I have one of those D-Link DAP-1522's and my father has two of them on my recommendation. A few thoughts:

- It works great at 2.4GHz. It works like ass at 5GHz. Set it to 2.4GHz and be happy with it.

- You can have the same SSID as your main base station. So long as you've got the same WEP/WPA configuration, you'll be able to seamlessly roam.

- After a while, my DAP-1522's wireless started to flake out. I'm currently using it with the wireless turned off as a generic switch. Conversely, with other routers I've had, the hard ports have died while the wireless kept on going. Suffice to say that adequate cooling, and apparently vertical mounting so you get a "chimney effect" to channel the heat out, is important.

- The cool part of a DAP-1522 is the switch on the back, which can toggle it between AP mode and bridge mode. There was a time when we were doing some construction downstairs and had relocated bits of the home theater into our bedroom. You flip it from AP to bridge, and now everything you plug into it is back on your network.

What makes me sad is that they haven't updated this box since it was released two years ago. The world needs a "simultaneous dual band" version of this thing. Also nice would be more than four ports on the switch.
