Long shot. As it maybe software related rather than networking but thought I’d put it out and see if anyone has any advice.
LG smart tv OLED65C26LD
Unifi dream machine
Unifi in wall (IWHD) ap
Unifi u6 lite
Synology NAS running Plex media server
Plex app on smart tv
Ap’s are hard wired back to the dream machine.
Tv is connected via wifi.
Everything worked fine then the Plex app on the tv would randomly stop playing media (spinning circle) failed to play media.
Sat in the same room as tv with phone, iPad and laptop on same wifi would play content with no issues.
To fix, I could go into the Unifi app and find the tv and force reconnect. It will then play media again for a hour or so.
Plugging the tv in via cat5 also resolves the issues.
I experimented with band steering and locking to the closest ap ( the in wall) neither helped.
Plex subs pointed me to a network issue rather than Plex app as that works fine on other devices.
Does anyone have any suggestions to try
