Apple's instructions do not work for me when I try to create a Guest Network.
Here is what happens: The "Set Up a Guest Network" instructions do not work. Step 3, "Click Wireless and then select Enable Guest Network" leads me to "Create a Wireless Network."
If I click on that, it leads me to create a substitute for my primary network, leaving me with no second option that I can designate for users. In other words, my "Guest Network" replaces my primary network. Something in both the Airport Express manual, and in Apple's online Support comments does not jibe with what the Utility is asking me to do.
