From what I can gather, your internet works if you are connecting directly to your modem. I don't know what internet service you are using. Some providers use the mac address of the adapter that it was originaly connected to.
You introduce the router, it has a different MAC address than the connection is looking for. Your router setup has what is called MAC cloning. This is where you change the MAC address of your router to match the MAC address of the adapter originaly set up by your internet service provider. Of course you are not physicaly changing your routers MAC address, it's a software fix that tricks your ISP into thinking it has connected to the original adapter. To make things simple your install CD that came with your router should do this for you.

Rogers Hign Speed (ISP):

Well, in the scenario when I have CAT 5 cable running from PC to router and rogers modem connected to router WAN via CAT 5. Wall socket connection is removed here. Have connection and internet
I feel the router, modem, and wall socket CAT 5 connections are all working. The modem was connected to one PC for many months now but the router was in the mix with no issue. I'm confussed. Should I proceed with running LinkSys Model: BEFSR41 Ver2 CD? Thanks.
