What added functionality does a router have that an access point does not

Answer 1

A router and an access point serve different purposes in a network, and while both can provide connectivity, a router has several functionalities that an access point typically does not have. Here are some key functionalities that a router provides that an access point does not:

1. Network Address Translation (NAT): Routers can assign private IP addresses to devices on a local network and manage their connections to the internet using a single public IP address. Access points do not perform NAT.

2. DHCP Server: Routers often include a Dynamic Host Configuration Protocol (DHCP) server, which assigns IP addresses to devices on the network automatically. Access points typically do not have DHCP capabilities and rely on the router to provide IP addresses.

3. Routing Capability: Routers manage traffic between different networks (e.g., between your local area network and the internet) and can direct data packets efficiently based on IP addresses. Access points only provide network connectivity to clients and do not manage routing between networks.

4. Firewall: Many routers include built-in firewall features to help protect the network from external threats. Access points usually do not have a built-in firewall.

5. Network Management: Routers often come with advanced network management and security features, such as VPN support, port forwarding, access control lists, and quality of service (QoS) settings. Access points generally do not provide these management features.

6. Multiple WAN Connections: Some routers support multiple WAN connections for load balancing or failover, allowing for more reliable internet access. Access points do not offer such capabilities.

7. Wi-Fi Security Management: While access points provide wireless connectivity, routers often have additional features for managing security protocols (like WPA3), guest networks, and advanced encryption methods.

8. Advanced Traffic Controls: Routers can implement settings like bandwidth prioritization, which is important for managing network performance, while access points typically do not have these capabilities.

In summary, a router serves as the central hub of a network, performing critical functions for communication between devices and the internet, while an access point primarily extends a wired network to wireless devices.
