Do LAN cables go bad?

While Ethernet is an extremely reliable and long-running technology, cables fail through wear (if you move them around) and over time. (Some homes were also wired long enough ago that they use an older standard of Ethernet cable that can’t consistently support gigabit Ethernet signalling.)

How do I know if Ethernet is working?

Follow the Ethernet cable from your computer to the device where it terminates — such as a hub, router or switch — and check the status lights on the device. A solid green light usually means a good connection, while a flashing green light, or amber light, indicates that there’s a problem.

How can I test my cable without a tester?

The only thing you can do is to check the connectivity pin-to-pin from one side to the other. Easiest way to do this is tightly coupling a sawing needle to the ends of a multimeter probe with the sharp side sticking out. And sticking the sharp point to each contact slot on the RJ-45 connector and test for continuity.

How do I test an Ethernet jack?

Test the jack for a signal. Insert an ethernet loopback jack or sniffter into the jack. It will detect the Internet connection and give you a proper display light if the jack is working. This is the easiest way to check whether an ethernet jack is working.

How do I know if CAT5E cable is running?

One of the interesting things about Cat5 and Cat5e is that they are virtually identical in their physical appearance. You cannot tell them apart based on thickness, color, or the material used. The only way to identify them is to look at the text that is printed on the cable and see for yourself.

How do I know if I have Cat5 or Cat6?
