The DIR-655 does not have any WDS capability like the AE/TimeCapsule, however...if you set the AE as the router instead, and then go into your Apple AirPort Utility, you can select "Participate in a WDS Network", you may be able to add the DIR-655, if you add the MAC address, and follow the steps listed here: http://support.apple.com/kb/HT2044
But as Lycan stated earlier, I also believe this will not work.
