Just got the AEBS Dual-Band; all happy to configure. Everything is just like the older version, except with the addition of the MobileMe, Guess Network, and jolly-jolly simultaneous dual band! Well it's not as good as I was expecting. On my Linksys WRT600N I can set a WPA/2 passphrase for each network, have seprate names, choose what mode to use (N-only, Mixed, etc.). This is not even close! It only lets me choose different names, but I have to use the same passphrase for both networks, I can't force one to be N-only or whatever. It's not jolly-jolly at all and a big waste of my money. EDIT: If you change the Internet Setting from sharing a public IP to something else, you lose the ability to create a guest network. Indicated in post #12. In other words, if you this is just going to be an AP for your network and/or you have another device acting as the DHCP server, you lose the functionality. Oh when I forced a different name for my 5GHz network, I lost the ability to create guest network.
