I've got the 8" version and I noticed that when I connect a bluetooth headphone or speaker the wifi slow down to less than 1 mbps while playing music or video. Can anyone test if it's a common problem or is it just my unit?

Thanks.

PD: sorry for my english if I made any mistakes.

I don't own the MediaPad M5, but i have a MediaPad M3, and it does indeed have the same problem. I was wondering about getting an M5, but if it have the same problem, i am a little skeptical.

Well as WiFi and Bluetooth use the same frequencies there is always an interference between them especially if you have two streams in parallel (downloading the music file and transmitting to the head phones). You could try to use 5GHz for WiFi in that case Bluetooth should not be affected.

This isn't a minor interference, it makes wifi almost useless. Less than 1 mbps of download speed, latency increases and sometimes it doesn't even work at all. I did this speed test right next to the router while playing a song:

With bluetooth on it is impossible to stream a video without constantly buffering. I did the same test on my phone and my laptop and both are ok. My router doesn't support 5 GHz, but I read that it doesn't fix the problem for people with the same issue on other devices.

Edit: And don't forget that this tablet doesn't have a 3.5 mm headphone jack (a really stupid decision if you ask me), so it push you to go wireless and this is what you get.........

I have the m5 10" version and I have the same. About 0.5MB at a 5Ghz network while listening to some music. Get around 5-10MB with Bluetooth disabled.

It's not just my unit then, must be a bad design of the antennas or whatever I guess, great. Because I don't think it could be fixed with a software update, right?

This is unacceptable to me, I'm going to return it. Now the problem is what tablet buy next. What other choices are there? IPad, I don't like Apple; Samsung Tab S2 is kinda old; S3 too expensive...... damn it.

I have the M3 and just tried it. With Bluetooth on I get less than 1 mbps down while streaming, just under 5 mbps with no streaming. With Bluetooth off I get 155 down on my 5ghz wifi. Damn. I usually use my phone for music.

This is not device specific. This is a bluetooth WiFi general problem. The 2.4 GHz frequency

I appreciate that you're trying to help, but come on, don't write the first thing that comes to your mind without checking the facts....

Just do one Google search. I have 3 devices. Google nexus 10. Oneplus 3 and the mediapad m5. All have the same problem when using bluetooth devices in various routers in various network providers in various houses. This is a problem that thousands of People have asked all over Internet, in Android in ios in Windows Phone. Im not saying nothing that Comes out of my mind.google it before you call me out.

Ok, I'll give you some numbers.

M5 bluetooth off (I know, my internet connection sucks):

Nexus 5x playing a song through bluetooth:

Nexus 5x bluetooth off:

Can you see the difference??

I know that if a lot of devices are connected at the same frequencies there is going to be interferences and the speed is going to drop (notice the minor hit in the Nexus). But the case with the M5 is not normal, must be a bad design. It makes wifi almost useless. And there are 2 replies that have test it in a 5 GHz wifi and the problem persist.

Man. I gave up bluetooth headphones a long time ago. Just search the internets for this problem. You have enough to a week. The general answer for this question is change router channel or get a 5ghz router.

Again?? Did you not read that a 5 GHz router doesn't fix it? This thing is broken.

Give up bluetooth headphones on a device that doesn't have a 3.5 mm jack, great. And no, that stupid usb to jack adaptor it's not a proper solution to a problem that shouldn't even exist in the first place.

The tablet is going back to the store next week.

Again. Google it. Its not a problem related to this device. Its all over the internet. Every OS and lots of devices. Maybe some devices dont suffer as much from the problem but this is definitely not a problem related exclusively to this device.

Oneplus 5 just now. With Bluetooth device connected 124 down 12 up. With Bluetooth device connected and streaming 134 down 12 up.

---------- Post added at 06:39 PM ---------- Previous post was at 06:12 PM ----------

Oneplus 5 just now. With Bluetooth device connected 124 down 12 up. With Bluetooth device connected and streaming 134 down 12 up.
I just realized that I didn't test with no Bluetooth.

No Bluetooth - 160 down 12 up
Bluetooth device connected - 170 down 12 up
Bluetooth device connected and streaming - 168 down 12 up.

It looks like Bluetooth improves download speed. ?

Unbelievable..... Last time I reply to this.

I have tested my family's phones, a Xiaomi Redmi 3s and a Xiaomi Redmi 4 Pro, and both under the same conditions give me around 9 mb/s:
r6OJXwm.png


So let's compare numbers:
Nexus 5x - 12 mb/s
Both Xiaomi (budget phones) - around 9 mb/s
Huawei M5 - around 0.6 mb/s (tested multiple times, it never gets more than 0.8)

The M5 is more than 10 times slower. Do you get it now? Yes, none of them get the maximum speed when bluetooth is on, but only one becomes extremely slow.

Ok, those are the hard numbers, but what about real life usage? Well, the M5 is so slow that browsing the web is a pain in the ass, web pages with lots of images takes forever to load, and it is impossible to watch a hd youtube video because it's constantly buffering. None of this happens on the other devices. Do you see the problem now??

Oneplus 3 Just Now. With and without bluetooth device connected.

Well, I'm sorry for you, but your phone has a problem too. Maybe you should contact One Plus....

No Bluetooth - 160 down 12 up
Bluetooth device connected - 170 down 12 up
Bluetooth device connected and streaming - 168 down 12 up.

Thanks. A demonstration that it can be done right.

this is really sad to see. there are so few tablets to choose from, and even less if you want hd screens and latest gen hardware. this one looks great on paper, but reading in here is a complete disappointment.

it does not take a rocket scientist to notice the speed problem, and anyone that says "well dont use bluetooth!" if they cant make them play nice (which they do fine on other hardware, at least well enough to use both at the same time without noticing an issue) they should not have even put bluetooth on the device.

I hope ppl staying saying ALL android has this problem, the problem with my M3 is wifi is nearly unusable when blutooth is on. And pls stop misleading huawei tablet users 5ghz will be better. IT DOESNT HELP. I have owned many android ( samsung note3, note5, xiaomi, even entry lenovo tablet n nvr had one with wifi problem with blutooth on. I am using m3 and even 5ghz is below 1mbps for download with blutooth on. If u have sim version u should check from time to time.. It is slow extremely slow compared to other device using the same sim. I have given up. By the way my problem is only for download, upload tests are ok with wifi n sim.

    Maybe i found a solution...

    Had the same problems with the M5: WLAN (2.4G & 5G) works fine without bluetooth on. But after i turn on bluetooth, all streams had lag spikes. To info: I use my M5 mainly for game streaming (moonlight, steam link app). The steam link app has a fine tool for testing the network connectivity. In my case, with WLAN & bluetooth on i had a lot of spikes (ca. every second), not possible to play any game.

    But after i turned off the location service (GPS and WLAN), everything works nearly perfect. The steam link app didn't shows any spikes anymore. And the best: Streaming now working on 2.4G and 5G.

    Hope this helps one or the other.

    No problems on my M5 10.8“ with wifi speeds when connect to Bluetooth. My network is 5ghz.

    Weird. Others said both models have the problem. Were you playing some audio while you tested it? Because bluetooth has to be transmitting data to really notice the slow down. What speeds are you getting?

    I test the Twitch App on the Tablet. Without bluetooth no problems with a twitch videostream (not livestream). But with Bluetooth Headhone on the same twitch videostream (not livestream) i have laggs (loading circle), and the screen are blurred. The internet connection has issues when bluetooth are on to use the headphone on the tablet. But in the YouTube App i can see a 1080p without problems. No laggs, blurs or videoresulution changes, the Youtube App run perfect on 1080p with my bluetooth headphone. It's an App problem, i hope a softwareupdate can fix this problem. I change my network to 5Ghz no improvement on the Twitch App. When i turn off my Bluetooth Headphone in the Twitch App, all the problems are gone.

    It's not an app problem, it's a hardware issue. I tested it with YouTube and the buffering was constant. Maybe the video you tried has a low bitrate or whatever, make sure you are watching it in HD. Try different videos and you should see.
