Setting a Home Network System

February 10th, 2010



A Home network system come in two basic types. These are cabled (or wired) or wireless. Whichever type home network system you opt for, you basically find out that they both will have some of the same types of equipment, although the specifics will differ between the two.

For any two parts of the network to talk to each other, there has to be a route between them. In a wired network, this is done by physical means – the cables (generally cat 5 or Ethernet cables). These cables come in lengths varying from a few feet to hundreds of yards long. There is a limit to how long a cable can be before a router or a switch must be put in between cables; however, this is a lot longer than most people setting up a home network will need to be concerned with.

With a wireless network, you can’t see the path between components, but they are no less real. Instead of cables, radio waves carry data. Though they may be affected by interference, just as a radio or TV signal, this is almost never an issue in a home network, almost never. Be aware though that metal inside your walls, microwaves, solar flares and the like can interfere with a wireless signal. Even walls can reduce the strength of a wireless signal.

When setting up our home network, you’ll need some equipment to send and receive the signals that will be carried, whether by radio or cables. A network interface card (or NIC), typically an Ethernet card is one component that you will need. These are common and very inexpensive and come in different range of speeds, anywhere between 10MB and 1 GB. The speeds depend on the card you use – a 802.11g wireless network works at 54MB per second, while a 802.11b network runs at 11MB per second. As prices keep dropping, the lower speeds are becoming less commonly seen.

A network interface card can be either cabled or wireless. The cards in two different devices on a network are hardly ever connected directly by cables, but rather are connected to a switch or a router.A switch is a simple device; it’s like a box with ports for the Ethernet cables to connect to. They are extremely inexpensive and work well for networks which don’t need an internet connection. Routers are more commonly used these days though; sometimes multiple routers will be used by home network builders.

A router does exactly as the name implies; it directs network traffic. It performs this function by means of IP addresses and software created for sending and receiving data between devices. Routers can be either wireless or cabled. Each can be found in many different models from different manufacturers. There are different built in software’s with different functionality; some feature antivirus software built in. These routers differ in their number of ports (which decides how many devices can be plugged in to the router). There is also a difference in the speeds at which they operate; they may not run at the speed they are rated at. For instance, a router rated at 54MB may actually run at 6MB.

There are other components which will be part of your home network, such as a cable, DSL or satellite modem for internet connection. The devices listed above are what you’ll need to get started though with the basic set up of your home networks system..

Troubleshooting Four Common Network Card Problems

December 30th, 2009



As the network card is popularized all over the world, it has become a bridge between computers and the network. Once the network adapter goes on the fritz, PC users will suffer lots of unaccountable troubles and feel helpless. Here I will list some common network card malfunctions and their solutions:

Network connection

A network card usually has two indicator lights (LED): the green light shows that the card is receiving electricity; the orange (10Mb/s) or red (100 Mb/s) light indicates network activity (sending or receiving data). When a network card is working regularly, its lights are sustained (flickering when transmitting data), but if the lights become too bright or too dark every now and then, furthermore, computer drops online frequently, most possibly this net card and its PCI slot are poorly connected. Different from other PCI devices, if you often plug net card or move computer, the network connection is easily loose because of poor contact. You can fix this glitch by plugging the net card again or changing to another free PCI slot. Moreover, if there is too much dust on the card, the card’s golden finger is severely oxidized, or the network cable connector is broken, the network connection also would be unstable, well then you need to clean the card, wipe the golden finger with some paper or change a connector.

Drivers

Network card is the same as other hardware devices: its imperfect driver may bring about problems. If your card encounters some inexplicable errors, you can download and set up the latest drivers from some professional websites to repair these errors. In case your network adapter’s malfunction happens after you updated driver, you can restore the driver with the driver program that came with your adapter.

Magnetic field problem

Network adapter is easily interrupted by the magnetic field, so you should avoid putting your computer near to the devices like microwave oven, fridge or TV that have a large and strong magnetic field.

Network cables

Poor network cables and connectors would also affect your net card working. In addition to selecting better twisted pair, you should also note that whether the connection between your network adapter port and connector is in good, and whether the order of the data lines in the connector accords with the international 568a and 568b network cables (especially those self-made connectors).

How to Build a Simple Home Network System

October 19th, 2009



Many people have relatively uncomplicated needs for their home networks. Even now that multiple computers within a single home are common, the systems are often not networked, with file transfer being done by means of “sneaker net”, or copying files to and from a CD or by Sending files via email.

This is a great time to build your own home network, if you have always wanted to. The costs and the complexity of the systems are lower than ever. Just getting past the technical terminology used is the biggest barrier for many new home network builders. The equipment you’ll need is pretty simple. You’re going to need Cat-5 (or Ethernet) cables for a wired network. Think about where you plan to set up your computers to determine how much cable you’re going to need and then add on about 1/5 more cable than that – you always need a little more than you think. If you plan to build a wireless network, you can skip the cables.

You’ll also need a switch or a router for all of these cables (or radio waves if it’s a wireless network) to connect to. A hub or a switch is just a box with ports to plug cables into – a switch has slightly more functionality than does a hub. A router is better and can handle internet connection sharing; it is almost a must for a home network. I say almost because you can use one of the computers on your network to handle internet connection sharing. However, it is in most cases far easier to just use a router instead of tying up a lot of the resources of one of your computers dealing with connection sharing.

You’re also going to need Network Interface Cards (or NICs) in each computer, printer or any other device you want to be on the network. These can be your standard 10/100 ethernet cards or 802.11b/g cards which can be used for a wireless network. If you are building a wired network, you can use Ethernet equipment with 10MB or 100MB speeds. They are both so inexpensive, that there is really no reason not to go for the 100MB equipment. These devices generally support equipment which runs in the older standard as well. There is also Gigabit Ethernet, but this is prohibitively expensive for many building a home network.

Install, attach and/or setup all hardware as per the manufacturers’ directions. Every device on the network needs to have at least one IP address of its own. IP addresses are those numbers you may have seen on the internet before, such as: 70-1-2-125. On a home network, your IP addresses will look like 192.168.0.1 or 10.121.0.1.

Your IP numbering should begin with the router. This device is the center of your network; imagine a star with rays of light emanating from it. Each cable or wireless signal is one of these rays of light. The ends of these rays are where your devices are. If the router has the number 192.168.0.1, then computers and other device should be numbered 192.168.0.2, 192.168.0.3. Don’t assign the same address to two devices.

You’ll have to read the manual for your router for the specifics on how to assign these addresses, as well as the documentation for your computer’s operating system.
