I have a mesh with 7 deco units. In a particular part of this mesh i have a Deco X50 and a M9 Plus connecting to a gigabyte ethernet switch. The switch then connects to a BE25 which provides the internet connection.

But if i look on the App or on the web page - it shows me that the the connection is BE25 -->Deco X50 ---> M9 Plus.

If i disconnect one of these i get nearly 400Mb/sec - if both are connected i get just 90Mb/sec when i do a sped test that this is connected to the M9 Plus.

Although they are both on the same wired Ethernet gig switch why do i get this kind of connectivity?
