Apple to this day locks out 40 MHz bandwidth mode in 2.4 GHz entirely on its AirPort Extreme and other 802.11n routers and combo devices. Intel initially followed suit with its 802.11n Centrino wireless adapters, but has since relented. Intel adapters now allow 40 MHz mode in 2.4 GHz to be set, but ship default set to 20 MHz only mode.
