Yes.
Once you choose UniFi mode in the RT-N12HP setup, then it will act as a modem + router just like the DIR-615.
By the way, why are you upgrading to RT-N12HP?
DIR-615 & RT-N12HP doesn't have any discernible performance differences except for wireless strength.
The RT-N12HP doesn't even have a USB port.
If you really want to upgrade, you should go to for at least RT-N56U.
If you're looking for a router with external antennas, go for RT-N16, then you can change the antenna to anything you want.
the reason I choose this router is that I live in a 2 1/2 story home, and all of my notebook/iPhone/iPad are connected via Wifi. I only have a PC that connect using cable but that also hardly been use.
currently the Wifi signal is very weak at back of my home, the kitchen side and the back room.
I read quite a number of review regarding this router providing excellent Wifi signal which fit into my scenario.
thanks for the confirmation, will go scout around for this model and a few more Asus model.
