Hi, 

I'm hoping this is a simple fix or just something I've missed.

I recently purchased a new 3 pack Deco x68 to replace my old Google Nest Wifi system. Initially it was great. Setup was a breeze and was up and running in less than 10min.

Since the new system has been up I have noticed that devices keep dropping off and saying they are offline, mainly smart devices like lights and plugs but also smart air conditioners and other appliances. 

This means that I am now unable to start these remotely or by using google home voice commands or automations as when the device is shown as offline these don't work. 

I was running my old google system for over 4 years and never had this issue. 

Any suggestions or advice greatly appreciated.
