You ' re right , I don ' t know the whole story , but OP ' s attempt to get everyone on his side instead of actually asking for advice is pretty transparent , and as others have noted it seems like they ' re not his pets , and we know it ' s not his money since she wanted to use her own , so it ' s really none of his business whether her reasoning for not wanting to patronize a business with terrible customer service is rational . <| sep |> im dying here cant stop laughing ! great story <| sep |> As far as I understand , Miracast uses a direct form of wifi connection . Wireless N and Bluetooth both use the same 2 . 4 GHz bands and are supposed to coexist peacefully , but in my experience with my 950 XL it ' s not always the case . When I ' m driving , I stream music over Bluetooth to my car stereo . If I have wifi turned on and drive by an access point strong enough to be seen by the phone on the street , the music stutters for a few seconds . If I turn wifi off , there is no issue with streaming . Personally , I think it ' s the new stack in W 10 M as my 920 and 1520 both had no problems with Bluetooth and wifi on at the same time in the car .
