text: dsl help !!!? if my dsl didnt come with a 4 port router is there a way to like get a addon to it or a way to split that connection onto 2 computers for no extra price? get a rj-45 cable plug #1 to your main computer get another cable. plug it in #2 port and to your second computer. make sure the rj-11 cable is still plugged in and you still have power. simple as 1-2-3.
