I haven’t had a drop out, freeze or any glitch of any kind for at a year. A high quality streamer should shield you from that. Both of my Aurender streamers have some file space on them… I copied a bunch of my albums (2,000) onto it, in case of an internet outage. But haven’t used it in a year.
My iPad will not load sometimes because the internet is slow, but my streamer continues without any hesitation.
I’m just guessing you need a better streamer. Mine works from a wall wart wiFi extender and gives me reliable sound quality equivalent to my really good vinyl analog side without a glitch… ever.
