I recently purchased a house that already had CAT5E running to many rooms. I'm setting up my network but faced a minor problem. My router is in the basement near the Verizon ONT, and from one of its Ethernet ports I have a CAT6 cable going down through the floor to an under-stair closet. Inside that closet sits a gigabit PoE switch (TP-Link TL-SG1005P V2), which connects to the CAT6. From another port on that switch, the cable passes through the existing CAT5E in the house and reaches my living room, where it connects to my access point (TP-Link EAP235-Wall). All these devices support gigabit speeds, yet the access point only shows 100Mbps and the switch light is yellow. It seems the issue might be related to a wiring configuration. The cable runs through the house, with all connections at each end appearing fine. Could this be an A versus B wiring problem? I tested a short between the switch and the AP and got a full gigabit connection, suggesting the problem lies elsewhere—possibly the length of the wiring.

It might be a faulty cable, possibly due to incorrect pin configuration or a damaged wire. The best solution is to employ a cable tester to confirm the issue.

Yes, the tester passed all the wires with proper connections, showing a green light on each, indicating everything is functioning correctly.

Is this a smart probe? Will it accurately trace the wires and confirm the installer’s connections are correct? If you had room to stretch the cable, you’d simply retighten it yourself.

I think it's indicating that the connections are complete, but I'll adjust them again tomorrow. I've already secured other cables around the house with no ends, using the same CAT5E, and they're delivering full gigabit speeds, so it seems the ends might be faulty.

I reset both ends of the thread, which resolved the problem. Now it makes sense considering the original plug arrangement had the wires in the incorrect sequence.
