Is there a way of configuring an Airport Extreme base station to only use 802.11n and not automatically downgrade to 802.11b/g? Or even better to set one of the dual-band networks to use n and the other to use b/g? I have various WiFi devices at home some of which are compatible with 802.11n and some which are only b/g. It would be great if there was some way of allowing the faster devices to use the n network and the slower ones the b/g network. (Oh and to make things more complex, only 1 of the n devices that I have can use the 5GHz band, all the other n devices use the 2.4GHz band - can the Airport Extreme be set up to have both a b/g network and an n network on 2.4GHz?) If anyone has any ideas, that would be great!
