Frequently Asked Questions

What internet speed do I need for Roku streaming?
You need at least 1.5 Mbps for standard definition, 5 Mbps for HD (720p/1080p), and 25 Mbps for 4K Ultra HD streaming. Higher speeds provide better quality and fewer interruptions.
Why does Error 018 happen even with fast internet?
Network congestion, WiFi interference, router issues, or too many devices using bandwidth can cause temporary speed drops. The error appears when speed falls below HD streaming requirements even momentarily.
Is wired connection better than WiFi for Roku?
Yes, Ethernet connections are more stable and faster than WiFi. If possible, use a wired connection for the best streaming experience, especially for 4K content.
Can I still watch content with Error 018?
Yes, you can usually still stream in standard definition. The error only prevents HD streaming. Lowering your display settings allows continued viewing while you fix the connection issue.
How do I check if my router is causing the problem?
Test internet speed on multiple devices. If only the Roku has issues while other devices stream fine, restart the Roku. If all devices are slow, restart your router or contact your ISP.
