One problem with wireless networks is that people who have wireless devices that are within the range of your network can access them. Even if you have set up a password for your wireless network, that password can also be hacked and access to your network can be gained. One way to further tighten up your network security is through MAC filtering.
MAC filtering is a network security procedure that only allows access to registered MAC addresses. A MAC address is the unique ID of a network device; no two computers or network device has the same. What this means is that only registered and authorized machines can access your wireless network. So even if they somehow managed to break or hack your password, they won’t still have access if their address is not registered. This is a very effective way to ensure the network security of your wireless home network.
What you need to do is enable the MAC filtering function of your wireless router or access points. Most routers at present have this function. Next, you need to input the MAC address of the computers in your home network. Getting the MAC address is different from one operating system to another, but this should be found in the properties of the network device. Check your computer’s manual or technical support for the procedure on getting the MAC address.
So, if you’re very particular about the network security of your wireless network, then one thing you can do is to enable MAC filtering in your network.

Do You Have Two Or More Computers in Your House? Create a Network in Your Home and Share Resources
November 18th, 2009
So the journey begins and our first stop is to establish the basics of a network. This Basic Networking guide will help you understand the following:
• The Hardware used to create a network
• The correct operating system to use on our network
• Understanding how networks work
So buckle up your seatbelt, here we go! Are home networks Complicated to set up? The short answer to the heading above is No. The long answer… Heck no!
Believe it or not, setting up a network in your home is not complicated by any means. All you need is a point in the right direction and a little guidance. Together with this Basic Networking guide we will create the best network for you and your family.
So, what’s a network?
Simply put, a network is when two or more computers are connected and sharing data. That’s it! Nothing more, nothing less. These computers can be connected in a variety of ways and we will touch on that a little later. What we want to do now is work out the type of network we need in our house.
Why do I need a network again?
There are a lot of benefits to having a network. If you have more than one computer in your house you really have no reason not to have them networked, and by networking them you will be able to:
• Share printers, CD-ROM drives and other removable drives between the computers.
• Eliminate having to transfer files from one computer to another using a floppy (do they still exist?) or CD-ROM and share files directly between PCs. ( a great advantage if you are lazy like me)
• A huge benefits is you can share your internet connection with the other computers in your home
• Store only a single copy of large files, saving space on the other PCs’ hard drives.
Fantastic, how do I get started? Whoa there! Before we can start anything we need to plan first. “Plan?” I hear you say. Yes, plan! Building a network is a kin to building a house; we need a strong foundation to build upon. I can hear the groans already! You will be thanking me later.
There are two types of schemes you can use in a Network; Client/server network and peer to peer.
In the client/server network, you have one computer that acts as the server (the manager of the network or files), which controls the way other computers (known as clients) access the network, whether that being file sharing or running a program. Servers play a very important role on this particular type of network
Most home networks are based on the peer to peer Network, which has more relaxed controls thus is a better network for you and your family.
Operating Systems
This basic Networking guide assumes your operating system (OS) is at the very least windows 98 Second Edition. Although Windows XP would be preferable it’s not a requirement. The reason for this is because networking was built to function from the ground up in windows 98 SE to windows XP. The following OS will work perfectly with networking:
• Windows XP
• Windows 2000
• Windows NT
• Windows ME
• Windows 98 SE (Second Edition)
Also all these OS versions have a pretty little nifty tool on them known as Internet Connection Sharing. This allows all computers to share the internet, so while you are reading an e-mail on your laptop, your kid can be checking out their facebook page on the PC.
Each computer must have a Network interface card otherwise known in short form as a NIC. Traditionally a NIC is a little electronic card that goes inside your computer right on its mother board, I use the term traditionally as not all NICs are cards anymore, and we now have network adapters that are connected via USB (Universal Serial Bus).
How to Connect – Cables, wires or thin air?
Now we must decide the type of connections we will use to connect our computers. This is very important as the type of connection we use will affect the speed that data travels across the network. Why is speed important? Well waiting a long time for a file to open in a software application or for a file to be copied from one machine to another can be very frustrating to put it mildly. We have four different ways to connect our PC’s, each have their own advantages. Let’s look at them shall we?
Ethernet Cables
• The connection type of choice for many businesses. Fast and reliable
• Can carry data up to1000 mbps across a network depending on the rated speed of the NIC cards
• Used by most businesses to connect their computers
• Though similar looking to telephone wire, it is designed to carry data unlike telephone wire which was designed to carry voice
• You will need a concentrator (we will get to this later,) to use Ethernet cable.
• The connector at the end of the cable looks like the connector at the end of your telephone cable, but it’s actually slightly fatter.
Telephone Line
• Connect each computer’s NIC (has to be a Telephone-cable NIC. Have you visited the NIC page yet?) to the telephone wall jack using a regular phone cable.
• Telephone cable is inexpensive and is available every where, including your super market
• Networking process uses part of the line voice communication doesn’t, so you can still make calls whilst on the network
• Can transmits data up to 10mbps
• Is increasing with popularity.
• You will need a splitter for telephone wall jacks, to use your phone in the same jack
• If you have multiple lines in your house, all computers must be connected on the same line (same number)
Wireless connections
• No wires to trip over
• A very popular choice
• Best used on Windows XP, so would be best option to have all PC running XP
• Requires network adaptor that can receive and send wirelessly.
• Frequency can travel roughly 150 feet, passing through ceilings, walls and floors.

How to Network Computers – Setting Up Windows For Our Network
October 24th, 2009
Configuring our computers for our home computer network
After all the hardware for our home computer network has been setup , we now have to setup our computers to allow communication with each other. Though we have our hardware in place it remains useless unless the computer knows what to do with it, and it is you who has to tell it what to do with the hardware. In this article we will go through the process of setting up the software side of our network, which is not very complicated, actually a lot of it is automated or semi-automated where the computer does most of the work.
Some of the stuff you need to do is routine technical stuff like installing the drivers (software that controls the hardware devices like the NIC) on your computer. Also you will need to set up each computer so they are ready to share their files on your home network.
Note for Wireless Users: If you are using a wireless router on your network then you will need to install the router first. Though installation procedures vary among manufacturers, for the most part they all have the same general setup
Drivers for hardware
Your network connectors, whether they be ISA, PCI or a USB connecter are all hardware devices which will need you to install little software programs known as drivers. Drivers help the operating system communicate with hardware, telling the hardware what to do and when to do it.
After you physically install the network adaptor on your computer, the next time you turn it on, windows should automatically discover it and request for a driver to be installed. This very cool feature in windows is known as plug and play, which goes to work while windows start up. The plug and play feature will want to install your hardware straight away and will request for you to provide the correct information for it to be installed properly.
With USB connectors you can plug the device into the computer while it is on and windows will automatically detect it for you and bring up the “add new hardware” wizard. This ability to install hardware whilst the computer is on is known as a hot installation (by techies), and its one of the coolest things about USB devices… Get it?… HOT installation… COOLEST thing about USB?
Come on that’s funny!
Oh Never mind!
There are times the plug and play feature in windows will not detect your new hardware, in that case it will be up to you install the driver manually.
Protocols to start Communication
Now windows has the appropriate drivers to communicate with our network adaptors, it is time for our computers to start communicating . In order for our computers to communicate, they need to have the same network protocol (That’s tech talk for the language computers use to communicate). There are two types of protocols used for computer to computer communication, TCP/IP or NetBEUI. Depending on your version of windows each one will be installed automatically. Windows XP installs TCP/IP automatically so if you wanted to use NetBEUI on XP you would have to install it using you windows CD, and vice versa if you were using windows 98.
Each computer must be installed with the same protocols in order to communicate; this installation binds the protocol and the network adaptor together. As soon as each computer can talk the same beautiful language, then services can begin on the network. Each task that you want to perform on a network, like file sharing, print sharing and logging on to the network is known as network services.
Naming computers and Work groups
There is one more task to do in order for our computers to communicate and share resources. The Microsoft Network system is very anal when it comes to networking rules and demands to know who’s who, who’s where and what’s what. Because of this computers must be given a name (each one having to be unique, so you can’t have two computers with the same name).
Also you must give each computer a work group (the group in which you network exists, so each computer must be in the same group) Windows Networking wizard If you are using Windows Me or XP you do not have to go through most of this, you can use windows home networking wizard to set it up for you.
The windows home networking wizard walks you through the process of setting up your network, it also sets up the shared internet connection for you. A lot of people do not like using this wizard because they say it complicates things (I can’t say I am too fond of it my self). I would recommend you doing it all manually it helps you understand how windows works a lot better.
