Is there Anyway to fix slow wifi on rMBP without changing wifi or changing from magic mouse. The wifi is useable however it is slowed down with interference from the bluetooth card with is apparently too close to the wifi card. I haven't been able to find a solution with the only one being don't use bluetooth or get a 5GHz router. Is this still the case? Is it worth phoning apple and asking why the magic mouse is slowing down my wifi speed?
