Did the issue start ever since the 1.6.1 firmware upgrade? 

 

It has been occurring since the previous firmware and continues in the current one.

 

-Have you noticed any Deco turn red?

 

 No.

 

-How many online clients are connected to the Deco X50? Would there be some smart home devices 

 

20 Clients. ( 13 in the main and 7 in the satellite )
I have a robot vacuum cleaner, smart switch, lamp, TVs, air conditioning, pool heater.
 

By the way, is the satellite Deco X50 wirelessly connected to the main Deco X50 

 

It is connected wirelessly

best regards.

I disabled "Fast Roaming" and "Beamforming" and the problem persists.
 

In fact, the clients slow down but do not disconnect.

When I restart it, it starts again but in a short time it starts to slow down again, and every time it is slow I look at the graph on the APP and it is using 100% of the CPU.

Charles I have been delaying forever to change my Wi-Fi network. I have had an Ape Wi-Fi network for the past 15 years. Not a issue of a day. The only reason I eventually decided to change is because I was scared a device might fail and leave me without Wi-Fi. I researched a bit. Ended up buying X55 deco,s 8 of them us two outdoor x50's. I have exactly the same issues. This network is really bad, shows disconnected when it's connected and other way round. All my AP'S are cable connected. I can't believe the app, because it shows it's wifi connected but it's wired. Shows no one connected but I am. Not sure what support staff work for deco, but it's bad. Just in reading their response to you is concerning, no proper answers just giving you the run arround. 15 year old apple AP'S worked MUCH better. DECO Fix your issues or you will end up with all my AP'S to try and sell to some other looser. Can't believe new AP'S are so bad. 

Same Issue here with Deco X50 5G

please fix asap
