Roku position relative to the router
- Who:
- you.
- How:
- move the Roku player closer to the router, reduce obstacles such as walls or cabinets and avoid placing it behind the TV.
- Result that matters:

- If it fails the same:
- rules out position; restart the equipment.
- Evidence to keep:
- the new position and the result.

What it means
Roku documents code 003 in two official guides: the Wi-Fi guide calls it "Can't update" and the update guide calls it "Update cannot be downloaded". In both, the cause is the connection: Wi-Fi signal too weak for the download, or a network that does not complete it. So the actions are moving the device closer, restarting router and Roku, using Ethernet and, if it persists, contacting the provider. The code does not point to a TV fault.
