Those are some unhelpful replies :-(

I don't have a solution but I think the problem is interesting.

Both Bluetooth and 11n share the same frequency band near 2.4 GHz so it
is possible that they could conflict.  If you had two laptops, and you
ran just Bluetooth on one and just 11n on the other, would they
both have problems?  This would tell as whether it was something inside
the kernel or if it was really wireless interference.
