The RSSI value should be listed as one of four options "poor", "Fair", "Good", or "Great" (obviously these may translate differently in other regions. For normal behavior we recommend either "good" or "Great" signal. See if you can temporarily move the system closer to the router to improve this, let us know if this test has any impact on your problem.
some additional questions:
- Is this issue only with Internet Radio? or do you see the same symptoms with SPotify, Deezer, the music library, etc.
- Roughly how long does the audio play for before the music is interrupted?
Thank you.
