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.
Hi everyone.
I bought a sgs about 7 months ago. Since I bought this phone, I am having some bluetooth issues with it.
The problem is;
when you first try to connect the device with any other bt devices, it connects without having any problems and operates normally.
Then, when you disconnect sgs from the device, it never connects again. it does not even search for the nearby devices. you can also not unpair the previously connected device, the command "unpair" does not work.
the 120 seconds counter, doesnt count down when you switch the phone to visible mode.
I tried to re-boot but it did not work.
I re-flashed the same rom, it did not work as well.
I changed the rom with another one and flashed 2.2.1, but it s still the same.
the only way, to make the device connect with a nearby device is to re-flash the rom and it only helps me to connect to any device for just 1 time. then bt becomes useless when you disconnect and to re-connect, you have to flash the rom again..
Please help me in solving this.
Honestly I have similar issues with my phone. This thread fixed the connectivity issues: http://forum.xda-developers.com/showthread.php?t=795691&highlight=bluetooth
However, my phone consistently drops its connection...very annoying.
Honestly, I never had a connection, thus, I am not familiar with the saying "connection droppings"
I tried the things written in the thread but it did not work. still the same and really annoying.
Hi, did you solve this issue? I'm having the same problem on 2.3.3. and it's very annoying...
well, my wifi is acting wierd... reception is good and it doesn't disconnect too often, theres just this little anoying thing!
everytime roughly 3-4 days after i flash a new rom my wifi simply refuses to connect to network, and not a specific one, any network at all!
and it stays like this for a couple of hours and then all of a sudden it picks up a a networks and it works fine for a while, untill i happens again...
i've tried restarting and taking out the battery and turning the wifi off for a while, nothing seems to help, he just decides on his own when he is whilling to connect again....
if i flash a brand new rom the problem disapear for a few days but then it comes back... i'm assuming it has to do with some sort of a cache that is filling up with loads of crap and ruining the wifi activity but i tried googling for this and found nothing..
ideas anyone? (btw this happens on all roms: stock, existenz, beanstalker etc...)
its a hardware problem and not so uncommon look here

if you can take it to a customer support and if you cant sell it and again if you cant, then just get along with no wifi/bluetooth/NFC check all of them you should have problem with them too

absolutly not related, my NFC and bluetooth works just fine, i don't need to press hard anywhere...
and my wifi works just fine after a fresh rom install... so it's defenetly a software problem...

to me that sounds like the start of it because mine was the same at the first few days flashing a new rom or something would help alot but then i just found out the only thing that was helping it to get fixed was the heat from the device not the rom, but it doesnt hurt to play around with it a little so go ahead and try some other roms or repairs.
you see good reception for wifi
you try to connect
at the authorizing or connecting you will see only one point of signal and connection would kinda like disappear.
this is how it was for me but at the first days it was random it was connected good and ready, when i would left the phone in stand by after a few minutes it would DC, so i thought its kind of a sleep mode malfunction or something but after a few days almost 1-2 weeks it turned out to be hardware problem like ohers so if you see any symptom like that start looking for service centers.
but i hope it would be a software problem for you, so good luck.
Well, once he connects he stays on for days, no problem there... Just sometikes he refuses to connect... Pressing the nfc button doesnt help...

What Wi-Fi channel is your network on and have you tried 5GHz?
Didn't look into those things, but it happens with all networks except ones without passwords
Sent from my C6903 using Tapatalk
Have you tried deleting wpa_supplicant.conf in data/misc/wifi and reconnecting to the network? (this will delete all saved passwords and settings for known wi-fi networks) also try to disable Auto IP in advanced wi-fi settings
Well the phone is qith my sister now, I got a new z1 so far wifi worka for her, it stoppes for a few hours yestarday but came back, I might try to flash. 310 and see if it works better with it. And the Wapa_sup sounds like a good idea. Btw z1 is also jittering some with wifi, it's a global Sony problem...

temp solution?
Well, it is probably a hardware problem. I have had the same problem, everything looks fine, but you can't connect to any network.
So, searched, reinstalled, etcétera, nothing worked. Untill I read a crazy solution link://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/xperia-zr-wifi-association-rejected/td-p/516275/page/4
and found out that if you put pressure on the back of your pone right at the NFC chip, with a finger or so, the Wifi will come alive again.
Personally I had to hit my pone's back at that exact spot with my finger (for not damaging it with excesive force) a few times, but then suddenly it worked.
So, I am convinced it's a hardware problem. Hope it works for other people too.
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

If you guys any suggestion any hope please let me know.

Hi Guys,
The wifi calling feature on My T-mo Galaxy S6 is not working at all. Whenever I try to enable it, it gets stuck at enabling.
Toggling Wifi on/off or rebooting the phone has no effect.
Can anybody help?
BTW I am on G920TUVU2DOF8 build, rooted, TWRP recovery and UniKernel.
Thanks

I have the same problem, unless I'm at home on my cellspot. Connecting to anything else is a no go. Still 5.0.2 rooted with ping pong for now. Sucks to have a major perk like WiFi calling not working for a flagship phone. Anyone have any clue how to fix this?
So is there nobody who uses wifi calling or wifi calling is working great for you guys?
I can't believe that there are not many complaints around this issue. The T-mo signal in my house sucks and I was kind of hoping that I can use the wifi calling feature instead.
Mine seems to work fine.

Try calling your phone from another source and see if that congratulations you have used wifi calling message pops up.
Possible fix
So I know this is a dead thread, but I found a possible fix if the airplane mode doesn't work. I shut the phone down, pulled the battery out and hit the power key a bunch of times. Doing this without the battery seems counter-intuitive, but it discharges capacitors when you do it on laptops, so I thought I'd try it on my phone. Put the battery back in, started the phone and wifi calling worked again.
This actually works for me. I just installed an App called TalkaTone(FREE but requires registration) and called my T-Mobile number and let it ring for a few times then hung up. Wifi calling finished enabling and started working.
Still no solution
I've been using note 3 for 4 years and currebtly it has phronesis rom 7.0.
Last week, after i charged with my powerbank, suddenly wifi stopped working, stucked at 'enabling wifi'. I rebooted a few million times, cleaned unnecessary apps including the last ones, hard reset, reinstalled rom, shook it, dropped it to the floor, threw it to the wall, but didnt help at all. And i thought it's a got broken as it's already 4 year old phone.
A few days later, when my charge was at 3%, the back of of the phone, right next to the camera heated too much, despite i was doing nothing, i got panicked and remowed the battery.
10 min later, placed it again, booted the phone, and tadaa, wifi was working, the back side was keeping cool, phone was smoother and charge level was %35 or so.
Then i thought, wifi issue was not a hardware thing but instead it was related to wrong battery stats. When the charge level was again 2% i removed tge battery again, waited fir a few min and placed again. It was again %25 percent,( didnt last long though,) but wifi again was not working.
Moving from that point, i fully charged the phone, calibrated battery, removed replaced etc... but didnt work.
I deleted the file data/misc/wifi, it didnt work.
Afaik blutooth and wifi use a common chip and if wifi is failing cos of a hardware issue, blutooth is not supposed to work as well. Yet, my blutooth works fine. Just wifi.
I dont know how to fix it.
Try it
I have no S6 , but you can try the Wifi Calling tool .
