Wifi & Bluetooth at same time = buffering

So I have a issue, I experience buffering when I try to stream audio via Bluetooth To my Philips fidelio while on wifi. If I turn off Bluetooth the buffering goes away. Can Bluetooth and wifi not be used at the same time? I have a 2.4 ghz wifi router only. Also if I turn off wifi "use 4g" and just use Bluetooth the buffering goes away as well. Does anyone else have this issue?

This happens on many phones because the wifi and Bluetooth often share the same antenna since space is crucial, both operate in the same general frequency range. Not much you can do I don't think.

I wonder if I got a 2.4 & 5ghz router if that would solve the problem

i got the same problem: everytime i stream music to my bluetooth headset and leave wifi turned on my nexus looses wifi connection when the screen is turned off.

That's a great experiment to try. I remember back on my nokia n95 wifi and bt stuttered together cause they shared antenna. But surely 5ghz has a desperate antenna? Curious.

I have the same issue. If I keep the screen on it doesn't buffer. The best solution I have found is to put the phone in clock mode so you don't get screen burn in. I used tasker to setup a profile when the phone is plugged in.
I haven't tried the 5ghz wifi but heard that works. My phone sees my 5ghz router but it won't connect. I tried all the channels but I guess that's a different bug to sort out.

Just tried this and it seems to be working for me as well ... Thanks for your help
Did you try setting your phones wifi to 5ghz only in the advanced setting ?

I think Franco kernel updater has a setting to fix this.

I've noticed that when streaming video over HDMI with my Bluetooth mouse paired, it sometimes gets choppier than when I turn the mouse off. Similar effect I guess.

If screen on fixes this than that's a different issue than antenna sharing bandwidth problem. Sounds more like the android 4 power reduction bug kicking in throttling the CPU or data or something.

I tried that and it still won't connect although it sees the 5ghz. Not a big deal because the range on my 5ghz sucks anyways, i just wanted to try it and see if it fixed this issue.
I got the Phillips speakers as well. I'm a little disappointed by the slow charge and low speaker volume for the price, but it works.
I did an alternative setup for my dad with a pair of cheap computer speakers from Walmart and Bluetooth dongle from Ebay. I also got a desktop cradle with spare battery slot that does a fast charge. In total it ended up costing a lot less than the Phillips speakers and probably sounds better.

bluetooth interfering with 2.4ghz wifi on Tab Pro 8.4

My wifi on my tabpro 8.4 is fine until I connect my Bluetooth game controller to it.
It only affects the 2.4ghz part of the card though. i ran some tests and with the bluetooth controller turned off, my 2.4ghz wifi signal was perfect. As soon as i connected the controller, it seems to interfere and all the 2.4ghz wifi signals in my area disappear and reappear every 10 seconds.....as soon as i turn the pad off they all stay there indefinitely.
the pad does not affect 5ghz signal though.
i wonder if there is a fix for this or if it is just a hardware issue?
I know it is just this tab as when i run the same tests on my galaxy s5 there is not interference from the BT controller
Can anyone help me?

I just got a keyboard and mouse, bluetooth. They work awesome but they kill the WiFi on 2.4ghz. I don't have a 5ghz access point at home and none of the places I'd use it have 5ghz right now so it sucks. I'm guessing that no one responded because I don't think k it matters if you're on an ios, Android, or Windows system they both run on 2.4 and conflict and cause issues. Bummer.

Bluetooth runs on the 2.4Ghz frequency and does channel hopping (it's supposed to detect the in use frequencies though) if the game controller is old (pre BT3) it might disable some functions that allow BT to Coexist with wifi on the 2Ghz band, I did a quick test with my BT music receiver (BT 4.0) and switched to my 2Ghz wifi AP I didn't notice any interference, I'll test my ps3 controller later when I get back home to see how that functions.
BTW I suggest keeping it on 5Ghz if you have an 802.11AC router since you can get a link rate up to 433Mbps , N networks only connect at 150Mbps with this tablet .

Wifi cuts out when bluetooth is in use

Whenever I have both bluetooth enabled (and paired with any device) and wifi enabled, and I'm streaming music (Spotify in my case), after several minutes (almost randomly), the internet will stop working. Meaning, the WiFi icon will still show as connected, but it can't connect to anything online. I typically have to disable and re-enable WiFi for it to work, but then it would do the same thing again.
The strange thing is, my Galaxy S4 had the exact same issue/behavior. On both devices, I've seen this behavior regardless of the type of WiFi connection and/or bluetooth device (I've noticed it with my skullcandy headphones as well as my Sync in my car).
Do these devices share the same bluetooth/wireless chipset? Is it an Android thing? I'm forced to either use 4G with bluetooth, or WiFi with wired headphones. Thanks.
EDIT: this is using 5ghz Wifi.

What version of android are you on ?
carrier phone or unlocked. Some times these issues are carrier specific and non existent on others.
If you go into settings - wifi
Uncheck any option that says switch to data if wifi is unavailable.

I can confirm that this is an issue, I experience the same problem on my g4 818p

WiFi goes on 2.4ghz or 5ghz(most commonly on 2.4ghz) Bluetooth works on 2.4ghz. Unless you are 1m from router, BT is going to butcher your wlan. Had the same problem before. Solved it by buying dual band modem-router.
You could forcing different channel in wlan settings.

http://smallbusiness.chron.com/fix-bluetooth-wifi-interference-71008.html
idea here is reducing interference to bluetooth from competing sources.
- switch off wifi and use data which the OP is doing. Curious that the problems occur even at 5Ghz. Would have thought that band would be relatively immune to 2.4ghz sources.
- reduce the distance between bluetooth device and phone.
- move away from any sources of wifi interference if wanting to use bluetooth.
And now from the ppposite direction. Preventing bluetooth from interfering with wifi

Read the comments below. similar to the OP.
The key is more management of the problem rather than solution.

I'm using the Verizon variant.

this issue hunted me on all software version
Many options live
Router: Try another chanel
Router: Try only 2.4 or 5 Ghz
Router: Try only N or try only b/g/n mixed
App: Delete tunin radio
Last options send back service mainboard change.

i m facing the same problem but only when i do cellular call,
i am using realme wireless earphone , when i used to call my wifi speed gradually decrease , and after that stop working completely..,
after disconnecting the call i need to OFF and ON to work wifi again....,

My wife got the same issue with a Samsung A40 (and before with a Motorola), when using 2.4 wifi and Bluetooth connections (band and speaker for instance) the wifi is hanging. With wifi 5 it's ok. I don't have any issue with my phone using same network. It's crazy.

WiFi Disconnecting Issue

Hi,
I'm on my second P2XL (Panda). Both have had issues where they constantly and apparently disconnect on Wifi.
I have a Virgin Media superhub 3 (tried turning 5ghz off), also a TP link range extender plug. Seems to happen on both devices, it disconnects when I'm right on top of the Superhub router.
Any suggestions?
Thinking it must be the router, any suggestions?
would it be worth renaming either the 2 or 5ghz ssid?
I am a wifi newb and have the hub set on factory settings.

I think you are correct on the issue being with the router, and since the repeater gets its signal from the router the repeater is likely not to blame. Changing the SSID would not help. I would first ensure your router (and repeater) is up to date with the latest firmware. My Netgear router comes out with new firmware 2-3 times per year fixing bugs. TP link offers new firmware but not very often. Another solution may be to change the channel the Wi-Fi is using. Usually set to auto, you can change both the 2.4 and 5 Ghz band channels. It could be interference from your neighbors is causing an issue. There are several Wi-Fi apps you can use to find the least congested channels in your home. WiFi Analyzer is one.
If your router is up to date and still causing problems on different channels, you should consider replacing it with a well supported model. No doubt you have used your phone on other Wi-Fi AP's and not had a problem. If you've tried the above with no success, do some research HERE to find a new router.

FIXED - For me, my router was pumping 2.4 & 5 ghz as same name. I renamed the 5 ghz, forgot connection on phone and connected to the "new" 5ghz.
No drops since.
Think the phone was getting confused when it was at the far reaches of the 5ghz connection.

WiFi not connecting clean?

How can I test my WiFi connection to see how clean it is? I don't mean how strong it is... it's strong as heck thanks to the app WiFi Analyzer.
Plus, I'm literally two feet from the WiFi router.
But ever since I switched from cable to fiber Internet, my cellphone has had WiFi issues. Not sure if Fiber is the reason but it was around that time.
I've configured the WiFi router for bridged-mode and am using my old WiFi router that worked great with my phone.
I've tried stock Android, Dirty Unicorns and Ressurection Remix and all three have the same issue even though I'm doing a full-format in between ROM.
Like, connecting to Messages for Web (Google Messages) on my PC, it refuses to authenticate with my phone if I'm on WiFI. But the moment I switch to Cellular, Messages for Web picks up my phone right away.
And Pandora will time out if I'm on WiFi. But if I switch to Cellular, it connects right away. And sometimes after switching back to WiFi it will keep playing.
But speed test apps are all getting me low ms ping and blazing fast download speeds on WiFi.
EDIT NEVERMIND
Hahah, I just realized there was a thin metal plate resting on top of the test WiFi router I implemented.
The metal plate was severely much of the WiFi signal. I never noticed it because the WiFi router was above eye level.
So, the AT&T Fiber WiFi router sucked but the test WiFi router is working fine after I removed the metal plate that someone left sitting on top of it.

I have similar issue, but not consistent. Wifi is connected, everything seems fine, but sometimes it stops responding as if wifi is connected but no internet. As I switch off wifi internet starts working immediately or I have to wait a few seconds and refresh whatever I was using(browser, whatsapp etc).
Like you I am using fiber and to make sure if it is router based, I switched from crappy Huawei to a bit better Xiaomi router. But issue still there.
But there is some improvement if I select a relatively empty channel on 2.4ghz or 5ghz(neighbors dose not know about 5ghz too much). 2.4Ghz there is always problem but 5Ghz seems better(range sucks yes) and I think problem is based on channels.
I switched to fiber long ago and cable was more smoother but cable modem or router was quality, here ISP's are using very bad routers based on low end Huawei or TP-Link.
