I just had the experience of upgrading a 3850 switch stack. This type of switch has a USB interface which allows for easy(read: faster!) file copying.
This is how to set up a Cisco 2702I AP in Autonomous mode. The 2702i AP (and others) have two radios, namely Dot11Radio0 and Dot11Radio1, where the former is 2.4 GHz radio and the latter is 5 GHz.
When preparing switches or Labbing, I’ve often found myself searching for configuration examples on configuring DHCP servers on Cisco IOS switches.
