I have the latest Airport Extreme that can broadcast at 2.4GHz and 5GHz. I read that devices can switch between the best network if both bands are turned on. How exactly does this work? My Net: 2.4GHz name - mynet 5.0GHz name - mynet 5GHz Devices: Setup with both networks. But it seems that it'll only connect to the last one entered in the settings. Thanks.
