How to improve Wifi network security?

Recently, you feel that your home wifi network speed is much worse? There are many reasons that affect network speed and one of them is that someone may be using your home’s wifi network, affecting the page load speed when you are online. In this article, we will learn together a few ways to improve wifi network security.

Use strong passwords

A strong password is a password that contains at least 8 characters, including uppercase, lowercase, numbers, and special characters. Here is a good example of a strong password: “[email protected]@u#2s0nG”.

Also, avoid using your personal information, such as your name, date of birth, phone number, or easy-to-guess words like “password” or “12345678” when setting a wifi network password.

Another helpful piece of advice is to change your password regularly and don’t share your password with anyone.

Enable WPA2 security mode

WPA2 (Wi-Fi Protected Access 2) is the most popular wifi network security standard today. It is designed to replace WPA and establish a higher level of security for wifi networks.

WPA2 uses the AES (Advanced Encryption Standard) encryption algorithm for encrypting data transmitted between the device and the router. This helps prevent unauthorized access to your network and protect personal data

Enable automatic router firmware updates

One of the last ways to increase the security of your wifi network is to update your router’s firmware version. Most new versions include security fixes, performance improvements, and bug fixes. Therefore, updating the router is very important.

Firmware update steps can usually be done in the admin page or installed at 192.168.1.1 or 192.168.0.1. If you have any problems with the update, you can restore the configuration using the previous backup file.

Turn off automatic sharing

Disable the router’s automatic sharing feature to prevent others from accessing your network. For each different router brand, there will be different specific steps to turn off this feature. You can easily find a way to turn off sharing with the syntax “turn off automatic sharing” + your router’s brand name.

Use firewall

When the wifi network firewall is turned on, the firewall will help block connections from unknown or malicious devices that have the ability to access your network. It will also help block network attacks by inspecting packets traveling over the network and blocking invalid or malicious packets. The wifi network firewall can also restrict the access of devices, allowing only trusted devices to access the network for a certain period of time.
