I added Ethernet to a streaming stick that doesn't even have an Ethernet port
The 2025 Roku Streaming Stick Plus gives you an HDMI plug on one end and a USB-C port on the side. That is the whole list. Streaming sticks skip the Ethernet jack to stay small and cheap, and most buyers never miss it, though the omission stings if you spent a weekend pulling Cat6A through your own walls. Roku does support wired networking on its 2025 sticks, using that same USB-C port and an adapter that runs about $15. Nothing on the box mentions it. My office is the room where I stopped treating that as a curiosity, because wiring a TV instead of trusting Wi-Fi solves problems that no router upgrade touches.
