I have this ADSL router http://www.zyxel.com/web/product_family_detail.php?PC1indexflag=20040812093058&CategoryGroupNo=AC5783AE-9475-41AD-BDA5-0997187F44AA
and I want to connect it on my ISPs modem, so that I can have wireless connectivity.
The problem is that the WAN port on this router is an RJ11 port, and from my ISPs modem I can only have RJ45 (Ethernet) output. I understand that this router is mean to replace the ISPs modem, but unfortunately I cannot do that.
So in order to use the wireless functionality of this router I must find a way to connect to my ISPs modem.
Is there a way to do that?
