WiFi very slow when using Magic Mouse

I am having issues with WiFi connection since I started using Magic Mouse. I'm using a 15" MacBook Retina mid 2012 with El Capitan 10.11.2. The connection is much slower on the MacBook than any other devices when I run speed tests. Ping to external websites is around 300ms instead of 10ms which I am getting on other devices. Also download/upload speed is lower on the MacBook. Sometimes things are so bad that I cannot establish a connection to remote hosts and things go in timeout (e.g. http, Skype, and other protocols and ports).
See screenshot below where ping to google.com seems to be ok until the moment when I switch the Magic Mouse on.

Switching the mouse off, and/or the bluetooth on the MacBook seems to fix things.

I've read elsewhere that it's recommended to change the frequency which the router operates from 2.4 GHz to 5 GHz. However this is not an option for me as I don't control the network infrastructure of the different places where I use the MacBook.

Are there any other fixes for this issue?

MacBook Pro with Retina display, OS X El Capitan (10.11.2)

Hello apphancer,
Sorry to hear about your issues with slow Wi-Fi on your Mac. Let's see what you can do to get it sorted out.
I know you don't have access to change a lot of things on the router end, but take a look at the article below to run Wireless Diagnostics. This will scan your setup and then give you some suggestions to take depending on what it finds.
