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? Mike
