- Move the Roku closer to the router temporarily to confirm signal strength is the issue.
- Re-enter the Wi-Fi password carefully, double-checking capital letters and symbols.
- Confirm you're connecting to a 2.4GHz network name if your router broadcasts separate bands.

When to call a pro
If no streaming device or computer can connect anywhere in the house, the issue is the router or ISP service, not the Roku; contact your internet provider.
