Hi, I don't really know a whole lot about networking, so I am hoping to learn a little. I currenty have a WRT54G router that connect to a cable modem. There are 4 computers (all on XP) connected to the router with WMP54G cards. I have two more computers on Windows 98 that I would like to connect wirelessly but, the router only has 4 ports. Does this mean you cannot connect more than 4 computer to the router? If so, what do I need to get so I connect the other computers? Otherwise, can I just buy two more of the WMP54G cards and connect them to my current router?
