Question : Share DSL internet

I am trying to setup a network to share my DSL internet connection between five computers with XP operating system. There is already a network using a hub to share data through computers. I tried to use one of them as a main pc and other's to be sub.
I added a network card to the main pc. First card is for main network and second card for sisco modem.
It works but the internet speed in very low, even less than dial-up!
Is there a better way to do this?

There is a better way - with a broadband router. Since you already have a hub a router will run you <$50. Super easy, virtually plug and play.
