A technician is resolving an issue where a computer is unable to connect to the Internet using a wireless access point. The computer is able to transfer files locally to other machines, but cannot successfully reach the Internet. When the technician examines the IP address and default gateway they are both on the 192.168.1.0/24. Which of the following has occurred?

Question

Accepted Answer

B. The gateway is not routing to a public IP address. Since local file transfers succeed, the LAN configuration is correct and the computer's IP is valid. The inability to reach the internet indicates the default gateway is not forwarding packets to a public IP - this points to a WAN-side misconfiguration on the gateway, such as a failed ISP connection, missing default route, or NAT not functioning properly.

Answer

A. The computer is not using a private IP address. 192.168.1.x is a private IP address defined in RFC 1918, so the computer is in fact using a valid private address.

Answer

C. The gateway and the computer are not on the same network. Both the computer and gateway are on 192.168.1.0/24, meaning they are on the same network - this is confirmed by successful local file transfers.

Answer

D. The computer is using an invalid IP address. A 192.168.1.x address with a /24 subnet is a valid private IP address configuration, not an invalid one.
