Of course I had already installed them.
When I am just surfing the web with N connection, bluetooth works not too choppy. However, when the throughput gets high, then my bluetooth devices suddenly become choppy, making them unusuable.
I have heard that it is because this chip uses the same antenna for both bluetooth and wifi, which makes sense, because turning off HT mode and keeping the bandwidth/throughput low help the bluetooth devices to work.
But, that's unacceptable.
I hope you guys address the issue through driver updates ASAP. Otherwise, I will have to advise everyone I know with ultra portable devices not to buy anything that has Intel chip inside.
