RJ-45

Internet cable connector

RJ-45 is the standard connector used for Ethernet network cables—the rectangular plastic plug with eight pins that clicks into computers, routers, and switches.

The connector is slightly wider than a telephone jack (RJ-11) and won't fit in a phone port.

Check that the RJ-45 is fully seated in the port.
