[Q] Xperia Z: Serious WiFi/Bluetooth Clashing & Crashing Issue - Xperia Z Q&A, Help & Troubleshooting

Hey guys,
I'm having zero issues with WiFi when using it on it's own, however, when using WiFi & Bluetooth at the same time, I'm having major problems.
I've contacted Sony, who suggested a software repair using PC Companion. I did this and the issues were resolved in the short term, but they've come back pretty hard.
So, this morning, I gone done a bit of a stress test on this, and here you go;
* Time is 12:27pm
* Battery on 62%
* WiFi has been on since 10am, for 2 and a half hours, and has NOT disconnected once.
* I've just turned on Bluetooth.
* Smart Connect starts up, connects to MBS-100, starts playing.
* Now, I will commence browsing.
* Time is 12:31 - 61% - Bluetooth disconnects.
* Time is 12:32 - Bluetooth reconnects, walkman continues playback.
* WiFi adapter active, however I have zero internet connection.
It took 4 minutes to disconnect...
* Time is 12:34 - Bluetooth still turned on and media player playing over MBS-100.
* Battery is 60%
* Turned off the WiFi adapter (as it is still on, despite no connection).
* Turned WiFi on again.
* Internet connects, browsing commences.
* Time is 12:38 - 59% - Bluetooth disconnects.
* Bluetooth reconnects - Walkman continues playing.
* WiFi adapter still active - NO CONNECTION.
It took 4 minutes that time again!!! And now I will repeat this one final time;
* Time is 12:40 - turning WiFi off... Turning it back on now...
* Open browser. Start to browse.
* Checking out Kotaku, Gizmodo, Engadget, Techcrunch, Xperia Blog and one or two other bookmarked mobile websites...
* 12:48 - starting to experience issues loading pages, some are loading very slowly...
* 12:51 - Pages not loading, Bluetooth disconnects. Bluetooth reconnects, music continues playing.
* 12:52 - WiFi adapter still turned on - NO CONNECTION. 'Web Page Not Available'.
Took 11 minutes this time.
WiFi settings says my router/network has been 'Saved, secured.' But has disconnected, when I tap on it it asks me if I want to Cancel, Forget or Connect. Tapping 'Connect' does nothing.
So I'm losing connection to my router/network every couple of minutes (4 mins, 11 mins, 20 mins...) while Bluetooth & Walkman are playing, and it will not reconnect. Can only be reconnected manually by disabling the adaptor and turning it back on.
Any feedback would be great... If it's a matter of changing things in my settings... I notice an Auto IP support opyion which 'Assigns Auto IP address if DHCP fails' (currently unchecked) which I haven't turned on, as I have no idea what it does... During these tests, Location based Wi-Fi is turned off, location services were turned on. I had the issues previously with location services turned off, so it's not this.
Appreciate any comments!
Thanks,
Willy

Any comments, suggestions, thoughts? Anything...?
I've tested this again with Auto assign IP on and off, and I experience the issue with both settings regardless, every 4 minutes.
Seems to be a pretty serious issue, my phone crashed and rebooted twice today while doing these same tests.
The second i turned the Bluetooth adapter off, after the WiFi crashing, the phone froze, went black, and rebooted.
ANY help or comments or thoughts would be great, thanks.
I'm at a loss.
WiFi is perfect on it's own, but in combination with streaming over Bluetooth, I get nothing but FAIL...!!! Every 4/5 minutes as per the tests detailed above in my OP.

In my opinion id get it replaced with a new Xperia z
You could do repair via pc companion
Or hard factory reset.
Heres one try disable LiveWare manager.

Have you tried using different BT devices and on another WIFI network?
Also try and do what DarkKrypt suggested, if you still have the same problem after the factory reset, bring back your phone.

Thanks both!
Thanks both you guys!
I have repaired the handset using PC Companion, tried resets, at the recommendation of Sony Support, however, the issues returned a few days later.
They have since suggested I send the phone to them for repair, which will take at least 7 days.
However...
I tried with WiFi on and streaming over Bluetooth to my MBS-200 last night, and couldn't replicate the issue. I'll try again, but it seems I'm only getting the problem with the MBS-100 (first generation).
Maybe it's some deep rooted coding issue or Jelly Bean Bluetooth protocol that causes issues when connecting to the MBS-100?
Although I doubt this is the case, because Bluetooth has no issue with the MBS-100 when WiFi is off.
It's only when WiFi is turned on that I get the issues detailed in my OP above...
It does seem to be a pretty strange one... As I couldn't replicate the problem with the MBS-200 last night, although I will try again. The phone is perfect in all other aspects, LED perfect, WiFi perfect, Bluetooth perfect, etc. So I doubt this could be repaired, as it seems to be a more deep rooted issue regarding compaitibility with the MBS-100...
If I have any similar troubles with the MBS-200, I will report them.
Thanks for your thoughts in the meanwhile, and appreciate any further comments or feedback!
With regard LiveWare / Smart Connect, I will try the MBS-100 with these disabled and see if the problem continues. Not getting the issue with the MBS-200 though it seems, with Smart Connect enabled.

id send report to sony about the issue with mbs100 maybe they discover the bug and fix it in the next update

thanks
Sony aren't that helpful, the admins on Sony Mobile put me through to Sony in Ireland, so put me through to the wrong people.
I've reported the issue, so they have my details, the issue I'm experiencing, they just want me to send them my handset, and I
don't agree that's required, because it behaves normally at all times, apart from when connected to MBS-100 over Bluetooth while connected to
WiFi. I've told them this, it's clearly a bug, as the Bluetooth and WiFi work perfect with other devices, and independently of each other.
Other users on talk.sonymobile.com have also backed up the same issue I'm experiencing, without using the MBS-100, and that as a rule of thumb, they can only use Bluetooth or WiFi independently of each other.
So they have acknowledged, and are well aware of the issue, my thread on this subject is the most popular thread on the Sony Mobile Xperia Z forum.
I'd like to test this a few more times over WiFi and with the MBS-200 and maybe another Bluetooth device, before I can possibly come to the
conclusion that it's something more than an MBS-100 compatibility issue.
Just for transparency, I've tested the Bluetooth/WiFi/MBS-100 issue with SmartConnect turned on and off, and the problem happens regardless.
Other people elsewhere on the net have indicated that this is a JB 4.1.2 issue, and have experienced the same thing with Asus products.

from my side i never had wifi problem except a perfectible low signal but work perfectly untill this weekend
now i'm not able to switch ON the wifi and the bluetooth
the "virtual switch" when put to ON is in light blue instead of bright blue and came back to OFF
same for the bluetooth
the only thing that i've made special this weekend is to connect to facebook application not yet done since i have the phone ( 2weeks ago )
i'm with the C6603
when i scroll down the top icon bar sometime i see the wifi icon trying to connect and finaly nothing
i would like to say that it doesn't linked to my wifi router or something external to the phone because it simply not activate wifi and bluetooth so not able to see any devices
i've not yet try a factory reset because i don't want to loose things

Smart Connect
Have you guys tried force stopping Smart Connect and then clearing data for it?
I had a lot of problems with wifi disconnects and now that I come to think about it I had some problems with bt in my car also but when I did the steps above it started working perfectly again(I don't think I even needed a restart of the phone).
If Smart Connect is the culprit for more people then Sony Mobile should really check out what the heck is happening with smart connect that make wifi/bt stop working correctly.

Bluetooth/wifi conflict for xperia z
EXACTLY THE SAME PROBLEM GUYS...
Unfortunately there's been a serious issue with the bluetooth and wifi working together.
Notice, it is happenning only with bt headset device not eg. when pairing with another phone and send/receive files.
Unfortunely, sony is not dealing with that professionally. They have a nice product which they should support it and for that issue they should change the phone. i have that issue after i send it to sony service and they told me that they fix it, but nothing...
It is happenning form the beginning and because is the second xperia z (the first got damaged the first month...), i must say that with the same bluetooth device sony mw1 i had NO problem at all in the 1st xperia z but in the 2nd xperia z it was conflicting from day 1...:crying:
If you have any idea, or you solve that issue please reply.
thanks

Exactly the same problem with my one too. This is a serious bug from the 4.3 - .569 version rom. Sony is not thinking of fixing it soon for Xperia Z, but new version 4.4 Kit Kat is on its way with awesome theme and performance. However, z1 did get the better 4.3 update and the launcher theme is simply superb. I am jealous, but if there are any techy guys around, they can move back to 4.2.2 until Sony releases the new update. Unfortunately, this is the only solution. Otherwise, DEVs in this forum must port bluetooth and wifi drivers from 4.2.2 to the 4.3 version and release the rooted stock roms for us

I've gone back to 4.2.2 due to bluetooth issues. Tried most of the roms on 4.3 and it just wouldn't connect right. Will wait for 4.4 now

Sorry guys, I was only having this issue on 4.1.2, I'm on 4.3 now and not experiencing any issues. Bluetooth skips occasionally but that's all.

Hi Stewartk,
For the same reasons as you I tried reverting to 4.2.2. ( Xperia Z 6603, 10.3.1.A.0.244/ 10.3.1.A.2.67 ) but in all cases the Bluetooth and WiFi are ok BUT ... the mobile data transmission behaves funny - only Youtube can access the Internet, all other apps think it is not connected or cannot connect to specified (working) web pages. Could you hazard a guess why this might be so ?

I'm having the exact same issue on 4.4.4,
wifi works fine alone, as soon as Bluetooth is ON, wifi starts to be weird.

5.0.2 and still same issue. i guess it is because of hardware.

5.1.1 Having very similar problem as OP. Having a bad/low wifi signal does interfere with my Bluetooth, but it's not disconnecting wifi. After like one minute of talking on the phone with a pair of Sony MDR the voice quality starts deteriorating when on wifi and works like a charm without, same when pairing with a soundbar platying music

If you can unlock your bootloader you can flash Zombie kernel and this should all be fixed.

wifi and bluetooth

first i bought a sim-free kaiser - had problems getting bluetooth to work when wifi was connected - got so pissed off with it i sent the unit back - now ive got another unit (a vario 3 this time) and i am having the exact same bloody problem - what the hell is going on? cant this device do bluetooth and wifi at the same time? i want to stream music over wifi to my BT stereo headset FGS
Any equipment wether it is a phone, laptop or PC will have somewhere in its manual that recommends WiFi and Bluetooth are not used together. Both systems run on very close frequencies and cause interference to each other.
The problem is enhanced by the proximity of the Tx and Rx of each system within such a small unit as a phone or PDA.
I wanted to do the same as you and found BT falling off due to the high rate of packet retries on each so reverted to wired headphones.
Add a cellphone TX and Rx to this also and you have one NOISEY set of close by systems.
i have heard reports of people using both together in harmony on the kaiser - and a lot of people who own other devices (ie htc universal, sony ericson, p990i etc) do not seem to have this problem
i appreciate that bluetooth and wifi share the same frequency bandwidth and this will inevitably cause packet loss - but not nuke it all together! afaik bluetooth hops 1600 times a second (or smt like that) all over the spectrum, where as wifi tends to stay within a certain band?
Lately, I've had a little trouble with using WiFi with A2DP on my Jabra BT8010. Periodically, I get dropouts on the sound, which seem to be associated with WiFi disconnects -- I lose the WiFi momentarily, then as it tries to re-connect to the AP, I lose sound. Not a range issue -- this happens even when I'm right on top of the AP.
I haven't had any problems with WiFi & BT in handsfree or HID modes, just A2DP.
guess im just really unlucky :/

A2DP uses 200-400 kbps, while handsfree / HID only a fraction of it.

You're not alone. There are 5 reports of this in the HTC Wiki, and I've run into it myself. If I'm using wifi and I answer a call with my bluetooth headset, WiFi simply stops working. Likewise, if I'm using the headset and I try to switch on WiFi, the device can see the network, but can't connect and will eventually drop the network configuration and prompt me for the WPA passphrase.
Edit: I tried upgrading to the 1.27.12.17 radio ROM, but no joy.
I'm having the same problem, but I'm using the ROM that the Kaiser came with. Has anyone tried using Dutty's ROM or something?

Do us all a favor and give HTC a call and report the problem. I have nothing against the cooked ROMs, but just like the video drivers, it would be nice if there was something official from HTC:
+1 866 449 8358
Just wanted to say that I too have the same Bluetooth + Wifi problem. When I have Wifi on, it's nearly impossible for me to connect to my PC with a Bluetooth connection. I have only had some luck when I established the bluetooth connection and then turn on Wifi.
HTC says they're trying to reproduce the issue and will get back to me in the next day or two. Again, I strongly encourage you to give them a call.

Just called them, and the woman on the phone basically told me not to expect any updates within the next few months, if ever. What the hell is that about? To that I responded 'so basically you're saying that you don't support the device'... She kind of dodged the question, but it seems to be that way. We're kinda on our own... Which is unfair, but this verification removes any remorse I would have about hacking the **** out of my phone. So now that it is verified that we're being hung out to dry, do any of the ROMs address this issue?
As will all other customer service organizations, if you don't like the answer, call back.
Getting them to reproduce and recognize the issue is the first battle.
Smart Answer mate. I have an SDA and haven't noticed that problem so far, I'll try to see if its been happening un noticed. Anyone know where i can find A2DP profile for the SDAII ?

Im using Dutty's ROM and have the same problem.
Has this issue been resolved with the new Firmware, to anyone's knowledge?
The recently released AT&T ROM does not fix the issue. Support told me they have sent a report back to engineering. I'm going to give them 'til the end of the week before I call them back.
Any Updates or fix regarding Wifi and Bluetooth interference on the HTC?
Let me add to my own finding...
I have 3 laptops and 1 PC that is on the WiFi. If my HTC Kaiser craps out using the Wifi with bluetooth. It takes the WHOLE entire Wifi network down( for about 30sec to 1min). I can see all my laptops and PC dropping Wifi and trying to reconnect.

[Q] BlueTooth going on/off repeatedly

okay, well forst of all my wifi wouldn't work until I turned on my bluetooth fo what ever reason......
now after rebooting FRO6 the bluetooth keeps turning off and on and subsequently my wifi, this is particularly annoying. I've posted on the release thread as well about the wifi.
What the hell? has enyone had this kind of behavior before, I've installed a few apps but nothing unusual or third party...

[Q] [Xperia V] [9.2.A.1.210] Unstable wifi

Hello,
I upgraded my phone to the unbranded/Nordic version (9.2.A.1.210) from the original 9.1.A.1.140.
While this brought many positives (support of BLE for my forerunner & good battery life), it also brought some negatives:
- A terrible clicking noise when the camera is auto-focusing (clearly a known bug in all JB version ...)
- A very unstable wifi
On this second issue, I have not seen any other report of the issue.
The symptoms are quite basic, after some time (around couple of hours), the phone will no longer associate with any wifi.
The only method I found was to enable/disable the airplane mode to restore normal wifi operation ...
I have installed wifi-fixer for having more details, since the wifi is looping on the association mode (could be authentication errors on these known network). Of course, all authentication info are correct as the phone will connect properly once going through the airplane mode ...
I also re-flash that firmware, from the .ftf but also forcing it from Sony SUS ...
At this point I reverted back to 4.1.2 as I'd rather have less features but reliable one (wifi is flawless now - well just as it should be ...)
Anyone else with the problem ? Any solution identified ?
Same problem Here
Would you please point me to the tutorials to get back my phone to 4.1.2, thank you?

Just follow the guide in the general section (i.e. retrieve the right .FTF file and use flashtool), this is very straightforward.
Tried with the ROM from Singapore, same issue ...
=> Association rejected on all known wifi
(using the power button to cycle the airplane mode restore the wifi for 10-15 mn)
Any advice on how to troubleshoot ?

Maybe it's your wifi that gives problem of compatibility when you're on 4.3
Try with another wifi if you can..
And try to change some settings of your current wifi like number of channel, kind of encryption, and so on..
In fact the problem is more complex as sometime my wifi appears to be ok but I do not have any connectivity ...
Now, I believe I found some interesting infos:
=> prb is directly tied with usage of Bluetooth (especially 4.0 BLE)
When the wifi is 'broken', disabling BT will indeed restore normal wifi operation ...
I could not notice the issue before since Android 4.1.2 do not support BLE ...
I've notice others thread reporting WIFI/BT issue (notably around support of smartwatch)
In my case, I'm trying to have my garmin GPS Watch to pair with the phone, this is were the prb can be easily reproduced
I have the same issue! That damned Association Reject!
I can confirm this is due to Sony 4.3 as Wi-Fi still work normally on my other 4.3+ devices (Nexus 7 2012, Galaxy Nexus)

Same here
i have tried numerous methods to fix this so far no luck..im on ub flashed 2 3 roms even stock rom with sus
One observation ...
This time, running stock .210 but not installing my BT4.0 Application (Garmin Connect), I only had the Wifi/BT issue once ...
I will install the application but not connect to my watch (Forerunner 620), to see where exactly is the breaking point.
After all these, I will certainly consider unlocking my bootloader and try the Omni ROM (as I see Walter79 is extremely active)

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 :/

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

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.

Are major problems solved in the latest firmware? (Restarts, wi-fi & BF dropping...)

Hi,
I want to buy XZ1 compact but I am reading this phone is restarting on its own, and has wi-fi and bluetooth problems. Can anybody please say, if those or other "critical" bugs are solved? I searched but it is hard to say for sure...
Basically I am quite depended on the phone and I really want it to be reliable. My current Motorola restarted maybe once in three years, so I am bit nervous about this.
Thanks
I'm on the latest firmware and I don't have any of that.
That said, I was on the November one for the last few months and also never had any of that.
That's the problem with forums like that, you're likely to only see the rare negatives of any device.
No issues for me.. smooth as butter.. great battery life.. LDAC working flawlessly with Sony headphones etc
Just wish I could turn the charging LED off
Also keep in mind if you unlock bootloader and load custom rom you're on your own. I havent gone that route this time and have had literally 0 issues in months
Okay, thank you, it seems it will be fine. I won't do custom rom but yeah root + xposed is a must for me.
I also got dropping WIFI. Really annoying and nothing seems to fix it.

Wifi working fine here. Check the settings on your router.
The restarts seem to be fixed. I think it was a regression with the previous one or two versions. The phone was fine, then it went from one or more a day, to none with the latest update. Wifi hasn't improved, but I did not find it that bad to begin with. Once it connects, it stays connected. It's that original connection where it sometimes decides "wifi? I don't have a wifi radio." Bluetooth is still terrible - works fine with a BT speaker, but is nearly useless with a car stereo.
Only 1 problem persists - Smart Lock don't work, it just a blank page. Can be resolved by restarting the device.
