I would like to connect my DIR-615 (version B) to a 4-port switch/hub using a cable. Do I need (i) a patch cable or (ii) a crossover cable to connect the DIR-615 to the switch/hub? Also, the cable will be 100 feet going through walls. Will CAT 5e work, or should I step up to CAT 6 or even CAT 6a? Thanks.
