Same with my old school Chromecast audio, it needs to be rebooted constantly as it too somehow stops connecting to wifi. I used to use it with a toslink cable and got really good sound out of it using a DLNA server from my storage. Now I just use my TV (as a monitor) optical out since it is connected via ethernet. I can still use DLNA on it as well to play my music.
