I have had it working flawlessly for two months now. The issue is NOT the ROKU hardware or software. It’s YOUR NETWORK ROUTER! Airplay is a tricky protocol. It’s NOT routanle and will not travel across subnets or different networks. So if you have some devices connected hard wired, some on wifi 2.4Ghz and other on 5.0 GHz your problems will Begin there. I also suggest that you turn on
first off make sure your router is using WPA2 AES Apple now defaults to WPA3 with routers that support it…and ROKU does not.
turn in UPNP plug n play.
bridge the 2.4 and 5Ghz networks.
If all else fails buy yourself a refurbished ASUS RC AT1750 router from Amazon
