I have this Linksys EtherFast Cable/DSL router. MOdel number BEFSR41. IT has a switch built in. Is there anyway just to use the switch and not use the router part, because I have a router downstairs and this one won't work with that router (that's a WRT54G router - linksys). So basically is it possible to make this router as a switch? OR Can I have 2 routers on the network? I'm confusing myself..
