Protecting your Wi-Fi network is a must to prevent one (or more) people from connecting to your network, block the path of hackers, protect yourself from malicious activities, and protect your data and online activity. It is indeed possible that unscrupulous users will use your Internet network without your consent. Even hackers can take advantage of your network’s fragility to increase the number of scam attempts. Hence the importance of securing your Wi-Fi network.

You may not know this, but all Internet boxes available on the market today allow you to secure your Wi-Fi network with different levels of security.

In this guide, we’ll look at the best practices you should use to keep your Wi-Fi network secure.

Why secure your Wi-Fi network?

In the age of mass PC, Mac and portable devices, Wi-Fi security threats are on the rise. Injecting codes, stealing personal data, or even simply reading data shared by hackers, the dangers of Wi-Fi are numerous.

Here are a few reasons why you need to increase the security of your Wi-Fi network:

A Wi-Fi network is less secure than a wired network.

The mode of operation of Wi-Fi networks makes them less secure than wired networks (Ethernet). Multiple devices (PCs, Macs, smartphones, etc.) can be connected to a Wi-Fi network and communicate with each other using radio waves. This increases the risk of data being intercepted on these waves. Obviously, the risk increases when said Wi-Fi network is not secure at all.

There are many ways for hackers to access the data of Internet users, especially if the Wi-Fi network is not secure. Through these few methods, they can access usernames and passwords, email addresses, conversations, and even browsing history.

A vulnerable Wi-Fi connection can be used by attackers to perform illegal activities (viewing inappropriate content on the Internet, inciting hatred, buying or selling illegal materials, stolen data or documents, etc.).

You can also use an unsecured Wi-Fi network to distribute malware (Trojans, ransomware, etc.) or simply connect your device (PC, Mac, smartphone, etc.) to your Internet box administrator for free. Connecting multiple devices to a Wi-Fi network can lead to network congestion and, as a result, slow internet speeds.

To ensure that your Wi-Fi network is safe and secure, and to be able to use your Internet Box with more peace of mind and ease, here are five best practices to adopt.

Change your default login information

Changing the default login credentials is the first thing to do if you want to secure access to your Internet box. Often the default password is “000” or “password”. For routers, the serial number printed on the side of the router is set as the network password. This means that anyone can access the network. Hackers can even take advantage of this to reconfigure the device and steal information.

To change the router connection information, simply access the device’s administrator interface at or Log in with the default ID and password, follow the instructions on the router interface to enter a new ID and password.

Change your SSID

Changing the SSID is another way to secure your Wi-Fi connection. This is the network ID (the name people use to find the network). It tells users the network type, making it easier for hackers to intercept data on a Wi-Fi network.

To change your router’s SSID, simply connect to it, select your Wi-Fi network, and enter a new ID. Don’t forget to disable “Broadcast Network Name”.

Encryption to secure Wi-Fi traffic

To ensure that your wireless network connection is completely secure, it is highly recommended that you check your WPA or WPA2 configuration. This feature, when properly configured, helps secure the process of authentication and access to the wireless infrastructure. This helps keep users from being eavesdropped on the network.

To do this, you must first log into your router and set the security mode or encryption level to WPA2.” The most recommended setting is WPA2-PSK. Some routers that are compatible with WPA2 (but not WPA2-AES) use the WPA2-AES/TKIP encryption protocol.

The WPA2-AES/TKIP encryption protocol enhances WEP security by integrating the Extensible Authentication Protocol (EAP). The latter guarantees secure access to the network and implements an encryption method to protect data during transmission.

Set up a host network

Setting up a second Wi-Fi network is another way to protect against intrusion attempts. When your friends come to your house, the first thing you need to ask is the Wi-Fi password. To keep your Wi-Fi network secure, some routers offer the ability to specify two networks. This second network can be reserved exclusively for guests. If your smartphone is lost or stolen, you will be sure that your SSID and Wi-Fi password will not be in the reach of hackers.

Set up firewall

The firewall acts as a barrier against any attempt to execute commands on the wireless network. Only authorized traffic enters and exits. To take full advantage of this, make sure that no one from the outside world can connect inside. It is listed as “Any: DISABLE”.

Another good setting is to enable Ping blocking if it is compatible with your router. In this case, the router will respond if someone sends “Ping” to it. This prevents hackers from knowing if you are there or not.

You should also consider blocking “fragmented packages”. To infiltrate a Wi-Fi network, hackers use fragmented packets that are deliberately poorly crafted to confuse a router or computers that can no longer tell good from bad information.
