Well, yah, you will have to do some interaction to get your Internet going. Are you using USB or connecting to an Ethernet card?
If either are supported and its detected, you should be prompted during the install to either use DHCP or setup a Static IP setting. If you use DHCP, that should really pretty much do it as all the information is obtained from the ISP. If static, well then you will need to supply that information to connect.
