Q: Bluetooth Interfering with Wi-Fi?

Hello,

 

When I installed Yosemite onto my MBP, I was experiencing unbearably slow wi-fi speeds. At a certain point it would drop altogether. Then I noticed that I was attempting to listen to music on my bluetooth speaker the whole time. As soon as disconnected from bluetooth (Turned Off Bluetooth), my Wi-Fi connection would miraculously work again, allowing me to browse the internet and receive messages. When I turned bluetooth back on and paired my wireless speaker, the wi-fi connection would drop again. I did this a couple of times to make sure it wasn't a coincidence.

 

My Bluetooth signal is clearly interfering with my Wi-Fi connection–it was not doing this before the Yosemite update, so it probably isn't a hardware issue? Do I report this to Apple? Call customer support? Or is there some kind of fix I can work on myself? Any insight would be greatly appreciated. Thank you.

MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10)

    Whilst it doesn't solve your issue. I have no issues with a macbook pro retina, on yosemite, with a apple wireless keyboard and mouse and a JBL onBeat Venue LT bluetooth speaker all hooked up.

     

    My WiFi is a little slower with them hooked up but nothing major. My performance actually is better with Yosemite, by around 10Mbps. I now get 30 to 35Mbps (around 3.5 Mb/s on a torrent) on 2.4Ghz with Yosemite vs 25Mbps with Mavericks (with all bluetooth devices connected). I have a 40Mbps Sky Fibre connection for reference.

     

    Without them connected I get a consistent 36Mbps (around 3.7Mb/s on a torrent) without it going down ever. So I do lose a couple of Mbps.

     

    5Ghz is always full speed.

     

    It certainly isn't something that affects every single person on Yosemite who uses bluetooth and WiFi.

    Well, perhaps it's a "magic" trackpad issue...

    I don't believe it's a Yosemite issue. I'm having the exact same problems on Maverics 10.9.5. When I'm connected via Bluethooth to my Marshall Stanmore speaker, wifi slows down to a crawl.

     

    I couldn't figure out why, I thought it was because of my broadband provider. Didn't even enter my mind it was due to my Apple hardware/software. Not being able to use Bluethooth and Wifi at the same time in the year 2015 just seemed too surreal to be true. But evidently it is. 

     

    You think using an external usb Bluetooth adapter can solve it? Instead of using the MacBook's internal Bluetooth, I mean?

     

    This whole thing is not an issue when I use a Windows machine, so I'm not understanding why some people are saying it's "not an Apple issue".

    Unfortunately I have the exact same problem.

    Yosemite 10.10.2

    Macbook Pro (Retina, 15-inch, Early 2013)

     

    I have had this problem since buying a JBL OnBeat Venue LT.... I already thought it was weird that their was only interference in the music when on my MacBook.. and not when on my iPhone... Today I made the connection between the bluetooth speaker and my WiFi connection that had been very slow lately..

     

    I get the same difference in speed when bluetooth is turned on/off....

     

    Still no solution?

    A few days ago, I finally bought a Bluetooth dongle which helped resolve my problem as it doesn't interfere with WiFi (as opposed to my MacBook's internal Bluetooth chip).

    I might try that, but hopefully as a temporary solution.
    The WiFi - Bluetooth interference might also explain why my iPhone has a hard time being a hotspot for my MacBook.. sometimes it connects...sometimes it won't, pretty much random. Most of the time it does not work.

    Deleting this file: /Library/Preferences/com.apple.Bluetooth.plist

    And then restarting worked out for me... but it lasted only for a few weeks max.

    Now it stopped working, I am planning on repeating this procedure later today.

    Hey people. Has anyone gotten to finding a solution to this? My connection drops (still connected to the network not to the internet however) when my bluetooth is switched on, since I upgraded to 10.10.3. I am working on a brand new MBP and I kinda need both my bluetooth mouse and an internet connection to make my living. Like, literally. So one of the two will just not do. Also, the fact that I will have to get a new router to have a 5ghz connection is not a solution, because I being on a laptop I cannot really have control of all the places I go to connect to.

     

    I know that Apple does not reply, or even see these posts, but hey, if anyone can provide a solution that would be really awesome.

     

    Thanks.

    Hello everyone, I too have such problems! With Magic Mouse active connection is very slow, if it is disabled the connection is fast, but the wifi and bluetooth are always active, the problem occurs when I connect the Magic Mouse and I am away from my router, but if you have enough close I have no problem! You too have the same problem? I have a MacBook Pro Retina 13 "mid-2014.

    Just bought a brand new (early 2015) 13" Macbook Pro Retina - and am getting the same issue - a massive difference between wifi speeds with bluetooth on and off.

    Are you on 10.10.3 ? Or 10.10.2 ? What wireless router are you using ?

    To me it happens when I connect the magic mouse, and if I use wifi + bluetooth (without magic mouse) all ok! To you the magic happens with or without a mouse?

    Io sto utilizzando 10.10.3, ho un router NETGEAR, ma la stessa situzione si verifica con un router TP-LINK.

    So i gues we all have to  buy apples latest router wich

    operates on a different wavelength?

    If so than this is a real cheap trick of apple to use  the same frequencies 2.4 ghz both in bluetooth and wifi in yosemite.

     

    Now all yosemite adaptors are forced to change their airports as well to the newest available using both frequencies 2.4 and 5 ghz signals!

     

    Only then this problem will be solved. Using Yosemite altogether with the older version of airport will cause trouble either way.
