Two comments: 1) when I had issues with wireless, they were not constant, they seemed to vary with wireless usage in the neighborhood (time of day/day of week). 2) there’s another Roon/microRendu interaction that has been discussed here and on Sonore’s forums in CA, regarding jumbo IP frames. I’ve not had this problem myself, but it appears that streaming can go wrong when something is using those larger IP frames: https://community.roonlabs.com/t/endpoints-work-via-airplay-but-not-raat-solved-jumbo-frames-were-enabled/15681/14
