I have a T1 coming into our building for internet access for the network. The T1 comes in via fiber, goes through a converter thingy, then to a CSU/DSU, then Cisco router, then into a hub, then to our NT proxy 2 server. The reason for the hub is that there are a couple other machines that require a direct connection to the network (eg - unreal tournament server, hotline server, etc...). There are about 5 machines plugged into this hub.

The problem I've noticed is that during periods of peak usage, there are quite a few collisions on that hub. I'm wondering if replacing that hub with a switch would make those collisions go away. Large amounts of collisions on that interface (T1) can't be good for bandwidth.

Any suggestions???
