The short version
- 01Confirm the screen shows code 016 rather than an update or HDCP message.
- 02Run Settings > Network > Check connection and inspect Network > About results.
- 03Move Roku closer to the router or reduce obstacles for a comparison.
- 04Restart the Roku device and router using the shared connection procedure.
- 05Compare Ethernet if the Roku model provides a supported wired connection.
- 06Report the code and signal result if the same failure continues after the closer-position test.
Raw message
Error 016
Likely causes
- Roku's Wi-Fi signal is weak.
- Distance or obstacles interfere with the connection.
Start with the signal result
Roku's current connection table groups 016 with weak Wi-Fi signal. Run Check connection, then inspect Settings > Network > About. Roku describes Fair and Poor signal results as reasons to move closer or reduce obstacles. The code is a connection diagnosis, not an HDMI cable error.
Compare a closer position with the same network
The code-table remedy moves Roku closer and restarts Roku and the router. Our comparison keeps the network and content unchanged while reducing distance or obstacles. Record whether the signal improves; use the shared Wi-Fi article below for the restart and reconnection procedure.
Use a supported wired comparison where available
Roku's connection-test article offers Ethernet when the model has a port. Our recommendation is to retain the wireless and wired results for support. If signal is good but internet access fails, follow the related 009 internet branch rather than repeatedly relocating the player.
Sources and review notes
Checked on . Based on Roku's September 2026 connection table and signal-result guidance. Consistent comparison tests are editorial guidance. Ethernet availability depends on the model. Glitchary is independent of Roku.
