Hello, I have a big problem with my decos, I recenlty added a new x50 Deco v1 on my setup and after that, my 2 other x10 Decos keep disconnecting.

So my new Deco setup is this:

2nd Floor: 1 Main Deco X50 V1.2, firmware 1.4.5, in Router mode, 1 satellite X10 Deco firmware 1.1.7 via Wifi

1st Floor: 1 satellite Deco X50 V1, firmware 1.6.1, Connected to main via Ethernet

Ground Floor: 2 satellite Deco X10, firmware 1.1.7, on 2 Different rooms both connected via Wifi.

My previous working setup was:

2nd Floor: 1 Main Deco X50 V1.2 in Router mode,

1st Floor: 1 satellite Deco X10 Connected to main via Ethernet

Ground Floor: 2 satellite Deco X10 on 2 Different rooms both connected via Wifi.

So the change is the the addition of an X50 on 1st Floor via Ethernet and the relocation of 1 X10 to the 2nd Floor via Wifi.

Since I added the X50 on 1st floor and relocated the X10, the Ground floor Decos wont connect, normally those 2 x10s were connecting to 1st Floor Deco and everything was smooth but now are refusing to connect on the new X50, their led is blinking red and after some seconds they blink green for once and then red blinking again.

I have tried to bring them near the main deco, remove all the decos from my app one by one and add them again, they work when they are close to main but then they wont work when I put them on their place. 

The problem seems to be that the 2 x10 decos on ground floor cannot connect to the new x50 on 1st Floor but i really cant understand why, I have tried to bring them close to main deco from the deco app and force them to connect to first floor x50 but they lose connection when i do that and they do the blinking red and once green i described above, they want to connect to Main deco to work but my main deco is 2 floors above and its not normal, thats why i bought decos, to cover a large area.

Sorry for the long post but I really need your help!

Thank you.
