It sounds like you have a cable connection, and the first person's PC is then
given access and an IP address, but any second or other person cannot make use
of the connection. I think you need to look for a 'broadband router' which is
able to let you * share * the connection properly. It should use a facility
called NAT (Network Address Translation) - the router will be given an IP
address by your internet company (not the first PC to connect) and then
it will allow any PCs on your LAN access.
What happens is that the on the WAN (wide area network) side the router will
get an IP address and some other (DNS) info from your internet company, and
then for the LAN (local area network) side, the router should have DHCP on,
so it will give out IP addresses for each of your PCs, when they are first
switched on, and will pass on some info so they call it when you want some
website or other internet service. It passes the request out to your ISP
and when data comes back, it knows which PC made each request and sends
back to the correct PC. If you look at the bottom of the diagram on
<http://www.dslrouters.com/Definitions/nat.htm> then you will see how a
router (in that case connected to a DSL service, but the idea is similar)
with a WAN address of 209.220.62.49 offers connections for PCs which have
IP addresses of 10.10.10.x (they are shown below as .2 .3 .4 .5)
On my network, I have a router set up with a LAN address of 10.0.0.100
and then my PCs are 10.0.0.111, .112, .113 in one room, .121, .122, .123
in another room, and so on. You could have lots more than 4 PCs - so long
as each gets a unique IP address (either from manual settings, or via DHCP).
