If I am reading your question correctly, I would imagine it is because the computer is not on the same network...
**The computer has an invalid default gateway address**
Incorrect default gateway.
This is usually used to describe the Internet. A few computers connected together is a computer network. A few computer networks connected together is a network of networks.
Computer network : A collection of computing devices that are connected in various ways in order to communicate and share resource. Usually, the connections between computers in a network are made using physical wires or cables.
Modem.
Computer network.
Two different networks are connected by a router. Switches are used to connect network devices within networks.
Computer Network is all about sharing Information & Resources amongst Users & Devices within network. Computer Networks enables efficient usage of Resources (Such as printers, scanners etc) so that multiple devices for same functionality aren't required at every user's place. Computer Networks can provide Central Stored information & makes them available to all permitted Network users or devices.
Two types of computer networks are LAN (Local Area Network), which connects devices within a small geographic area like an office or building, and WAN (Wide Area Network), which connects devices over a larger geographic area, such as across cities or countries.

Data highway is a network of computer networks, other devices, and switching systems used for the transfer of digitized information.

Network management systems is referred to the combinations of hardwares and softwares used to monitor and administer a computer network or networks. It manages the network elements, also called managed devices.

Networks provide resource & information sharing among the devices. Internet is Network of Networks that provides access to resources& information to users spread across the earth & having an Internet connection.

Modem.
Computers that are connected to each other create a network. These networks are often configured with "public" internet Protocol (IP) addresses -- that is, the devices on the network are "visible" to devices outside the network (from the Internet or another network). Networks can also be configured as "private" -- meaning that devices outside the network cannot "see" or communicate directly to them.
