I have a cable modem, that connects to a linksys router that I got through Vonage. It has 3 ethernet ports and 2 phone jacks. I just got a laptop and now want wireless internet, so I got a neatgear wireless router. I'm a newbie when it comes to this stuff so I had a friend come over to help me set it up. He was having problems getting the routers to work daisy chained and suggested just getting a hub for the wireless internet. I called a few computer stores today and they said a hub is the same as a router?!? It will still have an IP address and DHC... this is where I get lost. Anyways, I thought the hub would just act as an extension of the router, therefore I wouldn't need to configure how the hub and router would work together... you can see I'm confused, any help is appreciated.
