I am currently using Merlin 380.61. I have IGMP snooping enabled for my lan (under IPTV), and all three wireless bands (under advanced settings). Airplay will typically work for a bit and then no longer connect. Right now my symptoms have been very consistent:
- If I airplay from my phone over wifi to my apple tv (video) or airport express (audio), nothing will work.
- If I airplay from my mac over ethernet to my airport express (audio), it will work for about 7-10 minutes and then no longer stream. Not sure about video to my ATV.
