Your Roku streaming device may fail to connect to Wi-Fi, show "Not connected" status, buffer constantly, or lose connection during streaming. This prevents you from watching content on Netflix, Hulu, Disney+, and other streaming services.
Wi-Fi signal too weak: Roku may be too far from the router.
Router issues: Your router may need a restart or firmware update.
Incorrect Wi-Fi password: The saved password may be wrong after a router change.
Network congestion: Too many devices on the same network.
Roku software outdated: Old firmware can cause connectivity issues.
DNS or IP conflict: Network configuration issues preventing connection.
• Unplug your Roku device from power.
• Unplug your router and wait 30 seconds.
• Plug the router back in and wait for it to fully start.
• Plug your Roku back in and try connecting.
• Go to Roku Settings > Network > About.
• Check "Signal strength" — it should be Good or Excellent.
• If it's Poor or Fair, move your Roku closer to the router.
• Consider using a Roku with an ethernet port or a Wi-Fi extender.
• Go to Settings > Network > Set up connection > Wireless.
• Select your network and re-enter the password carefully.
• Make sure you're connecting to the correct network (2.4GHz vs 5GHz).
• Go to Settings > Network > Set up connection.
• Choose your network and enter the password.
• Under Advanced Settings, set DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
• Go to Settings > System > System Update > Check Now.
• Install any available updates.
• Restart Roku after updating.
• Go to Settings > System > Advanced System Settings > Factory Reset.
• This erases all settings — you'll need to set up Roku again.
• Only do this as a last resort.
If Roku still won't connect, contact Roku support at roku.com/support. The issue may be a hardware Wi-Fi problem.
Q: Why does my Roku keep losing Wi-Fi?
A: Usually caused by weak signal, router issues, or interference. Try using the 5GHz band and moving the Roku closer to the router.
Q: Can I use Roku with ethernet instead of Wi-Fi?
A: Some Roku models (Ultra, Streambar) have ethernet ports. For others, you can use a USB ethernet adapter if supported.
Q: Why does Roku buffer even with fast internet?
A: Buffering can be caused by Wi-Fi congestion, ISP throttling, or the streaming service's servers. Try lowering video quality temporarily.
Q: Does Roku work with 5GHz Wi-Fi?
A: Most modern Roku devices support both 2.4GHz and 5GHz. The 5GHz band is faster but has shorter range.
