In the age of wireless everything, wired Ethernet remains the gold standard for stability — especially when streaming in 4K HDR. If you’re tired of buffering or weak Wi-Fi signals, the Roku Ultra (2022) offers a rare and powerful solution: a built-in Ethernet port.
In this guide, we cover the benefits of Ethernet on a streaming box, show how Roku Ultra compares to rivals like Fire TV and Chromecast, and offer setup tips for optimal performance.
Why Choose a Streaming Device with Ethernet?
Wi-Fi is convenient but often inconsistent — especially in homes with multiple users, thick walls, or wireless interference. Ethernet brings:
More consistent download speeds
Reduced buffering and faster start times
Better performance for Dolby Vision and Dolby Atmos
Improved gaming (for cloud-based apps)
Roku Ultra’s Ethernet Advantage
The Roku Ultra is one of the few mainstream streamers to include native Ethernet, eliminating the need for adapters. Features include:
Full 4K Dolby Vision + HDR10+ support
Dedicated Ethernet LAN port for wired networking
Dual-band Wi-Fi backup in case Ethernet is unavailable
How to Set Up Ethernet on Roku Ultra
