There was a time when computers weren’t something ordinary people could afford. Back then, only the rich could buy them and the only networks in the world were those run by governments or large companies. Today, the picture is most certainly different. An average family’s home can have a network of computers owned by each family member and their Internet connections are fast and topnotch. Some families even use wireless computers and though cost is no longer an issue, information security definitely is.
What makes wireless networks sensitive sometimes is the fact that signals can go everywhere and are very hard to detect. This makes hackers very happy then, because now, they can hack any wirelessly connected computer and very easily at that. There’s no need to install Trojans or keyloggers. They just have to connect to that wireless network with their own laptop and start stealing information from those that are already connected. This is why wireless security should never be taken for granted. Imagine having a close neighbor connecting to your network without your permission. The risks are always there but it doesn’t mean wireless networking is bad altogether.
In fact, only unsecured wireless networks can be a headache which means as long as you secure yours, you shouldn’t have any problem. If you’re not exactly technically savvy, you might think it’s some complicated task that needs an expert to do. On the contrary, you can do it on your own and quite simply.
First off, because networks run on ID’s, you need to secure your own network’s ID so unauthorized access is prevented. Laptops will come with a default SSID (Service Set Identifier) or ESSID (Extended Service Set Identifier). If you don’t customize it, you can expect hackers to come prying in because it’s actually very easy for them to research on the default identifiers for each wireless computer manufacturer. This is why it’s extremely important that you change you SSID or ESSID into something unique to you.
Then you need to disable Identifier Broadcasting so you don’t get to announce to the whole world that you’ve got this wireless network that just about anyone out there could hack into. A manual that comes with your device will have instructions for this.
The third step in securing your wireless network is to enable Encryption so only authorized people able to access your information. There are actually two types of encryption you can use – WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). For maximum security, it’s better to go for WPA which provides stronger protection than WEP which has many flaws and is quite easy to crack.
Firewalls are, of course, basic to every Internet security campaign, whether wired or wireless, so check your manual and set up your firewall to block unwanted traffic. Anti-virus software as well as anti-spyware and anti-adware should also be installed and updated regularly to ensure maximum protection.
As a final step, change your default password into some unique to you. Refrain from using birth dates and anniversaries which are pretty easy to crack. The most secure password could be a random combination of letters, characters and numbers.
As a general online security measure, an IP hiding software just might be very helpful. Because it allows you to surf with fake a IP address, you don’t leave a trail for hackers to follow back to you. This way, you keep these unwanted elements at bay and you simply enjoy the added freedom to your Internet activities.

A Step-By-Step Guide to Setting Up a Wireless Network
March 1st, 2010
Wireless networks are getting more popular as more days go by. They are easy to install and practical to use when it comes to surfing the World Wide Web from anywhere inside the house. This is why wireless networks are attractive in the eyes of internet users. It is fairly easy to set up a wireless network; however, you have to know several simple things before trying to begin your setup. To get better understandings of wireless networks, you can read on protocols of wireless networking.
To set up your wireless network, you would require a broadband online connection with either a DSL modem or cable. Usually, the regular home setup involves a desktop computer that is directly plugged into a modem. If you are reading this, we can presume that you already own a laptop which you wish to wirelessly connect to a personal computer which has an internet connection. You will require some hardware to do this, such as a wireless router, a wireless USB network adapter for your desktop computer and a card-based personal computer network adapter for the laptop. Obviously, it would be recommended to opt for the same vendor as any extra hardware that you purchase. Refer to documentations that come with the hardware for any process of installation.
After installing all of the required hardware, you can start with the setup. First of all, you have to turn off or unplug your DSL modem before connecting your wireless router onto the modem. If you need help, simply check your hardware’s documentation. After this has been set up, your computer is going to connect to the router wirelessly. Next, you have to configure the wireless router. You can use Internet Explorer to go to the configuration page of your router.
The majority of default settings are safer to be left alone; however, there are several things that will need configuring. You have to choose a one-of-a-kind SSID or name for your wireless network, which will also be your network’s name. Ensure that nobody near you is making use of the exact same name. Next, if the router needs it, provide a one-of-a-kind passcode which it will put to use in order to generate several keys. The last thing to do before finishing your router configuration would be to set an administrative password. Pick a password which is long and hard to guess for security purposes. Ensure that you save each configured setting. Actual steps that are involved with setting configuration may vary, depending on your type of router.
Next, configure the network adapter of your laptop. It is quite easy to follow the on-screen instructions on Window’s XP when it comes to this. Right-click on the wireless network icon within your taskbar and go to “View Available Wireless Networks” after the menu appears. The window of Wireless Network Connections will show up. Here, you should see your chosen name listed for the wireless network. Click on “Refresh network list”, if the network does not appear. After that, you will be asked to enter a key as you have written down within the key boxes of Confirm network key. Choose Connect. Then, you will see the progress of your connection while it connects to the network. Once you are connected, feel free to close this window. Your wireless connection is now set up.
