It looks like they say they can.

It's a first, **if** it's a real working product instead of a reference design. Neither D-Link, Linksys, nor Netgear have such a product based on it or something of their own. Until a product hits the shelves, the argument is moot:
today you can't repeat Wireless-N. You
can repeat B/G, so buy a DWL-G800AP and change the wireless mode on the DIR-655 to B/G only and there's one solution.
You can bridge them. Connect an access point to a wireless client and you've essentially accomplished the same thing. Two DAP-1522, one as AP, one as wireless client, will likely accomplish exactly what the O.P. wants to do. (I haven't tried it.)
I want to understand what you're suggesting here, are you building a bridge link that goes:
DIR-655 <--Wireless--> DAP-1522 (Bridge Mode) <--Wired--> DAP-1522 (AP Mode) --> Wireless-N
It looks like it would work, adds about $200 more in equipment cost and it would get "close to" N speed. The best solution would be to run one wire to the other location and hook up another DIR-655 or DAP-1522 since they cost the same on newegg.
