Hi All. I just purchased an AirPort Extreme Base Station today. I ran down and picked it up from Best Buy, with the understanding that I can set up a guest network. When I navigate to the Wireless tab within the AirPort Utility though, there is no option to set up a guest network. After some research, I understand this option may be hidden if the modem I am using is not compatible. I just want to make sure that this is the reason for this and I didn't buy an AirPort Extreme that had been sitting at Best Buy for years (old model). Does anyone know how to tell if I did purchase the latest edition of the AirPort Extreme? On the bottom sticker, it has the following: MD031LL/A Model No. A1408 I'm not sure if this means anything to anyone, but any help/advice would be much appreciated. Thanks!
