a lot of dorms use rj11 wall jacks so you may need an rj11 male to rj45 (standard "ethernet") adapter i havent been to the Roosevelt dorms so i dont know if this is what it is you specifically need but you can find these on amazon and you can use the free next day/2 day delivery to the amazon SBU lockers
