Hello I registered in this forum to see if you can help me.

I maintain a TP Link router model w8961n, I would like to place 2 computers in that mode / router, which assigns 2 different IPs to 2 different computers, is there a way to do that?

They told me that with a swicht you can do that, but then they told me that this would be:

router + swich + moden
and not with moden / router + swich

could you help me? I would be grateful.
