I have a Cable Modem, and a hub that are connected correctly.

I am unclear on your network setup. If you connected the PCs to the hub and the hub to the cable modem, this setup will not work.
Only one PC will be able to connect to the internet (unless your ISP provides multiple IPs, but this is rare).
The two easiest ways to setup a home network are as follows:
Cable Modem -> Linux PC -> Hub -> other PCs
Or
Cable Modem -> Router -> Hub -> All other PCs
( In this example, the hub is optional -- depending on the type of router).
In the first case (where Linux acts as the router -- default gateway), you will need to setup IP Forwarding and Masquerading.
This is done using iptables.
