XZ2 (H8296) Wi-fi problem - Sony Xperia XZ2 Questions & Answers

Hello! So I have a very strange (and annoying) wifi problem with my phone. The signal tends to drop even though it is at moderate strength... For example, I currently have a OnePlus 5t and the XZ2. However, when I walk into a room down the hall from where my router is, my OnePlus still receives a stable wifi connection (although at half speed). My XZ2 ALSO receives the same strength of wifi HOWEVER any time i perform a speed test or start a netflix video or watch youtube, the speed of the wifi on the XZ2 gradually but quickly goes down and then the wifi disconnects which leaves me on data. Autonetwork switch is turned off. This problem has become very annoying as I can no longer stream netflix in bed and I don't want to have to return this phone simply because of this very jank wifi issue. The only time I seem to be able to get a stable wifi connection is when I am in the same room as the router. Every other device in my apartment connects to the router just fine. I have tried rebooting the router and rebooting my phone.
I have also tried software repairing the phone to no avail... Maybe this is just a problem with bad hardware?

May you want to reinstall the system with the newflasher including a fullwipe.
Or may you want to use the H8266 firmware?
I use the German H8266 firmware on my h8296 without WiFi problems.

What is the new flasher? I used sony xperia companion. And, I will try to install the h8266 firmware now. Where can I find it?

Use xperifirm from XDA
It will download the firmware for you
The newflasher from XDA will flash it for you
You only need to put the newflasher file into the firmware folder downloaded by xperifirm.
You don't need an unlocked bootloader.
And it will remove your apps, you may want to use Google backup.

I flashed the h8266 usa android 9 firmware and the problem was not fixed... Still same issue. Phone says the connection is pretty good (only one bar missing), then whenever I actually use the internet, speed diminishes and eventually loses connection from the router.
EDIT: it says for some reason the network is "disabled" on my phone

Does it happen with different Wi-Fi's?
Since pi I can't hear Bluetooth audio without stuttering on my old company ThinkPad t440p with Bluetooth 4.0.
While my old ThinkPad t460p with Bluetooth 4.1 is fine.
There wasn't any problems in Oreo.

My router has a 5.0 and 2.4 ghz setting. Both are affected by this issue. The phone doesn't disconnect from other routers I've encountered but its hard to recreate the same circumstances to match the situation of my apartment.
The peculiar thing is that when scanning, the networks still show up. But, for whatever reason, after connecting and using the internet for like, 5 seconds, it would disconnect itself even though the signal is ok (not full but definitely strong enough....). After it disconnects, the network will still show up on the scan and I can reconnect for it to work for 5 more seconds.
EDIT: Also, no other phones are effected by this problem. Not even my roommate's older phone. It is only my XZ2...

Also worth noting that this only happens when there is my bedroom wall in the way. If the phone and the router are in the same room, then everything works perfectly.

I'm in my room too and I don't have any dropping

Very strange... perhaps it could be an app I have installed? However, none of them should affect the wifi...

Quick update. It does appear to only happen with my router... When the wifi signal is weak on other routers, my phone stays connected. However, when it is on my specific router at home, a moderately strong signal is enough for it to drop.

Maybe you want to look into the router settings and only enable the newest 2.4ghz technology.

I just tried that and it didn't work... I'm about ready to give up on this phone to be honest. This is the only device that has this issue in our apartment and we have over 20 devices. It's just weird the phone stays connected until I actually want to use the internet.

Which hardware revision do you own?
Should be on the package.
Did you contact Sony support?
I did it with my Bluetooth pie problem, told them Bluetooth 4.0 is not stable anymore.
How old is your router?
My Fritzbox 7170 and Fritzbox 7490 are working fine.
Did you change the wifi frequency to an unused one?

My router is brand new. It's a tenda ac19. I have not yet contacted Sony support (which is probably what I should have done first) and hardware revision 3

Maybe you just try to disconnect some devices and try your phone first. The router may not handle so many connections like that.

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.

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...

WiFi stops working

I noticed that WiFi stops working on my new G4 pretty often. The WiFi icon is on, and the connection is "up", but the data transmission stops working. I see the top arrow blink (is that transmit?) but the bottom arrow doesn't come up anymore. Trying to do anything fails and times out.
To fix, turning the WiFi off and back on makes it all work again.
Anyone else experience this problem? I know @jonathan3579 reports the same issue.
I am connected to 5 Ghz using an Asus RT-N66 running Merlin firmware. I have no issues with any of my other devices.
Using the "Switch to mobile data" option helps a bit by falling back on LTE when the WiFi stops working.

I'm having the same issue at home. I could be watching a video and suddenly stops. I don't know if it has to do something with root. I noticed it starts happening yesterday. I never had this issue and I got this phone sine 5/27 when it was released. I'll do a factory reset.

I'm not rooted and mine has done it ever since I got it (and did a factory reset before setting it up). I doubt resetting yours will fix your problem.

Are you having this issue everywhere you go or just one specific place?
I had not noticed it at work, but I only got on the WiFi yesterday for a little bit. This morning it failed on me, so, that's two for two. Haven't used it in many places.
The hotspot works great though. I tether an iPod Touch in my car automatically whenever I drive and I haven't noticed any issues there.

I'm at work and I have been watching multiples videos and no issue at all.
I just noticed this today happening to me too. =(.
Pretty great phone otherwise! Also connected 5ghz to a RT-AC68U (the T-Mobile cellspot), flashed with an older Merlin firmware.
Had to reboot to get it to behave again.
Me too
I've been having this issue too. I've noticed that I lose data and WiFi calling simultaneously. I thought it was my router because we were having issues with the router dropping phones and laptop, but now with a new router it is only my phone that is having a problem.

Running DNSet has definitely helped with keeping the data flowing, and I appreciate that.
WiFi calling is still dropping. When I look in the settings it says "enabling" and just hangs.
What internet provider do you have I'm assuming Comcast

This issue appears to be due to the 5ghz radio. I am not sure if it is software or hardware, but if you connect to the 2.4ghz band, the issue will go away.
Its most likely a issue with lollipop

Lollipop on the G4 maybe, but I have used a Nexus 6, a Moto X and a Dell Venue 7840, all running Lollipop, without issues. The G4 is the only one that has this issue. I never tested my old G3 on this network with Lollipop, I sold it before the update rolled out.

I switched to 2.4 ghz and WiFi calling appears to be staying connected. My provider is Oceanic Time Warner and my router is T-Mobile cell spot.
Fingers crossed and thanks for all the help.
Did these wifi problems start after root?
Mine were happening before root, I think. I switched to T-Mobile cell spot router right before I rooted because my old router was regularly dropping connections, and I have been paying attention more since I rooted. I am also caring for 11 month old twins, so things are kind of a blur. What I am saying is I might not be the most reliable source. I can say that switching from 5ghz to 2.4ghz seems to have solved my WiFi issue.

Wifi, Wifi tethering and Bluetooth is not working

Hi,
I have Xperia ZR C5503 phone about a year. Until 2 months ago I was using Android 4.3. When Lollipop update distributed I upgraded it to 5.0.2.(official)
But sometime after the upgrade my phone started not connecting wifi. It sees the available networks but not connecting them. The signal drops to lowest level about a second while trying to connect and it fails. Also I was using my phone's wifi tethering feature to share my internet to my pc. However wifi tethering is also not working. I enable it but I think it can't work as router. And lastly, I tried to send a file to my phone via bluetooth and it also enables but no other device sees it. I also have low sound on the phone and I can't hear people I am talking to.
So I got frustrated this saturday and downgraded to official 4.4.4. But it was same. Later I unlocked the bootloader and rooted my phone, installed recovery software. With that recovery mode I cleared all caches but the problem still countinued. Lastly I installed an unofficial modified kitkat to my phone but those problems still appears. I don't know why this phone is so problematic for me. I don't know if it is software related or hardware related. Now that my warranty is no longer valid.
Could you give me some ideas to attempt to solve these issues?

Hi,
I had dropped my phone maybe 1 or 2 times but not from high heights.(~ a meter) But that was more than 5 months ago. I am having this issue since last 2 months and I am sure that I didn't drop or harm my phone in any way. However I wash my phone, do you think that could cause that? Just effecting wifi and bluetooth components?
It's not true about dropping the phone make that errors appear, there are many people with same issues, this phone have manufacturing problems, it's not software
My brother have same problem and he never dropped the phone. Just take a look in Sony forums.
Btw, my brother's phone lost Bluetooth connection, NFC, WiFi, Sometimes WiFi works making some pressing in the NFC spot some seconds, but sucks anyway :/

How can i make the wifi stable? it drops in and out sometimes.
Wifi problem
my sony xperia zr has the same wifi problem it says scanning trys to connect the signal drops and again starts scanning..
I stopped the wifi service and restarted my phone and the wifi worked for a day and again the same proble.
Do anyone has a solution for this??
I have been facing the issue of wifi not connecting, since my upgrade to 5.1.1.
My research has led me to believe that the issue may be software based. However I'm not an expert in the field. And i was thinking of downgrading back to an older version of lollipop when the wifi was not dropping.
Can anyone advise on whether this may be a smart move, or a completely useless one?
Also is there a diagnostic protocol I can go through that could help me figure out for sure whether my wifi is busted physically, as some of you suggest here.
Thanks
Josette
I've tried the method "settings global put tether_dun_required 0" but when i reboot my Z5, the value comes back to 1 ... (and of course wifi tethering is not working, going thru USB is ok)
I'm discussing various points here. Check out everyone of this point and get a fair idea from where problem is originating.
1) Go to WiFi Settings > Keep wifi awake during sleep. Here the string value should be "Always"
2) Under stock firmware there are numerous battery optimisation. Some of them kill WiFi so battery can saved. Now disable this features if you want no drops in WiFi.
3) If both of don't work, head over to Xperia ZR General > Search for your specific device FTF. Flash it via flash tool. This should reset all wifi drivers. Don't opt or apply any battery features and use WiFi. If still issue exits then you're in bad luck.
4) Check for other WiFi access points. Check your own router's webpanel and see somewhere broadcasting and multicast signals are ticked. Also check your WiFi is at 100% of it's performance ( 100% transmit power)
5) Hardware issue. Most of the software part is not causing issues so it's safe to say a hardware issue is causing this. Now, long time ago when 5.0 was released for our device I read article regarding ZR. The user had constant WiFi drops. His issue was that his WiFi soldering was poor inside hardware. He soldered it again and his wifi drops were no longer a problem.
People also experience various bluetooth/tethering issue. It's important that people should gain knowledge about firmware flashing techniques so that device would get reset and you yourself could diagnose the problem. 1 in 0.7k unit has software/hardware issue in manufacturing. Sony provides diagnostic app, search in play store ( I'm not sure about this). Hope this answer helps many.
hii.. so did u get any solution for the problem ?
i am facing this problem since one month. i tried rebooting my phone many times. i even tried factory reset. but nothing has worked till know.
if u have any solution please inform me.thanku

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?

Try to flash aex or lineage. At advanced wifi settings they have a region setting. Choose China and tell me if it helps

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...

Another WI-FI issue

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.

Is the US version affected by this?

No idea, but if people stating it's Snapdragon 835 issue are right , US version should also be affected. I'd rather ask an owner though.

As I recall there was a wifi lag problem with the first couple of builds, but I've had no issues with wifi since November. So perhaps it was fixed in a firmware update?

I've updated to .145 a few days ago (branded rom) and wifi connection seems to have improved, no more hangs. It might be different router in use, so I'll confirm when I'm back home so that I test in on the device I've had problems with.

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
