Network, network, where is thy speed?

March 28, 2008 by Isaac

In the lab today I was having problems with a slow network.  In tracing the cables from the computer I found they went into a hub, not a switch.  After recovering from shock I checked the card settings to see what duplex mode they were in.  It turns out that in addition to being connected to a hub they were also running in half duplex mode.  This is a very busy network and a with a hub all the computers see the traffic from all the other computers.  A switch would be much better.  So on my todo list goes another task: get a switch from IT for this subnet.

Linux LAN card: Find out full duplex / half speed or mode
