what is the cause for "Late collision Error" on my router

Hello!

My organization has a LAN which has more than 50 hosts. We have internet connection which is 128Kb/sec. The speed is now very slow on all hosts except the server. when I see the router configuration, there is a message which is "Late collision error" apearing continiously  .   What is the cause for this error? What do I do to imrove the browsing speed?

With 50 hosts (hosts? do you mean nodes?) you are probably overextending your network in one of several ways. Too many systems trying to transmit data at the same time created repeated collisions will eventually, after 16 trys i think, create a late collision error. if you are getting alot of those then your network is bogged down, check your cable length, check your cable specification - if there is too much wire between repeaters then collisions will occur in higher numbers. If the cable is not of the right grade, if you are running the cable near ofr over flourescent lighting and around machinery which generates high magnetic fields, collision rates will increase. Then again if you have 50 actual hosts and each is busy replying to many requests on a 128kbs pipe, then collisions are likely to occur anyway.

Also look for too many repeaters between nodes, (2 should be the max) or too many transceivers chained together.
