What is the main function of a router in a wireless network?

• A. To act as a firewall that blocks all traffic.
• B. To manage the connections and communications between devices and the internet.
• C. To store user credentials and policies.
• D. To route only wired traffic.

Answer: (B)

Routing packets between devices on your local network and out to the internet is the primary role of a wireless router. It acts as the traffic director, using routing tables to decide where each data packet should go. In a home or business setup, the router also handles functions that support this role, such as Network Address Translation so multiple devices can share one public IP, and DHCP to automatically assign IP addresses. Many routers also include the wireless access point capability, enabling devices to connect via Wi‑Fi and still be part of the same network.

This isn’t just about filtering traffic or storing credentials. A router’s main job is to determine the correct path for data and forward it toward its destination, whether that destination is another device on the LAN or an external network like the internet. That’s why routing only wired traffic isn’t accurate—the wireless connections are routed just as well.
