck on ICS.
Any help would be great...

I don't have this problem ... so its just with your phone try to reflash the ROM

It's just you. Noone else has that problem.

That's what confuses me...How come is it only me having this problem..
I have tried flashing the ROM for 4-5 times now but each time it's the same...
Have tried doing complete wipe, with and without wiping /system, tried both prometheus and NOPE kernels but the problem persists.
And its the same for cm10 and MIUI v5...haven't tried any other JB based ROMS.
Maybe i shall try to turn off security in my wifi..(can that by any chance be causing it??)

Tunring off wifi security can only cause people freeloading on your wifi. I dont know about the problem.

You could turn off password authentication and filter by MAC address, just to be safe and be able to test at the same time. Although, I had no problems on connecting to secure networks. There is an authentication problem on reconnect, though.

Finally solved..
Got my wi-fi to work finally....
The problem apparently was with encryption....got an idea from this HOX thread
http://forum.xda-developers.com/showthread.php?t=1989203
I earlier used to have a AES+TKIP encryption with WPA-PSK authentication....changing network authentication mode to OPEN made it work instantly.
But open connection = freeloaders...so tried a combination of WPA-PSK and TKIP and it worked too...haven't checked it with AES...
Finally wi-fi is working...
Thanks to everyone who tried to help out....i really appreciate it...

Further the wifi now disconnects only if no wifi related task is continuing and the phones locks up.
If a download is going on, it continues even after phone gets locked.
Just thought I should share that...
EDIT: airplane mode trick + wifi keep alive app (kudos to webhijacker for finding it out) does solve the Wi-fi issues..

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].

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...

[Problem] Wi-fi "disconnects" after some minutes

Hi folks,
since I've updated to 4.3 I have this problem on both stock and exisenz ROM. I use location based wifi and when it connects and I lock my phone and leave it there for some time (30 - 40 minutes more or less), wifi stops working. When I unlock my phone, the wifi icon is still there, but in fact wifi doesn't work. If I try to open google play, it says "No connection". To get wifi working again, I have to disable it and re-enable it. This is very annoying because I suddenly stop getting Gmail, Whatsapp, Viber notifications but I cannot know when.
Are you facing the same problem?

Not from what i know of no, I gave up in the end and tried various versions of 4.3 roms and found all of them to be fine with the wifi, but eXistenZ rom gave me problems, so i flashed ultimate pure xsp in the end and had no problems with this rom,

zuk z2 pro wifi problems

Hi there!
I have this zuk z2 pro monts ago and it comes with a custom shop rom. With the custom rom everything worked perfectly except that it doesnt have the option to update its system.
So to be able to update its system, i flashed it with a stock rom and it updated without any problem. Then im starting to notice that when i am on my wifi, some apps seemed to have stopped to connect. So i tried it on data, and it worked fine. Tried to connect it to another wifi of another isp, it works, but when im back on my providers wifi the problem still there. Also tried connecting to other wifi with the same isp as mine, and yeah, still apps dont run.
Now, is it possible that the stock rom is being selective with isps when running wifi? Anyone had this very weird problem like mine?

I have the same problem. When I connect to the wifi from my provider it fails, disconnects, stops working.
But I found a solution (for me): I added an extra wifi-router to my adsl-modem. Now I don't have that problem anymore.
Why this is happening, I don't know.

I think that this happens because Zuk z2 is configured for China region at wifi. You can change the region at custom roms but stock rom doesn't have this option

Other similar problem

In my case I have a similar problem. My Wifi not work in 2.4Ghz frequency only in 5.0Ghz. Somebody can help me? I already flash various custom roms and stocks (using qfil) and basebands (from basebands colections) and one million of possible things. Can would be hardware problem?

Not work! Actually the lineage rom is installed and the region choosed is China. I don't know what I do.

Any solution?

Try to flash 1.9.104 st by qfil . Notice that relock bootloader . If it doesn't improve that means hardware problem .

can be a problem of incompatibility between zuk phone and wifi router as well. Some TPLink routers are already known not to be working good with ZUK Z2 Pro. So it is not always a fault of ZUK

Today i am trying sagemcom modem. No sucess! It connects for only 5 seconds.
After 4 roms(android 7.1 and 8.1), 3 routers(tp-link and Sagemcom) and 2 days, i dont know what to do!
3 months of heavy use and no problems. suddly i heppens!
But if i put the phone on the router(Very close), it keep conected, but the connection is very very very low speed.

Same problem, after stock ROM update wifi see all networks, but impossible to connect. I install zui 1.9, i update, i install persist partition, i try aex, RR... Same problem, wifi can t connect, you have solution?

Any solution?

Solution to my problem.
Sorry, i wasn't to visit here and post the fix i did to solve my problem. Anyways, here it is.
Basically i found out that the problem goes with a sudden incompatibility issue with my phone and the wifi. Im clearly not sure as to what may have caused such, but it come and goes from time to time.
Solution:
I just simply had a reset on my router and walla, solved it. Also, do a clean up on your wifi list. Forget your old SSID, and connect to the new one. This basically solved mine.
Thanks! Keep me posted and see if my solution helps.

I guess you should try the suggestion given at the comment above. But even better than that, you wouldn't have this problem if you had bought my ZUK as you initially wanted to. Cheap is not always really cheap...
