Wireless networks, frequently abbreviated to "Wi Fi", allow PCs, notebooks and other devices to "speak" to each other using a short-range radio signal. However, to produce a secure wireless network you will need to make some developments to the way in which it works once it is switched on.

The sign of any short range radio transmission could be picked up by any device in range that is tuned to the same frequency. What this means is that anyone with a wireless PC or laptop in range of your wireless network could be capable of connect to it unless you take precautions.
If it happens then your network and PC are vulnerable to any or all of the following:
Freeloaders - Most wireless networks are accustomed to share a broadband Internet connection. A "Freeloader" may connect to your network and use your broadband connection without your knowledge or permission. This may have an impact on your own use. You could notice your connection slows down as it shares the access to the Internet with increased users. Many dwelling Internet services have limitations to the total amount of information you can download per month - a "Freeloader" could exceed this limitation and you find your Internet bill billed for the excess amounts of information. The Police may trace the Internet connection used for such activity it would lead them straight back.
Eavesdropping - As information is transmitted an "eavesdropper" may connect to your own wireless network and view all the info as it passes by. This really is totally undetectable by the consumer as the "Eavesdropper" is only listening not transmitting.
Hacking - Even when the security features of a wireless network have been switched on unless these attributes are set-up correctly then anyone in range can hack into the network. All home wireless network routers have a standard username and password for the management of the network. All a hacker must do is go through the listing of standard usernames and passwords until he gets access. A hacker may then use your network for some of the above or gain access to your own PC - your firewall might not prevent him because, as he is connected to your own network, he's within the trusted zone.
Most wireless network gear, when it comes out of the carton, is not protected against these dangers by default. This means you need to configure the network yourself to allow it to be a protected wireless network.
The best way to fix a wireless network

Although all wireless gear marked as 802.11 will have standard features such as encryption and access control each maker has a different way it is controlled or accessed. This implies that the advice that follows may appear somewhat technical because we can only just tell you what you must do not how to take action. You must browse the manual or help files that came along with your equipment so that you can find out just how to make a safe wireless network.
1. Use encryption. This really is the bedrock of any protected wireless network and means the information that passes over the wireless can only be decoded together with the proper system of encryption and the proper password. Each method can only be used if all of the gear on the network gets the capability. As WPA2 is the most recent way of encryption, unless you have recently got the latest PCs, notebooks & network device you likely will never be able to use it. WPA PSK is the next greatest and can be obtained on most hardware. In case you are using older access points and network cards, you could find that you could just use WEP. Each system requires a "key" (a word or phrase used to create the encryption work). Be sure to use a word or phrase that might not be readily guessed.
2. Create your network infrastructure as "access point" and not "ad-hoc" or "peer to peer". These last two (ad hoc and peer to peer) mean that network devices for example PCs and notebooks can connect right with each other without going via an access point. You might have more control over how devices connect if you place the infrastructure to "access point" and so will result in a much more secure wireless network.
3. choose an obscure name for the network - This important trick to having a secure wireless network might be not used by about 99% of home users. Should you depart the SSID such as this it makes hacking very easy so alter the SSID when you set up your network. Don't use your address, household name or family name these are too simple to think.4. This hint goes in conjunction with No3 in developing a protected wireless network. This means that anyone wanting to connect to your own wireless network must know its SSID i.e. the name of the network.

6. Unplug the wireless router if you are going to be away from home (or the office). It's also a good idea to create the time the network can be utilized in the event the device enables it.
7. Use MAC filtering If your wireless router or access point enables it, MAC filtering readily adds an additional layer to make your wireless network protected. Every network card (the apparatus installed in PCs and notebooks that connect it to your network) has its own unique code, called a "MAC address". In Windows XP you can start to see the MAC address by right-clicking on the network connection, pick "status" and then the "support" tab. In the support window click on "details". The code labeled "physical address" is the MAC code for that network connection apparatus. Make sure it's the wireless network connection you pick as the LAN connection is going to have distinct MAC address. Most wireless routers or access points let you list the MAC codes that you need to use the network. This implies that you must grant permission to any PC or laptop that wants to connect to the network.
When you can place all seven of these hints in operation you should have a very protected wireless network.
