Default [Q] Bluetooth interfering with Wifi?

Just got my HD+ and installed CM 10.2.1 One of the things I noticed is that when I'm connected to Bluetooth speaker, WiFi seems to slow down.
Watching Netflix or YouTube would frequently stop and start buffering; even when it's playing, Netflix picture quality drops as if I'm on a slow network. As soon as I disconnect Bluetooth, everything starts working normal again. Is this a known issue? Thanks
