Troubleshooting Hub Connections

  For a network to function properly the several parts that make up a network must each work correctly. This includes the network adapters, cables, connectors, switches, hubs, routers, etc. Network software also needs to be setup correctly.

Here weŽll talk just about some hardware aspects of a hub. A hub and a switch have practically the same function. Switches have replaced hubs, so if finding good troubleshooting for a hub is hard, try doing a search for an Ethernet switch- the information can easily be applied to a hub.

The speed of your network will only operate as fast as your slowest component if you have a 10/100 Megabit per second hub. If you have an old computer with a 10 Megabit per second (Mbps) network adapter consider upgrading to a 100 Mbps network adapter.

The length of the network cable will also play a role in the speed of a network. The maximum length for a RJ-45 cable for a 10 or 100 Mbps network is 328 feet. The length of cable between two 10/100 Mbps routers needs to be 15 feet or shorter.

How your network cables are positioned may also be a problem. Make sure your network cables arenŽt coiled or bound together. Electromagnetic fields that often disrupt the data transfer between the two Ethernet ports may be created.

Also pay attention to where your Ethernet cables are routed. Try to avoid placing cables near power outlets, lights, or power supplies. These items may create electromagnetic interference between the Ethernet ports as well.

Make sure the connections at the Ethernet ports line up. Pins 1, 2, 3, and 6 need to line up exactly or you may have connectivity issues. Use a CAT5 cable to get the best results.

If you want to use any more than 2 10/100 Mbps hubs youŽll need to use switches. Use the uplink connector to connect the two hubs together. You need to use a crossed over network cable if there is no uplink port.
