<human>:  What are the different types of WiFi networks and their features?
<bot>: The different types of WiFi networks are: 
1. Infrastructure WiFi Networks – These networks use Access Points (APs) to provide wireless access. Features include secure authentication options (like WPA2), bandwidth control, and quality of service (QoS) settings.
2. Ad-hoc WiFi Networks – These networks work without the use of an Access Point. Features include simple setup, no configuration, and faster cross-platform performance.
3. Mesh WiFi Networks – These networks are composed of multiple Access Points, allowing for better coverage and the transfer of data between multiple APs. Features include secure configuration, centralized management, and signal strength and quality optimization.
4. Wireless Distribution System (WDS) Networks – These networks are a combination of two or more Access Points, connected wirelessly. Features include extended range, bandwidth support, and signal-to-noise ratio improvement.
5. Virtual WiFi Networks – These networks simulate a physical WiFi network and allow users to share data among their devices. Features include the ability to share connections with multiple devices and virtual private networking (VPN) support.
