Perhaps you have heard of the term "Ethernet," but don't know exactly what it is. To put it simply, Ethernet is a networking technology primarily used to connect computers to cabled networks. An example would be the average network that consists of two or more computers. In this scenario, each machine uses a CAT5 cable to connect to an NIC (Network Interface Card) and uses Ethernet to interact with each other. Aside from computers, Ethernet technology can be used to connect devices, such as a printer or cable modem to a network.
Understanding Your Ethernet Device
Most new computers come integrated with either an Ethernet or NIC card. You have probably observed one on your machine, as it looks quite similar to telephone jack, only larger. These network adapters are widely used among personal users due to the popularity of broadband internet access and home-based networking. Even if there is no Ethernet port on your computer, installing a network card is a relatively easy process. However, it does call for you to physically open your computer and install the card. If this is something you don't feel comfortable performing, a local computer technician should be able to handle the job for a reasonable price.
Helping Windows Communicate with Your Network Card
Regardless of who installs the network card, it is important to know that the device might need a little help before it can be networked with other computers and devices. In most cases, you will need to install a device driver so the operating system can recognize the card and understand how to use it. Although the Windows operating system will automatically detect some installations, others require that you manually install the appropriate device drivers. These drivers should be included on the disc that came with your Ethernet device. Simply insert the disc into your CD drive and follow the prompts on the display to install the drivers.
What if Your Ethernet Card Stops Working?
Just like other components, Ethernet cards occasionally stop working properly. You can generally tell there is a problem if you can't make a connection to the internet or your local area network. If other computers in the network can make a connection, but you cannot, it normally means that your Ethernet card is experiencing problems.
Before rushing to buy a new card, make sure the cable is firmly plugged into the jack. If so, the problem can often be solved by simply updating the Ethernet device driver. A device driver can stop working for a number of reasons, including corrupt files or the installation of new software or hardware devices. Fortunately, updating a driver is very easy.
How to Update a New Ethernet Driver
To install new drivers for your Ethernet card, open the "Control Panel" and click on "Device Manager." In this window, locate "Network Adapters" and click it to expand the category. If there is truly a problem with your network card, there will be a yellow marking beside it. Double-click the device in question, click the "Driver" tab and choose "Update Driver." Next, click on the option that allows you to automatically search the internet for updated drivers. If device drivers are found online, follow the given prompts and install them on your system.
