Plug the modem into the router and then plug the router into the switch (hub). Finally plug all your PC's into the switch using CAT 5 network cable . I don't use the RS232 cable because access to the router can be done via your web browse (see further down).
Installation and set up of the router is done via a web browser. I have to warn you that this is not for your average user and is very complicated. Computers use a language to communicate between one another called TCP/IP. You will need an understanding of this and the user manual assumes that you do.
Once you are connected to the router via the web browser you have to set it up. Type in all your ISP details such as username, password. Add your other PC's etc…The router set-up is very long and complicated. It took me hours to get everything working. The user manual is very complicated and basically if you don't understand the ins and outs of PC then its like reading a book in Chinese. I spent more time trying to understand the paragraph I had just read than actually doing what it was trying to tell me.
What I am trying to tell the possible user is, unless you really have the time and understanding of PC's, then I suggest you ask a local computer shop to come and install everything for you. If like me you are PC literate then the job is possible but can be frustrating at times.
