If your Roku viewing experience is interrupted by frequent pauses to rebuffer, or if you have poor video quality on channels like Netflix that use adaptive bitrate streaming, one obvious cause may be a slow download speed on your Roku device. The free Speed Test private Roku channel can help you diagnose a slow WiFi connection between your wireless router and your wireless Roku device.
Even though your Ethernet-connected computer may be receiving the Internet bandwidth that you're paying for, WiFi speeds to your Roku device can be slowed by the Roku's distance from your wireless router, physical obstacles between the Roku and the router, or by electronic interference. The Speed Test channel lets you test your Roku device's Internet dowload speed. For more information on this channel and using it to troubleshoot Roku connection issues, visit the Speed Test private channel page on RokuGuide.com.
