Ethernet (Wired Connection)

What It Means

Ethernet is the wired local area network (LAN) technology that connects devices to routers and switches via physical cables, and it remains the most reliable and highest-performing way to connect home devices. Ethernet cables come in standardized categories: Cat5 (legacy, 100 Mbps max, avoid), Cat5e (1 Gbps at up to 100 meters, suitable for most modern home use), Cat6 (10 Gbps at up to 55 meters, 1 Gbps at 100 meters), Cat6a (10 Gbps at 100 meters, the current sweet spot for new installations), Cat7 and Cat8 (10 to 40 Gbps, specialty use). Most consumer devices have gigabit ethernet ports (1 Gbps maximum), which is faster than every Wi-Fi standard through Wi-Fi 6. Premium laptops and gaming PCs increasingly ship with 2.5 GbE or 10 GbE ports to match multi-gig internet plans. For Broadband Grade speed testing, always prefer a wired ethernet connection to isolate ISP performance from Wi-Fi performance, a speed test over Wi-Fi adds variable overhead that can reduce measured speeds 20 to 60% below the actual ISP delivery. If a wired ethernet speed test shows your full plan speed but Wi-Fi tests show much less, the problem is your router, Wi-Fi environment, or client device, not your ISP. Wired connections have effectively zero jitter, lower latency (typically 0.1 to 0.3 ms router to PC versus 1 to 3 ms for Wi-Fi), and zero interference from neighboring networks, making ethernet strongly preferred for competitive online gaming, professional video editing over cloud storage, and critical work-from-home use.
