Networking with Telephone lines and cards

I purchased 2 cards for Networking using a host computer, and a second card in the other computer. The system is on cable modem, and the main computer does fine, however the 2nd computer won't go online.
Does anyone have any idea of what I should do? The telephone line runs frommain computer to wall, and from wall jack to 2nd computer. Thanks, Bill

 

you don't need any phone lines.
if the computers are networked with r45 cable, then the cable modem is host of the system, wire them thru a hub, then set each computer to get dns automatically.
each computer needs a diff name, both in the same workgroup.
