Anyone have the new Airport Extreme? I have a question about the new features. I'm interesting in picking one up because I've been looking for a good 802.11n router for awhile, and the simultaneous dual-band radios plus the guest networking feature are the real sellers for me. Both those features exist in part on other routers, but I'd have to put in a lot of work in a DD-WRT compatible router to get them both to work properly. My question, though, is can both the dual-band radios and the guest networking feature be run simultaneously? It seems that from a hardware perspective, the easiest way to get a second network and SSID running would be to use the second radio, which precludes the dual-band feature. Does anyone have the new Airport Extreme yet? Can you run both at the same time?
