There are three major categories of problems with network cable: accessibility issues, efficiency issues, and consistency issues. If your network link has stopped working and you believe a broken cable connecting you to an Ethernet network can affect it, there have been three simple checks you can do to see if the ethernet converter is the issue.
Connectivity problems are typically triggered by a malfunction on either end of a cable or by its connections. A simple test for the compatibility verification is to plug the suspicious cable into another machine or network device’s network connector. The socket you connect into the cable usually is part of a network adapter that offers the interface between that and a computer or network and the internet cable. Network adapters typically have fewer than two LED lights that indicate that there is an existing link and that transmitting operation is taking place on the cable. A network connection is shown by the Link LED of the network adapter. The Link LED will either turn on or start blinking to show a contact has been made after plugging the cable into the network adapter. If the LED does not light up or illuminate, either the cable or its attachment, or even both, is likely to have a malfunction.
If you have a performance problem, the network link crashes occasionally or transmits data at even slower velocities. A broken or twisted cable usually causes output issues. Although you can normally straighten a bent cable to fix the problem, a broken cable may need to be replaced. Check the length of the cable manually to figure out how to solve the performance problem and search for any sharp twists, kinks and perhaps other physical defects in the cable. Cable installations, such as those where the cable is behind a layer of brick, will require you to get additional support. However, if you notice a sharp bend or kink in the cable, loosen the wire and verify if it solves the problem. Swing the cable gently at the socket side-to – side before actually removing the wire, to see how the connection can be restored. If so, the fault lies with the connector, meaning you can patch or remove the entire cable. If all of these checks do not solve the issue, the best bet is to substitute the cable with one that you know is fine.
Continuity issues may also be caused by a broken or split wire, a foreign object — like a pin, staple or bolt — breaching the wire, heavy electromagnetic interference or EMI, or some other physical harm or disturbance, including weak connections and bends in a cable. Where a visual inspection of the length of a cable is possible, search for either of these reasons. If the cable can not be physically tested, then test it with a continuity tester, an automated device designed for this purpose in particular. If the issue is EMI — or its relative radio frequency interference, or RFI — it should be defined as low continuity by a continuity tester.
