I have bought fiio for several years and will continue to do so. I have also bought Astell and Kern and Pioneer and found fiio to be the best overall package. But your point is valid. The device has to be judged by how it was marketed and clearly stable WiFi is a prerequisite to meet expectations. My device is fine although I rarely need it as I don’t stream. Yours isn’t,others have the same issue,fiio should have sorted. And their customer service? Sometimes excellent,sometimes non existent and that is not good enough.
