WiFi is convenient. Ethernet is reliable. For many uses the difference doesn't matter. For some it matters enormously. Knowing which situations actually need wired saves a lot of troubleshooting time chasing wireless problems that have a much simpler solution.
WHERE WIFI GENUINELY FALLS SHORT
- Video calls and conferencing — WiFi's variable latency causes audio/video quality issues that a wired connection eliminates entirely.
- Gaming — Latency spikes on WiFi cause exactly the kind of lag that matters competitively. Ethernet eliminates this variable.
- NAS and file servers — A NAS on WiFi performs far below its capability. Wired is essentially mandatory for a NAS to be useful.
- Large file transfers and backups — Real-world WiFi rarely exceeds 50 MB/s. Gigabit ethernet delivers 100+ MB/s consistently.
💡 When troubleshooting internet performance on a specific device, connect it via ethernet as a diagnostic step. If the problem goes away, WiFi is the variable — not your internet service.
