How to Make Your Wireless Network (Wi-Fi) Hacker-Proof


Security has become second nature to people over the years, whether it's your home, car or belongings. Our computers are no exception, because digital thieves are ubiquitous and can be almost impossible to detect by the user. Preventing unauthorized access to your home or business wireless network (Wi-Fi) is an extremely important step to take because a hacker does not need to know you personally to target you and may be in a home. or an apartment nearby, or even parked in a car in the street. Wi-Fi hackers are known to bypass neighborhoods in search of wireless networks in people's homes, to access the various unlocked doors of a wireless router's configuration, and then to spend a day on the ground with your informations. In this article, we will step through the various configurations of your wireless router that leave your network vulnerable, as well as the steps to take to make your network virtually hacker-proof.

Step 1: The first thing to do is to connect to the configuration utility of our router. To do this, you must first determine the IP address of your gateway. You can do this by going to Start> Run and typing CMD. This will open a command prompt session. In the command prompt, type "ipconfig" without the quotes and press Enter. If this is done while you are connected to your network, several different numbers will be forwarded. The one we need is listed as "Default Gateway". Take the IP address indicated as "Default Gateway" and write down or copy it. If you are not familiar with IP addresses, it is a series of numbers separated by dots as follows: In fact, this particular IP address that I just To use as an example is the most common gateway, but yours can be listed as follows: something different. Now, with this IP address copied, open a web browser such as Internet Explorer or Firefox, then paste or type the IP address exactly as it appears in the address bar, and then press Enter. This will display the login page of your router. If you know your login information, enter them here. Otherwise, you will need to find the user ID and password of the manufacturer for your router. You can find it in the manual supplied with the router or by visiting the manufacturer's website under the model number of the router (you will find it on a sticker on the back, side or bottom of the router). ) You can first try common words such as "admin" for the user ID and "password" for the password, or "admin" for the user ID and password. If this does not work, refer to the manufacturer's manual for the user ID and password. If you set your own username and password and have forgotten them, or the manufacturer's default username and password do not work, if other people in your home have access to the router or if that last had a previous owner, the username and the default password may have been changed. In this case, you can restore the default values ​​by pressing and holding the reset button on the back of the router for at least 5 seconds. You can now login using the default user ID and password set by the manufacturer.

Step 2: Change your username and password if they match the manufacturer's defaults. If a user accesses your wireless network, he can easily connect to your router settings and change them as he sees fit.

Step 3: Change your SSID. Your SSID is the name you see for your wireless network when you search for open networks using a Wi-Fi enabled device. If the SSID is set to the manufacturer's default value, any anyone looking for an open network nearby can see yours and can, with a little research on the internet, determine the model number of your router, which will help them access your router's settings.

Step 4: Disable the broadcast of your SSID. Broadcasting an SSID simply searches for open network names on your device when you search for open networks in an area. If you disable your SSID broadcast, when people are searching for open networks, yours will not even show up. As a result, they will not even know that your wireless network exists. You will still be able to connect to your network by manually typing your SSID into your Wi-Fi enabled devices.

Step 5: Enable WPA2 encryption, if applicable. If WPA2 is not available, enable WPA encryption. If neither is available and only WEP is available, consult your router's manual or website for information on updating your router's firmware. An update of your router may include support for WPA or WPA2 encryption. If no update is available for your current router, you may want to consider buying a new router because yours is probably very outdated. WPA2 encryption is ideal because it is much more secure than WPA and especially WEP.

Step 6: Configure a pre-shared key, PSK key, or network key. Whatever the name of your router, it is the "password" of your network. This should not be confused with the password we changed in step 2 for your router. Your pre-shared key that you have set up should be impossible to guess and should include uppercase and lowercase letters, numbers, and special characters. It is very important to include all these elements so that it is almost impossible to crack, but do not do it so long that you need 5 minutes to introduce it into each device. If you have trouble remembering it, you can always check it at any time by reconnecting to your router settings.

Step 7: Enable MAC address filtering or MAC address authentication. This step is optional and should only be performed if no visitors are using your Wi-Fi network or if the devices that use your Wi-Fi network are still the same. A MAC address is essentially an identifier belonging to each activated Internet device or network and looks like this: 00: 20: e0: 00: 41: 00. Each device ever created has a unique MAC address to be able to be correctly identified on a network. as an individual. The use of MAC address filtering or authentication allows only specific devices that you have selected to connect to your wireless network. No external device will be able to connect because its MAC address will not appear in the list of authorized devices that you create. To add your Wi-Fi enabled devices to the access list, you must first obtain the MAC address of each device. For computers and laptops, you can simply go to Start> Run and type in CMD & # 39; without quotation marks. This will bring up a command prompt window. Then type 'ipconfig / all & # 39; without the quotation marks and press Enter. Something saying "Physical Address" should be listed somewhere up. Beside, you will see the MAC address of your computer. It can be listed with hyphens between 2 characters instead of two dots, as in the example above. This is correct, just make sure that when you enter the MAC address in the access list, you do it in the format required by your router. You may need to change all the hyphens in two points. Do this for all computers connecting your wireless network. For devices such as iPods, iPads, mobile phones, and so on, you will probably need to look up information about your device in the Setup menu (or perhaps elsewhere, depending on the device). Here, if it is a Wi-Fi compatible device, you will find the MAC address. Do this for all non-computer devices that connect to your wireless network and add them each to your access list. Do not forget that every time you buy a new device or visit someone and want to use your Wi-Fi network, you will need to perform this step.

It is important to perform all the steps to properly secure your wireless network, except for the optional step 7. Other security measures can be implemented, but the The above steps are the most important and necessary steps to prevent unauthorized access to your wireless network. If you followed all the steps listed in this tutorial, you can be sure that your wireless network is now virtually impenetrable.
