I have just installed a Motorola SURFboard SBG901 cable modem, and I can connect two computers I have to the Internet via Wifi. I'd like to distribute the Internet connection among some other machines through Ethernet instead, in an inexpensive way.
I've done some research on the Web, but I have found the answer for this in random forums, which seem to contradict each other. In one of them, I read that the simplest is a network switch, while in others I read that a switch will require me to maintain a central server, and then I should purchase a router instead. The Wikipedia articles on Network switch and Router have left my head spinning!
I have noticed that in the SURFboard there is no way to change the DNS servers, and it also doesn't seem to hold a DNS cache. Is it possible to have these without a central server?
Also, does a switch, hub, or router generally have some kind of bandwidth control?
The most important for me is to know what should I purchase just to share access via Ethernet with these machines. Regarding the DNS and bandwidth control, they would be desirable, but not a priority, so a small comparison between how a switch, hub, or a router would apply in my case would be highly appreciated.
