Your Ethernet ports probably don’t support those maximum speeds. Mainstream desktops, laptops, modems, routers, set-top-boxes, smart TVs, and game consoles generally include at least one Gigabit Ethernet (1,000 Mbps or 1 Gbps) port. You may see Fast Ethernet ports (100 Mbps) on some budget devices to keep the cost low. Multi-Gig Ethernet ports (2.5+ Gbps) have become more common in recent years thanks to Wi-Fi 5, but Gigabit Ethernet is generally the most used wired connection in today’s devices.
