I doubt it is possible. Consumer routers do not really know the difference between things that are coming in over wireless and things that are coming in over the lan. Then this router does not have the ability to limit to some fixed rate. It has all kind of packet marking option that are worthless on a internet connected router(the isp removes them all). All it can really do is favor certain traffic over others mostly based on a ip address. It also can only do this on UPLOAD traffic it does not even have basic feature to attempt to limit download rates.
