Networking over hub

I have a 16 port hub connected via uplink port to a 3600 series Cisco switch. The end users are experiencing slow transactions and when I set up continuous pings to the router I would loose ping packets intermitently. There are about 13 connections connected to the hub which connects to a 10/100 TX switch port. Any ideas? I thought splitting users off hub onto a second hub would help but what is the point of a hub if I can't utilize all the ports? Thanks

My guess is that things are slow simply because of what a hub does. Once a hub receives a packet, it will send that packet to every node on the hub. With a switch, it has the ability to read the header information and send the packet straight through to the correct destination. Your packets are probably being lost due to collision, which is much more common on a hub than a switch. If you are looking for blazing network speed, you need a fully switched network.

First, a 3600 Series Cisco is a Router, not a switch.
Now if i were u, i would get into the router and look at the port stats of the ethernet port. Do some commands like "show interfaces stats" or "show int e0" or "fa0". This will give ayou a goodindication of what's going on. You should not be losing packets unless you have an extremem amount of traffic, or unless there is a physical cabling/NIC problem. You hub, if it has lights like for utilization or collision lights can also be useful. Splitting off the users will not help.

If you find that the network is just normally busy, then consider investing in a 10/100mb switch.
