While streaming, the Unraid server shows as uploading ~90Mb/s with spikes up to 120Mb/s. I even tried directly mounting the samba mount from unraid onto Kodi and it even buffers then. I have tried the Plex app for Android, I have also recently played around with Kodi and it’s various add ons for Plex (Plex for Kodi, Composite, and PlexKodiConnect) and the issue always seems to be present. So the issue is that when I am streaming one of the higher quality 4k remuxes (~80Mbps for 4k hdr + ~5Mbps for lossless audio) I am constantly running into buffering issues even though I am not doing any transcoding.

It is wired directly to the Orbi router that has wireless backhaul to the other 2 satellites. Not the usual thing to be on this forum, but hey you guys are a knowledgeable bunch and this has got me stumped.
