A network connection is a method of transmitting data from one computer or related device to another. There are four main steps required to troubleshoot a network connection: check the physical connectors, confirm the software settings, eliminate resource issues, and verify the original specifications. Common uses of network connections are to connect a computer to printers, the Internet, and other computers.
A wireless router.
The first step in troubleshooting a network connection is to check all physical connectors. Look for loose connections, exposed wires, and plugs in the wrong outlets. The network jack looks like a telephone jack, and it’s easy to put it in the wrong jack. If you are using a wireless router to manage network connections, verify that the unit is working properly. Power surges can cause the router’s operating system to freeze, resulting in a network connection failure.
A network hub.
Check your network management software settings. The types of software vary, but they all record the Internet Protocol (IP address) of the connected computers, track data transfer rates, and indicate which hub or switch the computers on the network are connected to. Write down the main network operating system settings and check each individual computer to confirm they are correct.
View the list of current jobs or activities running on the network. A job that is using all resources will prevent the network from processing any further requests, simulating a problem with the network connection. If you see a job that requires a significant amount of resources, stop the job or turn off your computer.
Review your network system’s original specifications. Make sure the maximum load has not been exceeded and the correct type of wires and software are in place. These items may not cause network issues on a small network, but as the network expands, there is no longer any ability to manage these issues, resulting in a performance issue.
The most common suggestion to quickly resolve a network connection problem is to turn off your computer and turn it back on. This process ends any existing connections or work and requires the computer to reconnect. This might solve the problem temporarily, but it’s never a long-term solution.
Resetting the router can resolve many network connection issues.
