I'm setting up an AirPort Extreme (5th gen.) for the first time. It's going well, but I'd like to give unique names to the 2.4GHz and 5GHz wireless networks that the AirPort Extreme broadcasts. The default -- and possibly only option? -- seems to be to have just one name for both. Maybe that's by design. Can anyone advise how to do this? Most router setup routines let you choose different names to use on the two bands. I've done the initial setup using a Windows machine and the AirPort Utility for Windows. I can redo the setup with a Mac, though. Thanks.
