1) use patch cord to ensure the devices are ok 2) look through the cable and check if it's tensed, compressed, constrained, twisted or turned with small radius. straighten it if required 3) remember the time and reliability is money and just replace itHowever, you have to physically connect it to your device for it to work, which raises the question: What happens if your ethernet cable is too long? You will experience a drastic drop in signal transmission if your ethernet cable is too long. A few extra meters might work with a diminished data. If an Ethernet cable exceeds its maximum recommended length of 100 meters (328 feet), the data signal weakens, a phenomenon known as attenuation. They consist of four twisted pairs of copper wires, each. Your connection speed and overall performance can suffer a bit if you use an Ethernet cable that's too long. Longer cables can introduce signal interference between devices, which can cause dropped packets, increased latency, and loss of data. I have a wac104 NETGEAR access point in my shed.
