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

Answer 1

A router and an access point (AP) serve different but complementary roles in a network. Here are some key functionalities that a router offers that an access point does not:

1. Network Address Translation (NAT): Routers can manage traffic between the internet and the local network by translating private IP addresses to a single public IP address (and vice versa).

2. Routing: Routers direct data packets between networks, deciding the best path for data to travel over the internet or between different subnets. Access points, in contrast, do not make these routing decisions as they operate primarily within a single local network.

3. DHCP Server: Routers often function as Dynamic Host Configuration Protocol (DHCP) servers, automatically assigning IP addresses to devices on the local network. Access points do not usually provide DHCP services.

4. Firewall Capabilities: Routers typically include built-in firewall functionalities that help secure the network by filtering incoming and outgoing traffic. Access points generally do not have this capability.

5. Quality of Service (QoS): Many routers provide QoS settings that prioritize certain types of traffic (like video streaming or gaming) to ensure better performance. Access points typically lack sophisticated traffic management features.

6. WAN Connectivity: Routers have WAN (Wide Area Network) ports that allow them to connect directly to the internet through a modem. Access points only connect to the network they serve and do not provide WAN connectivity.

7. VPN Support: Many routers can facilitate Virtual Private Network (VPN) connections and allow remote users to securely access the network. Access points do not provide VPN capabilities on their own.

8. Configuration and Network Management: Routers usually offer a web interface for managing the entire network configuration, including security settings, firmware updates, and monitoring connected devices. Access points are more focused on the wireless aspect of connectivity.

In summary, while an access point extends the wireless coverage of a network, a router is essential for managing network traffic, addressing, and connectivity to external networks, making it a central hub for both local and wide area networking.
