I've been using Plex on my iMac for a few years now.
Recently, I've started to run into a lot of buffering when trying to watch shows and movies. The show will play for a few seconds, and then buffer for a few minutes, before playing any more. Recently, it's also started buffering in the middle of shows as well.
I've got the Plex server on a 2019 3.6Ghz iMac with 16 GB of RAM, so should have plenty of horsepower. The media lives on an external SSD adn is streamed over WiFi to the Apple TV 4K. (Been thinking of trying to hardwire the Apple TV, but that would require plugging into the iMac and sharing the WiFi connection from the iMac via ethernet)
I've read all of the forum pots on Reddit, Plex forums, etc... and I can't seem to figure this out.
Anyone have any suggestions on how I can hopefully fix this?
