Wi-Fi streaming is the second-most-expensive mistake and the most preventable one in the entire stream-quality category. Every issue covered in Module 5 traces back to Wi-Fi being the wrong choice for live broadcasting, and the fix is a single ethernet cable.

The streamers who insist Wi-Fi is "fine" usually have not run the controlled comparison: stream once on Wi-Fi, then stream once on ethernet, with all other settings identical. The frame-drop comparison and the viewer-side stream stability comparison are not subtle.

The exceptions list remains empty. Streamers in setups where ethernet seems impossible can solve every constraint: long Cat6 cables along baseboards, USB-to-ethernet adapters for laptops, powerline-ethernet adapters for rooms without drops. None of the solutions are expensive. None of them take more than an afternoon to install.

The streamer who continues running Wi-Fi after reading this lesson is choosing to leave quality on the table. Run the cable. Run the test. The result speaks for itself. Move on with a stable foundation.
