I'm hoping someone can help me with some home networking.  My apartment is
pre-wired with CAT5 cables.  There are 2 RJ45 connections in the living room
and one in each bedroom upstairs.  All 4 RJ45 have cables attached to them
that lead to the closet downstairs.  In the closet are 4 RJ45 connectors on
the opposite end of the cables.  In one of the bedrooms are 3 PCs and a
Cisco 675 DSL modem and there will be one PC downstairs.  I have 10 7' CAT5
cables, 1 8 port 10/100 dual speed, and 1 4 port 10baseT hub.  How can I
make this network work?  I tried simply putting the 4 port hub in the
closet, connecting it to the 4 RJ45 connections.  This works fine as long as
I don't introduce the 2nd hub, however this configuration only allows one of
the 4 nodes in the bedroom to be connected because there is only one jack in
the bedroom.  So I tried connecting the 8 port hub into the wall jack in the
bedroom and connecting the 4 nodes to it, but this rendered my network
useless.  The machine downstairs cannot see the DSL router or any of the
other PCs.  Can I not connect 2 hubs together like that?  If not, how do I
make my network work?  Do I need a switch?  A router?
