When I initially went with cable modem service, the provider told me I ABSOLUTELY had to have a second IP address for my second computer to have Internet access. Since that time I have purchased my own modem (Toshiba PCX1100U) and Linksys 5 port Workgroup hub in order to network my two computers. I've become a "little" more IT savvy and now believe I don't actually need a second IP address, but really just a router (instead of a hub)...? Or do I not even need a router? Can I save $7.00 a month (second IP address charge) by just using the hub or router? The service provider "warns" me that if I cancel the second IP address, the second computer may not be able to access the Internet since the provider has now switched to static IP addresses for all users. What is the truth? (I have read previous, related responses of knel1234, pbessman, and stryjews -- impressive interchange, but I'm still confused.) Thanks.
