Wi-Fi vs Ethernet Basics

Contrast the media

Ethernet uses a cable between your device and a switch or router. Wi-Fi uses radio between your device and an access point. Both can carry the same IP traffic; the difference is the local link.

Weigh everyday trade-offs

• Ethernet: usually more stable latency and fewer neighbors on your link
• Wi-Fi: flexible placement, shared airtime, sensitive to walls and interference
• Both: still need correct IP, DNS, and gateway settings

Improve Wi-Fi when needed

Move closer to the access point, reduce obstacles, prefer 5 GHz or 6 GHz when the signal is strong enough, and avoid microwave ovens or crowded channels when troubleshooting slow Wi-Fi.

Use Ethernet for tough jobs

Large downloads, video calls, and latency-sensitive games often feel better on a wired link. A short Ethernet cable to a nearby switch or mesh node can isolate whether Wi-Fi is the bottleneck.
