A computer can access devices on the same network but cannot access devices on other networks. What is the probable cause of this problem?
- The cable is not connected properly to the NIC.
- The computer has an invalid IP address.
- The computer has an incorrect subnet mask.
- The computer has an invalid default gateway address.
The default gateway is the address of the device a host uses to access the Internet or another network. If the default gateway is missing or incorrect, that host will not be able to communicate outside the local network. Because the host can access other hosts on the local network, the network cable and the other parts of the IP configuration are working.
