Switches or hubs?

By Whatme? ·
This may sound simple or stupid but... I have a network in a building w/3 floors. Each floor has approx 50 users. Server is W2k. I installed a home switch, ran cat5 to each floor where I installed a hub for each. All floors are on same subnet. Problem is... Each floor can't see the other floors. Is this a problem in switches? The on;y way around my solution was to install a "hub" at the server to service the other hubs. I know this isn't practable but it works. The switch didn't. How can I correct this problem and renistall my switch?
Thanks
Merv

Are you working in a domain enviroment or a work group enviroment? If is is a work group which it should not be but if it is you want to make sure that they are part of the same workgroup. Do all the PCs have static IPs or do they use DHCP? What type of switches are you using (Manufactuer)

Would like the answer to the questions from the first answer. Some more variables in your design:

You said that the floors can't see each other, , can the pc's on the same floor see each other? Can they see or Ping the server?

Look carefully at the cable connections to your switch and make sure they are correctly installed and that the cable running from the hub is from the correct "port" on the hub.

Good luck

This is how a switch works. It is designed not to pass through all communications to all ports. When you say you have a cable running to each floor, what the switch is doing is segregating each of its ports so that traffic from one port does not needlessly go through to the other ports. It does this to prevent too much traffic from going where it isn't required. Since most of the communication on one floor stays there, the switch stops the other floors from seeing this traffic unless it is addressed to an address on the other floors.
Good luck!

To answer the first 2 answers. Yes, I am on a domain. Yes, DHCP, DNS etc.
Thanks for your answer. Maybe the best way is to subnet each floor and run static routes to each after the switch is installed....?
