All depends if the asus can act as a repeater. WDS is the hack they use to make repeaters work. The big question is does the asus actually act as a repeater or does it just support you connecting a repeater to the router. The home hub must also have WDS support. Most routers do but it is considered a security exposure so it many times is disabled.
Note even if get this to work it is not the optimum way to do this. You will likely lose at least 1/2 the bandwidth. Pretty much you only use a repeater when have any signal at all even a poor signal is better than not having any connectivity at all. If you can live with that it will be fine.
