Ethernet over Wi-Fi is the non-negotiable baseline of network optimization for live streaming. The principle is structural: Wi-Fi shares bandwidth, suffers interference, and re-transmits dropped packets. Ethernet does none of those. Every working streamer with a stable broadcast runs ethernet.

The exception list is empty. There is no streaming context where Wi-Fi is the right choice. Streamers on laptops where ethernet seems impractical can run a USB-to-ethernet adapter for under 20 dollars. Streamers in apartments where the router is far from the streaming PC can run a long Cat6 cable along baseboards. Streamers in rooms without nearby ethernet drops can run a powerline-ethernet adapter (less ideal than direct ethernet but still better than Wi-Fi).

The implementation: identify the obstacle to ethernet in your current setup, solve the obstacle once, and run the cable. The 30-minute installation produces a quality lift that compounds across every stream for the rest of your career. Wi-Fi streaming is leaving the best single fix on the table. Run the cable.
