Simple DIY setup for CAT5E run caps up to 100mbps
Hi, from the title it seems I have some basic networking experience. I attempted to set up Ethernet at home using a 5E-rated outlet. I purchased a 25m CAT5E cable from Amazon and ran it through a conduit. After connecting it to a plugless outlet, my PC reached speeds around 100Mbps (typically 92-96Mbps). When trying to connect directly to the router, I got up to 1000Mbps, suggesting there might be an issue with the outlets or the cable itself. I’ve attached photos of the outlets and the cable markings. The cable is shielded, and I wasn’t sure how to handle the extra ground wire and metallic film, so I cut them off at both ends. Please help if you can!
From the image of the socket it appears only half of the wires are connected to the pins, and at least one pin seems quite damaged. It might be wise to purchase a budget Ethernet cabling kit, attach a header to the Ethernet cable you installed, and test whether it functions properly. If it works then the issue is likely poor installation in the socket or a damaged socket itself.
100 meg Fast Ethernet requires only two out of four pairs to function, whereas Gigabit and 2.5 gigabit need all four pairs. Likely the issue is with the termination. Cables might not be fully inserted or the color codes could be mismatched at one end or the other. Sometimes, if you're crimping those pass-through "EZ RJs" and your crimper blade is dull, the ends can get crushed instead of cut cleanly. Would you like to share a photo of the termination side of the keystone jack?
The feedback indicates your connection speed is capped at 10/100 instead of the full potential. This is likely due to the keystone jacks you selected or how the CAT5E cable was connected. A photo of both ends would help us diagnose better, or you might try reconnecting the cable to the keystone jacks.
All wires are secured correctly, yet one connection matches the A cabling layout while the other aligns with B. This causes two pairs to intersect while the remaining two remain straight. No device can maintain accuracy because every pair switches simultaneously with Auto-MDIX.
Thank you for the feedback. Initially, I assumed the cabling was either excellent or faulty. The realization that only two pairs would result in 10/100 was crucial. One cable broke near the plastic holder in this toolless RJ45 setup. I’ve completely reworked the connection and am now achieving full bandwidth. Appreciate your input.
