Good morning,

Let me explain a little more about the setup :

I have my internet link terminated in an ASUS wireless router and an ethernet cable running from that device into the master P9 both of which are located side by side in my office. The other 2 P9 devices are downstairs at opposite ends of the house.The 2 P9  devices downstairs are fine - no connectivity issues, full ping response etc.

In the office, I now have to use the ASUS router wireless connection to work and this is 100% reliable. The issue with the master  P9 has started in the last 10 days and took a while to figure out. Basically the connection is intermittent, no ping response at times etc. No changes made to setup which may have introduced the change.

There is no reason to doubt the connection between the master P9 and Asus is unstable as both P9's downstairs are fine. For example, Netflix will run without any issue on smart TV downstairs using P9 downstairs, but I can't connect to master P9 at same time. To me it is an issue with master P9 - why does it not even reply to ping?

No red lights on any P9, all recently rebooted and mesh restablished with no issues (over powerline). The model is a P9(EU) Ver 1.

What do you hope to achieve by swapping the P9's? Is there some way to get elevated access to troubleshoot this issue? It is not an IP Address conflict issue as I have stepped through the entire IP ranges etc and there are no overlaps between devices / routers etc

I have attached 2 screen shots below from Iphone app showing network connectivity with IP Address, yet Deco App has just timed out (apologies for size of images!)
