RJ11 is for telephone and use telephone cables.
RJ45 is for ethernet and use Cat5/5E/6 cables.

They are not compatible with each other.

Why do you want to do this?

The nearest thing to a converter would be a DSL modem...

Wait, so WHY do you want a converter then?
The DSL modem should have an RJ11 input where the telephone line goes into??

So u have a DLS modem and want to share the connection with ur house network ?

If yes then it's simple. RJ11 phone cable goes into the DLS modem and RJ45will come out of the modem which u need to connect to ur router to share the connection. U have to do the proper setting in ur router though, so that it can do the proper dial up with username and password.

If no, let us know clearly what is ur intention for the need to convert.

Ah ok so you DON'T need a router, you need an RJ45 switch/hub so you can connect more computers to that RJ45 line you have.

You need a completely new router that takes ethernet for wan. Your current router only does DSL which is why it has rj11. It is not a cable issue even if the port in the router were rj45 it will not work.

If it were that simple why could you not do the reverse...plug your PC directly into the phone line with a simple cable converter instead of buying a expensive modem.

It is not a wiring problem DSL and ethernet are totally different things.
