The Wireless N Network Adaptor for the Xbox 360 is on sale now. The old N-less adaptor is now $30 cheaper.
As we've mentioned, the new adaptor takes advantage of the 802.11n protocol to deliver, according to Microsoft, up to twice the range and seven times the speed of the older model adaptor.
It's $149.95. Microsoft will continue to sell the old adaptor, but it has been reduced to $119.95.
