How to Secure Your Wifi Connection ?

Did you know people could access to your computer if they are connected to your wifi ? They could steal your personal information, crash your wifi network and more ? How can you stop this ? Well simply secure your wifi connection ! To do so, you'll only need to read the following in order to understand correctly how it is done correctly.

Securing your wireless network is a necessary step to prevent a malicious user to use your wireless network son. Here are the steps you'll need to follow in order

Change the user password of your wireless router:

The access to the configuration utility of your router is secured with a username and a password. This page is accessed by typing the IP address of your router in your internet browser (for instance 192.168.0.1). The first step in securing your new Wi-Fi network is to change the password by going to the option to change it. By default the username is admin and so is the password.

Set the network name (SSID):

Any WiFi network has a given name: we call it the SSID (Service Set IDentifier). The second step to follow in order to secure your wifi is to change that name and hide it from the malicious users that will, for sure, do whatever they can in order to steal personal information or damage your network. To prevent this go to the configuration utility of your router and change the default SSID name but try not making it too simple. Then disable the SSID broadcast of your wireless network by checking the indicated field. If you do so, it will not appear in the list of possible wifi connection of nearby users.

Enable encryption on your network (add a security key):

Before using your wireless network, it is useful to encrypt it with a numerical key, making it only available to users who know the security key. Two types of encryption data are currently available: WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). If your router and your wireless adapters support both of these encryption systems you should opt for a WPA encryption key. However, if your hardware, unfortunately, does not support WPA, then enable WEP. The manipulation is very simple because the encryption is created from a sentence, a word or a combination that you will type in. You must enter a 5-letter word minimum or a phrase in the text box and the router will generate different codes depending on the encryption type. In order to never forget them, you should write them down (one per network is enough) because they will be used to connect each computer or other internet-compatible devices on the network.

Filter MAC addresses:

Devices (Computers or Phones) connected to a wireless network have a network card fitted with a specific address: a MAC address (moreoever, note that a computer is also defined by its IP address). In the configuration utility of your router, you must activate the filter option and enter the MAC addresses of each of your devices. Thus only these devices (known on the network by their MAC addresses) can gain access to the network.

Now that you've configured your Wifi correctly anf securely, you may now connect your devices to the Wifi. Remember that since you made all these changes you can't just double click on the wifi network and name and get internet access. To do connect your computer or phone to the wifi follow the next paragraph.

Configure the Wifi devices:

For each device that can connect to the network you will need to indicate the information listed above. After researching your wireless network, you must change the SSID to match the one you specified for the router. Then specify the key digital encryption that was specified in the utility ocnfiguration the router. Once done, your device should connect to the router and the internet.
