Troubleshooting a network router involves checking physical connections, settings, and restarting the router. Verify internet signal, cables, and wireless capability. If the problem persists, contact the manufacturer’s help desk.
Troubleshooting a network router is a process of elimination to determine what kind of problem is preventing the router from connecting various devices such as desktop or laptop computers to an internet signal. Network router problems can arise from improper physical connections such as Ethernet cables between the Internet modem and the router. Problems can arise if the router is not set up correctly and does not receive the Internet signal. Network settings on networked computers can also be incorrect. If all connections and settings appear to be correct, it is possible that the router itself is malfunctioning and needs to be replaced.
The first step in troubleshooting a network router is to make sure that the router is receiving and broadcasting an Internet signal. Start by looking at the lights on your modem and network router. Check the manual for both devices to find out which lights test for Internet connectivity. If there is no internet connectivity to your modem, check for problems with your internet service provider, also called your ISP. If there is an internet signal, check the network router light which sees if the router is broadcasting the signal.
When the problem seems to be with the network router, turn off all computers connected to the network, then turn off the network router itself. Wait a few seconds and turn on the router, then turn on the computers. This restart of the network router can restore the function of the router.
If the problem persists, check the cables from the Internet modem to the router. Users should also check the cables from the router to any devices physically connected to the network. Verify that the cables are installed securely. Check your router and modem manuals to make sure you are using the correct type of cables.
With all cables installed correctly, check to see if the problem is with the wireless capability of your network router. Open the network connections window on your computer to make sure your machine’s wireless capability is enabled. If the wireless router is enabled, check if the network is connected.
A network router that receives an Internet signal from a modem and broadcasts it to a computer may still register as not connected. Check your local area network, or LAN, settings to make sure the correct Internet protocol or IP address is set. The network connections window on the computer allows users to set the correct IP address for their particular router and particular ISP.
When a network router is properly connected and set up correctly and receiving and transmitting a signal, it is still possible for connected devices not to connect to the Internet. In this case, the problem may be with the router itself. Most network router manufacturers will have a help desk available, often via a toll-free telephone number, for advanced troubleshooting or to determine if the router is malfunctioning.
