The sign of any short range radio transmission could be picked up by any apparatus in range that is tuned to the exact same frequency. What this means is that anyone using a wireless PC or laptop in range of your wireless network might be capable of connect to it unless you take precautions.
Should this happen 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 knowing or permission. This could have an effect on your own use. You could discover your connection slows down as it shares the access to the Internet with an increase of users. Many house Internet services have limitations to the quantity of information you can download per month - a "Freeloader" could surpass this limit and also you find your Internet bill charged for the additional amounts of data. More seriously, a "Freeloader" may use your Internet connection for some hassle or illegal action. The Police may follow the Internet connection used for such activity it might lead them straight back to you personally.
Eavesdropping - As information is transmitted an "eavesdropper" may link to your wireless network and see all the info as it passes by. This is completely undetectable by the user as the "Eavesdropper" is merely listening not transmitting. Such sensitive information as bank account details, credit card numbers, usernames and passwords could be recorded.
Hacking - Even when the security characteristics of a wireless network happen to be switched on unless these attributes are set-up right then anyone in range can hack in to the network. All home wireless network routers have a standard username and password for the management of the network. All a hacker needs to do is go through the record of standard usernames and passwords until he gets access. A hacker may subsequently apply your network for the above mentioned or gain access to your own PC - your firewall may not keep him because, as he's connected to your network, he is within the trusted zone.

Most wireless network gear, when it comes from the box, isn't protected against these threats by default. This implies you have to configure the network yourself to make it a protected 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's controlled or obtained. This means the advice that follows may appear somewhat technical because we can only just tell you what you must don't how to do it. You need to browse the manual or help files that came with your equipment so that you can determine the best way to make a secure wireless network.
1. These last two (ad hoc and peer to peer) mean that network devices such as PCs and laptops can connect directly with each other without going via an access point.
2.Select an obscure name for the network - This significant tip to having a protected wireless network is probably not used by about 99% of home users. The default SSID is normally the name and model of the wireless router or Internet provider e.g. NetgearDG834G or Sky9091. Should you depart the SSID like this it makes hacking really easy so alter the SSID as soon as you set up your network. Do not use your address, house name or family name these are too simple to imagine.4. Switch off the SSID broadcast. This suggestion goes in conjunction with No3 in creating a secure wireless network. This means that anyone wishing to connect to your wireless network must understand its SSID i.e. the name of the network.
3. Change the name and password of the management user for the wireless router however don't forget to make a note of what you change it to. A secure wireless network could have an admin user ID that's difficult to guess and a strong password which uses letter and numbers.
5. It is also a good idea to create the time the network can be used if the unit enables it.
6.Use MAC filtering If your wireless router or access point enables it, MAC filtering readily adds yet another layer to turn your wireless network protected. Every network card (the device installed in PCs and notebooks that connect it to your network) has its unique code, called a "MAC address". In Windows XP you can see the MAC address by right-clicking on the network connection, pick "status" and then the "support" tab. The code tagged "physical address" is the MAC code for this network connection apparatus. Make certain it is the wireless network connection you pick as the LAN connection will have a different MAC address. Most wireless routers or access points permit you to list the MAC codes which you wish to use the network. What this means is that you must grant permission to any PC or laptop that really wants to connect to the network.
7. Use encryption. This is the bedrock of any secure wireless network and means the data that passes within the radio can only be decoded with the proper system of encryption along with the correct password. Presently there are three methods of encryption for wireless networks generally referred to by their acronyms: WPA2, WPA-PSK and WEP. Each procedure can only be used if all of the equipment on the network gets the ability. As WPA2 is the newest way of encryption, unless you have recently got the latest PCs, laptops & network device you likely will never manage to utilize it. WPA-PSK is another best and can be obtained on most hardware. If you're using older access points and network cards, you may find that you can just use WEP. Be sure to utilize a word or phrase that might not be easily estimated.
If you're able to set all seven of the tips in operation you'll have a very protected wireless network.
