@BarryBatsapple Have you changed the LAN cable? Have u tried different LAN port of Deco? Your Main Deco is working properly? Are you using Eco Mode and QoS? Try disable both and try again on PS5.

@Sezai1 Have u changed the power adapter? Have u plugged the power adapter directly into wall socket? How much deco units are you using?

@Sezai1 Are you also facing Satellite Deco Units showing offline in Deco App? Like this....Because im facing this issue.

@David-TP Hi.....Kindly fix this issue or can i throw my Deco system into trash? I tried older version of Deco App and still same issue. Look Deco App is showing my phone and tablet is connected on...

@David-TP PLEASE HELP ME
