I am just about ready to buy a wireless router, and some that I am interested in are ethernet connected. My Motorola Surfboard cable modem is also connected by an ethernet cable. I only have one ethernet jack on my computer. Can they co-exist? Does the modem plug into the router? I'm really not sure how all this works. Any helpful info for a novice like me would be much appreciated.
