Need Some Help with Cable Modem to Gray Fox Router to Switch Router

I have no idea why but i can only get a connection with the internet with one computer through a switch router... i was told that its not possible to get internet to multple computers, and only to one computer. I have a Netgear Gs108 switch router... but it connects to a Gray fox router which runs through my walls which my modem is connected too. i have no idea how to get internet through all computers which i have been before, i just got cable modem and it this problem started. So before the problem it was DSL at&t. Mabey some can help me please..

Do a search( upper right box) for cable modem to Fox router to switch router.
