Can you please provide us with the hardware version of your Deco X55? This FAQ will help you find it.

 

Thanks

Hi, 
You can refer to the instructions below to troubleshoot if the main Deco is unstable.
Fix unstable connection when connected to the Deco network
 

Please confirm the following information if the same phenomenon persists.
  1. When the main Deco has a red light, please disconnect the main Deco from the modem and connect a PC to the modem via the same Ethernet cable. Do you have an internet connection on your PC?
  2. You can try to change the main Deco and check if it helps: How to Change the Main Deco Unit
 

Best Regards
