Then, open the command prompt on the connected device and type “ping” followed by the IP address of the connected device or a website. Connect one end of the cable to a device and the other end to a switch or modem. The tester will usually show the length of the cable, any open circuit or short circuit errors, and if the wire pairs are correctly connected.Ī ping test is a way to check if the cable is transmitting data packets without any loss or latency. The tester will indicate if the cable is faulty or working. Connect both ends of the cable to the tester and turn it on. If the LED lights are blinking, it means that the cable is working.Ī cable tester is a device that tests the connectivity of the Ethernet cable. If the cable has LED lights, plug one end of the cable into a device and the other end into an active network port on a switch. Some Ethernet cables come with LED lights on the connectors that indicate activity.
If the cable looks fine, proceed to test it. Check the connectors at both ends for any bent pins or damage, as these can prevent the cable from working. Here are some ways to test Ethernet cables:īefore testing the cable, visually inspect it for any damage or wear and tear.
Hence, it is important to test if an Ethernet cable is working before using it to connect to devices. Ethernet cables are used to connect devices to a network and if they are not working, the network communication can be disrupted.
