Why each option
Since both the wall jack and NIC passed their individual tests, the patch cable connecting them is the remaining variable, and a cable tester is used to verify that cable.
A toner probe is used to trace and locate cables hidden inside walls or cable bundles and does not test cable functionality or connectivity.
A multimeter measures electrical properties such as voltage, resistance, and current and is not designed to test network cable wiring or data continuity.
A wireless locator detects wireless access points and signal strength and is irrelevant to diagnosing a wired Ethernet connection issue.
A cable tester checks the physical patch cable segment running between the wall jack and the PC's NIC for continuity, correct pin mapping, and shorts, isolating whether a faulty cable is responsible for the connectivity problem.
