I have set up a sd card which runs plex, retropie and pihole. For some reason when I run iton the 3b+ any files streaming through plex or the samba they will stutter and pause or bufer. I get fast speeds to transfer files over samba, 10 MB over ethernet.
Whereas if I run the same sd car d on the original 3b over wifi it runs perfectly without stuttering or anything.
Does anyone have any ideas how I could fix it on the new 3b+ or if there is some incompatibility?
