Component ProblemsYou Can't Get There from Here
Just as in a large corporate network, you might have a problem with one or more
For example, most network adapters have two LEDs you can examine. One is called the link LED and the other is used to
These same signal lights are also present on switches, including routers with integrated switches. Routers also have additional signal lights to indicate WAN traffic (traffic moving to and from the broadband cable or DSL modem) and diagnostic lights. See your router's documentation for details.
Another thing to think about is that many small hubs or switches have an "uplink" port that allows you to connect the device to another one when you want to expand your small LAN. The pinout for this port is not the same as it is for the other ports. The transmit and receive pins are swapped. If you need to plug a computer into an uplink port, you can usually do so, but there will probably be a small button or switch you need to use to change it from an uplink port to a standard port.
Secure Those Cables!
A common problem with small offices or home offices is that you are not using a structured wiring plan. That is, you just string cables from here to there and plug things in. If you have a twisted-pair network cable lying on the floor near your desk, use tie-wraps, scotch tape, or anything else that you can to make sure that the cable doesn't just lie on the floor where you can roll over it with a
If you can't hide your cables from
A friend of mine had a pet rabbit at home that was occasionally let out of the cage. Rabbits, in case you don't know, like to chew on just about anything (my friend no longer has the rabbit). Be sure to keep your network cables (not to mention electrical cords) safe, even from your pets!
If you suspect a problem with the cable, trace it from the network card back to the hub or switch/router to be sure that it hasn't been damaged. Never try to "stretch" a cable or pull too hard on it when you are moving things about. This too can damage the cable and cause it to generate so many errors that the network becomes unavailable to the attached computer.
If your service provider is using DSL, you might have to connect a small device to your telephone outlet known as a microfilter before you can plug in a telephone. This device
