Need help setting up web router
 

I've got a net gear rp114 web router (4 port switch) with 3 computers connected to it. I've gotten all 3 computer up on the web once, but after I restarted, the web no longer worked. Anyone worked with this router and its web setup, and run ito similar problems? If so, any help you could provide would be MUCh appreciated. I'm pulling my hair out here. Thanks!
