My gear: Auralic Aries Mini.
My findings: Music playback stopped all of a sudden; after a minute (or so) playback of the track that had been interrupted started de novo from the beginning. I immediately suspected WLAN issues and checked the event messages in my Fritz!Box router. And actually it read the following:
" 5-GHz band cannot be used for 1 min. because of check for higher-priority users (e.g. RADAR) on the selected channel (frequency 5.260 GHz)".
Further explanations can be found here.
Since Auralic advises users to make use of the 5 GhZ Band instead of the 2.4 GHz Band such interruptions might occur more or less frequently, at least in Fritz!Box based WLANs. Hope this information is helpful.
