Only getting ~50kb/s download speed while using Bluetooth and wifi - Xperia Z1 Q&A, Help & Troubleshooting

So my problem is that I only get a downstream of ~50kb/s when I am using Bluetooth. Like connected BT headphones and Youtube. If I switch to 3/4g I get normal internet speed. My router actually tells me that the device is limited to 1mbit while every other device gets their full bandwidth. If I disconnect the headphones, everything is normal as well. Headphones work fine everywhere else, even on my laptop (Also WiFi + bluetooth) I tried like everything I could do routerwise like switching channels, changing encryption. What else could I do?
I recently updated to 4.3 (from 4.2) and the problem still exists.

Does your router have a Bluetooth coexistence mode? Bluetooth and WiFi are in the same frequency bands and can sometimes fight. No matter what WiFi channel you use, it's still the 2.4G spectrum, which Bluetooth stretches almost all the way across (2.4 - 2.48). Encryption is irrelevant (and maybe make speeds worse).
It does seem more like a device specific issue, though, so I would recommend setting factory defaults. If that doesn't work, you can try re-flashing an FTF, but it may actually be a hardware issue.

Fun thing is, the it works on my laptop. It's connected via wifi and I connect my BT headphones and I get full speed on wifi. On my phone it works like a few seconds and then it switches to 1mbit. My router has no functions for BT and unfortunately it doesn't have a 5ghz mode.

It's probably just related to your phone specifically, then. Try the steps I suggested and see how that pans out for you.

Ugh I hate reflashing or resetting stuff in general. Well since there us no obvious solution I'll try to find a solution. Thanks for the help though. I'll report when I found the solution.

[Q] Bluetooth audio streaming problems

I've had my Nexus S for a couple of weeks now and am really enjoying it.
However, bluetooth audio streaming is proving to be a royal pain.
I am using a Motorola T505 in my car.
The symptoms are pretty consistent.
If I reboot my phone then the audio will stream over bluetooth flawlessly.
If I try to stream without rebooting the phone then it will stutter and stop randomly.
My diagnosis is that there are processes running on the phone that interfere with the bluetooth or take up memory that is needed for the streaming to work smoothly.
I have read that wifi can be a culprit, but even with this switched off I have a problem.
I know that my drive home takes me through areas with varying degrees of reception. The phone does switch from 3G to edge to gprs and there are areas where the signal is quite weak. But if this was a problem then it would have an effect whether I had rebooted the phone first or not.
I have tried installing Advanced Task Manager and using this to kill programs that are running but this does not prevent the problem. Even if I am able to get free memory up to 120mb + I still get the stuttering.
I'm determined to get to the bottom of the problem as it is just about my only issue with the phone and it is a PITA to reboot before my commute.
I am aware that there are all sorts of processes running on the phone and using system resources but I don't know what is safe to kill and what isn't.
Should I use a different task manager?
Is there a particular app which might be causing a problem?
Any ideas on how I can troubleshoot this further would be gratefully received.
I am presuming that I am not the only one who has this issue?
Thanks

I stream via bt to my car stereo without any issues all the time. What is the audio bitrate you are streaming?
Sent from my Nexus S using XDA Premium App
I stream mainly podcasts. The bit rate will be whatever the default is.
Since I first posted I have had fewer problems with stuttering. I did uninstall poweramp. That may or may not have any bearing on things.
I now find that auto connection is a bit flaky. Sometimes it will connect, other times I have to do it manually.
Overall not the best experience but very nice when it works.

I have no problems streaming audio from my Nexus S to my car's audio deck (Pioneer P7000BT) and I play anything from my music apps (pandora, slacker, etc..) to my songs in my mp3 library. If you aren't on a custom rom, perhaps trying CM7 and a good kernel could help you narrow down your problem.
My phone's setup is listed below in my sig.

Bump!!!
Brand new Nexus S owner with the EXACT same problem, it's driving me nuts.
Unless I do a reboot on the phone or sometimes just a manual disable & re-enable on the bluetooth, it will keep having 1-2 second audio drops right in the middle of playback. I have a Kenwood KDC-BT838U deck. The bluetooth connection between the deck and phone never breaks. It never disconnects or disassociates in any form as far as I can tell. It's clearly a problem with my Nexus S only because I also have an iPhone 4 and it works flawlessly all the time (just not unlimited data on that phone!)
It's really annoying that others in this thread say they don't have the issue at all. I have streamed off Youtube HD and radio stations via TuneIn Radio.
It's super annoying considering I got the unlimited data package for exactly this reason.
It's only been 4 days of having the phone so maybe I'll go try and exchange tomorrow.
Just my luck

Try disabling wifi while you streaming through bluetooth. Wifi radio can interfere with some headunits.

First thing I tried!
I've moved on to cm7.0.2 and it is still a bit flaky, although not as bad as it was.
There doesn't seem to be any pattern. Sometimes it's fine other times it's not.
Interesting, I have had a Kenwood KDC-BT945U for sometime now and have used it with many different phones. My Nexus One had a very flaky connection to it, my HTC G2 connected fine but would give me audio drop outs randomly every few minutes which was SO ANNOYING, Iphone work just fine and my Nexus S works without issue also. I had assumed it was just an issue with HTC phones. Are you currently running a custom ROM? The only time I was ever able to get my Nexus One working the way it should was to use a Sense Rom.
I upgraded to CM7 and it's as bad as ever, didn't seem to help at all.
I also went through a full exchange at the store, and the brand new one straight out of the plastic did the same thing. Must be the phone itself is all I can think of.
All I have left to try is a new kernel, I can't figure out which kernel to update to if I'm using the Mobilicity AWS Nexus S
If you are having problems with bluetooth streaming and have a task killer installed... Uninstall it...
Task killers are problem makers...
Android has a built in task killer
Good news: I just saved 500 hundred bucks on a new phone by switching to XxXViRuSXxX
(So easy, a noobie can do it)
There is still no solution to this problem. I'm assuming nobody else here is using their Nexus S for bluetooth audio streaming often?
It has persisted through 2 exchanges which leads me to believe theres a problem with the hardware itself or something.
Rooted, custom kernels, nothing fixes it.
This phone is such a piece of junk, I'm hating it more and more every day

I use my Nexus S every day to stream music over BT/A2DP to my car stereo (Kenwood Excelon KDC-X994) and it works without any issues, and it always has since I got it. I've rooted it and am using a custom kernel and radio, but left the OS at stock 2.3.4. But it also worked fine with my head unit right out of the box before I made any changes to it.
I'm sorry I don't have any suggestions or solutions for you. In my own experiences it seems like certain BT chipsets just don't work well with certain pieces of BT hardware, so maybe there's just "bad blood" (so to speak) between the BT chipset in the Nexus S and your BT car hardware...?
Sorry I don't have any ideas to offer to try and help.
I also stream music over Bluetooth, the blackberry gateway device works perfectly for me, but it requires an AUX port
Sent from my Nexus S 4G using XDA Premium App
What app are you using? I saw you mentioned podcasts and I have seen this problem on my EVO with google listen if i initiate play from the head unit to continue listening. I saw this on stock and CM7. However I have not been able to replicate it as of late. have you tried a differnt program or even just restarting BT? That is what fixed it for me back then.
Hope that helps
To the Gentlemen having problems with Bluetooth streaming. I hate asking but have you tried a different device as the bluetooth receiver if possible? A lot of the users replying are using pretty nice head units and in my experience with my Golf ive had no problems. well thats lie.. i have issues with the turn by turn navigation audio not working. It cuts the music (as it should) but the navigation audio is either non existent or extremely quiet (yes ive checked the navigation volume on the device).
But yeah long story short just wondering what other bluetooth receivers you have tried. Good luck.

I have the blackberry little gateway as well. When it connects it's great (no stuttering etc), but my phone won't always connect to it when I get in my car. Sometimes turning BT on/off will then get it to connect, but it's random. The sure-fire way to get it to connect is rebooting the phone. Not sure why that is, but very annoying. Does your NS connect to your blackberry gateway every time without fail?

Ah that's a relief to hear actually ! I wonder if it's specific to the blackberry gateway, and some other brand A2DP receiver would not have the problem...

HTC One Terrible Bluetooth range .....

Friends ...... , HTC One it seems has a terrible Bluetooth range ....... I have a Logitech BoomBox (Bluetooth spks) and a Belkin Bluetooth receiver connected to my AVR. In both the cases, when connected to my HTC One it looses audio in just couple of feets. Specially with belkin receiver. But when I tested the same with my iPhone 4, it works perfectly, till the Bluetooth's designated range of 30 feet (10 meters) ... with both Belkin and Logitech ....
so it has something to do with HTC One's Bluetooth.
People with HTC One and having any Bluetooth audio device, please test this and report if you are also facing the same issue, Or is there something that I can try to increase the range. Its pathetic, 2-3 feets at the max. I am bitterly disappointed with this ..........
Regards.
Sammy
I think that Android 4.1 had a BT flaw that was fixed in 4.2.
so this means its more of an android issue than HTC One........ any alternatives to improve this, till we have an 4.2 update
I was using bt audio yesterday and it was horrible. I did some googling, try turning off wifi before you connect to the speakers, it solved my trouble straight away. I found if the music was playing when I turned wifi back on it would still be ok. Might help?

Jiggle .... my friend, you made the day for me, how so ever strange may it seem, it did work .... ..... I switched of my wifi and then connected Bluetooth to Belkin receiver and vola!! :victory:... no drop outs and was able to use BT at full 30 feets, and then if I switch on the wifi later all is well.
Strange, if wifi is working before I connect BT, it drops and is very uneven ......... must be some bug, but anyway, solution is not as irritating as one might expect.
Thanks again Jiggle, for you input, saved me a great disappointment.

whew you had me in a panic here. (o; I'm still a little traumatized from my asus T201 wireless issues.
The Wifi/bluetooth issue is a drawback of the aluminum body design of the One. Bluetooth shares an antenna with wifi transmit. I believe wifi receive shouldn't interrupt bt though.
Then there should also be a problem if I switch on wifi after I connect BT. ,... in which case it works. It only creates a problem, if the wifi is first on and then I connect BT. ...... which is strange
Just for information. I had 3 htc, desire hd, sensation, onex and ALL had problem with bluetooth, weak signal, using a headset with the phone in my pocket already failed. I now have a note2 and this problem does not occur, being used in the same situation. So ....

My m7 (TrickDroid, elementalX 0.11 default overclocking and undervolting) is having the BT issue whenever wifi is on, regardless of whether I connect the BT device while wifi is off, and regardless of whether audio is playing when the wifi is turned back on. In other words, on my device, BT really really sucks if wifi is connected, period. Any suggestions other than not to use wifi if I want to use BT?
Update: My router (Netgear wnr2000v3) seems to use 2.4 Ghz channels. Any thoughts about whether swapping the router with a dual-band or 5 Ghz channel router would work around this issue?

I did pick up a new dual-band router and set up the phone to connect only on the 5Ghz band, and it worked! No more bluetooth issues at home. So if you run into this issue, a temporary workaround until (hopefully) HTC/Google provide a fix is to avoid the 2.4Ghz band.
Strangely enough, my Bluetooth range keeps decreasing with each software update. When I first bought this thing, I was generally impressed with how far I could walk from my BT speakers. Not as good as my evo 4g or 3d, but decent. Better than my gs3 and gn2.
Now I tend to make it about 5 feet or so with minor cut-outs while using apt-x. If I put my hand between the signal at 10ft, I can stop it completely. If I touch the upper-right of my phone with my thumb as I hold it in my right hand, I can kill the signal as well. Very much an antennagate going on here just like the iPhone 4.

[Q] Bluetooth issues

Hello everybody,
I hope this doesn't repeat an answered question.
I have a well maintained p880 (stock JB, rooted, frequently factory-restored).
I tried to connect to a bluetooth audio receiver. Connection is easy but the sound breaks very frequently. This is clearly not the receiver's fault because sound transmission from an iPhone or a laptop is perfect.
I have no reference to the phone's bluetooth capacities because it's the first time in 2 years that I try to use it.
EDIT: I just found out that turning off wifi solves the problem. This, however, is not really a solution.
Does anybody have any experience with it? Is there a way to improve bluetooth performance?
Thanks!
Im on Beanstalk and the Bluetooth connection with a car radio does break as well very often (about every 20 secs), WiFi is turned off always. Maybe it's the Bluetooth chip itself that has such bad connection.

[Q] Anyone else having problems with the 3T and car bluetooth?

Mine stutters when connected to my car's headunit. It's especially bad when in a call. Wasn't a problem with my Note 3 and doesn't happen on other bluetooth devices.
I haven't had any Bluetooth issues other than the fact it eats a lot of my battery throughout the day but that's a usage issue than anything else. I also use Bluetooth in my car while commuting around the city. If the audio stutters, that often means the connection isn't stable therefore move closer or remove anything in between.
Does playing a track before the Bluetooth connection is established make a difference?

Not really. It cuts off for a second every minute or so. The phone is right in front of the headunit so i dont think distance os the problem. The case is plastic so that shouldn't be causing interference also.

I'm having the same issue with Bluetooth not connecting/cutting out when it does.
OnePlus 3T
Android: 7.0

Car is a 2016 BMW 328i
Not a problem on my Optima. I actually had to tune it with an equalizer app because stock equalizer raises the Treble louder then the bass. All normal now but not cutting. Had problem connecting phone automatically for a few days but went away

Use my device with a set off speakers and to connect to my in car audio system and I don't experience the problems you have, sometimes I need to stop and start my music a couple of times whilst it reconnects again if I move between devices but after that it stays connected and working.
my phone has trust issues with my car. it always requires a re-pairing whenever I try to establish a connection (means, whenever I enter the car, and try to connect, it requires me to pair the same phone again)
Working perfectly with my car. Maybe updating car stereo firmware could help?
I will try to see if there is an update for the car master today (their site seems to be down atm). I have had it work at times but it usually has issues connecting and will stop/pause sometimes out of nowhere. It's really difficult because I need a Bluetooth connection when driving but it gets to the point that I need to forget and repair my phone everytime I drive....
I just got my my OP 3T . I had issues with it connecting to my VW Passat. Then I read the following at the car's BT manufacturer's FAQ
Some versions of Android use a deviate pairing method. This can cause the problem of a failing connection. The solution is the free tool Bluetooth File Transfer (Android) for a better Bluetooth connection. It is available at Google Play. Establish the pairing once with this app and from then, everything should work as normal.
So after this app connected for the first time to the car's unit, the phones own BT software also started connecting without problems when I turned the car off and on subsequent times.
Might be worth a try.

BT disconnecting while hotspot on

Hello,
from MIUI 11 i am experiencing issue with BT devices disconnecting while using wifi hotspot. Once hotspot is active everything works for a while but then BT stops working and disconnects devices.
IT IS present Also in custom roms. Anyone Has this issue and know about some fix?
Many thanks.

Is your hotspot in the 2.4 GHz band ? If the answer is yes, try 5 GHz.

It's mostly unrelated (at least with phone) but I recently started using a new small PC. The bluetooth disconnected too easily, even at less than 2 meters, a slight move of my head(phone) was enough to cut the music. Then I disabled the Wi-Fi interface and Bluetooth connection became robust even in the next room several meters away. That's probably because Wi-Fi and BT uses the same 2.4 GHz band.
Concerning Xiaomi smartphones, I use them everyday to listen to music while Wi-Fi is on (either in the 2.4 or 5 GHz band) and never observed a disconnection (xiaomi.eu or other custom ROMs). But I haven't tried in hotspot mode.

yes it's work as it should until i enable the hotspot, even then, it works sometimes for like an hour and then it starts... solution is airplane mode on/off and it works for a few again.
i use this a lot, as i do hotspot for kids and wife in the car, and i also work a lot remotely and this disconnects everything from BT audio to watch and it's really annoying. :/

After that I turned on hotspot in the 2.4 GHz and I havent observed a disconnection yet (after 15 minutes). But I live in the countryside where the whole Wi-Fi spectrum appears almost unused. I usually can detect only one other access point with a very weak signal. So, even if I was able to test for several hours, it wouldn't prove anything as your use case is very different. It may come from interferences on the same channels used by others while your vehicle moves. I don't know if we can control what channel is allocated by the hotspot but it's probably dynamic. I guess that when you switch off then on, it just select another less used channel then it works again for a while.
