“Why Joining Two Ethernet Cables With a Coupler Is Rarely the Best Fix” — what this page in the network covers. When an Ethernet cable falls short, the temptation to join two cords with a coupler is understandable—but networking experts say it’s rarely the best move. Couplers can introduce signal loss, add points of failure, and degrade performance, especially on high-speed connections. Instead, they recommend using a single longer cable, a proper switch, or a powerline adapter to extend your network reliably.
The issue matters because weak links in physical cabling can cause intermittent drops, slower speeds, and frustrating troubleshooting. For most homes and offices, a well-made Cat6 or Cat6a cable of sufficient length is cheap insurance against these problems. If you must connect two cables, ensure the coupler is rated for your cable category and keep total length under 100 meters.
