 RJ45 on the CableModem RJ11 on my router
Hello guys. I am having a problem with my connection here. You see, my ISP has supplied me with a box that has an RJ45 connector to connect to my PC.
I, on the other hand, have a router which has only a standard RJ11 for a WAN port. Is there any way to connect my cable modem and the router? This way i will use the DHCP option from my router to act as a NIC and issue an IP from the cable modem.

There are 6 cables in my RJ11 plug. As i have read, only #3 and #4 are used right? On the other hand my RJ45 uses two pairs to transmit data.
Wires #1,#2,#3 and #6 thats why i don't know what to connect.
Any ideas would be really appreciated.
Thank you

Dear Mike,

It sounds like your router is a DSL unit and the signals are different then an ethernet port. They cannot be connected directly to each other.
