A guest network allows visitors to connect to the internet without compromising the security of your main network. Ensure that the guest network has its own password, separate from the primary network.

Additionally, consider implementing network segregation through the use of virtual LANs (VLANs). VLANs create separate subnetworks within your network, enhancing security by isolating different groups of devices from one another.

2.2 Enable Firewall Protection

An important security measure for your wireless network is to enable a firewall. A firewall acts as a barrier between your network and potential threats from the internet, filtering incoming and outgoing network traffic.

Your Wi-Fi router may have a built-in firewall, which should be enabled and properly configured. Additionally, consider installing a software firewall on each device connected to your network for an added layer of protection.

2.3 Disable WPS (Wi-Fi Protected Setup)

Wi-Fi Protected Setup (WPS) is a feature designed to simplify the process of connecting devices to a Wi-Fi network. However, it can be vulnerable to brute force attacks, allowing unauthorized access to your network.

It is recommended to disable WPS on your router to eliminate this potential security vulnerability. Consult your router's documentation for instructions on how to disable WPS.

3. Educate Users on Good Security Practices
