@Charles_Andre I have the exact same issue. Main Deco X50 is showing 100% CPU and satelite Decos show disconnected even though they are wired and have green indicator lights. The mobile app is consistent in how bad it is at showing accurate information and the direct IP web interfaces are even worse. I've updated everything to latest Firmware versions but still have the issue. Looking here for a possible solution before I replace all of it...

  @Charles_Andre wow so x50 shows more info about devices than x60. also some x50 have easymesh support. i feel so regret to go with x60 instead of x50. i was thinking x60 better......

I have exactly the same problem with my Deco X50 (without LTE) ...

satellites crash and reboot or the end devices lose the connection to the wifi.

the main deco shows a processor load of 100% (both in the MobileApp and in the web interface).

A quick solution would be more than appreciated.
