does anyone know what 802.11n is backward compatible with? I have read articles saying that 802.11n will be compatible with all 802.11a/b/g because it runs on both the 2.4GHz and 5GHz band. But recently Ive read that the 802.11n draft using 20/40 MHz BSS mode is compatible with 802.11a but no info on 802.11b/g. &nbsp;does anyone have more info on 802.11n draft 2.0 and the upcoming 3.0? and what the current draft and finale 802.11n will be backward compatible to?
