: Unlike wireless signals that must penetrate walls and compete with interference from other electronics, Ethernet uses physical copper twisted pairs to deliver a consistent, direct signal.
: A wired connection typically delivers speeds much closer to your ISP's advertised maximum. For example, a 400 Mbps plan might deliver 395 Mbps over Ethernet but only 120–150 Mbps over Wi-Fi depending on distance.
: For gamers, "ping" is everything. Ethernet significantly reduces latency by avoiding the digital-to-analog translation and congestion inherent in Wi-Fi, providing real-time responsiveness.
