Hi, I am connecting a new X60 to my network in a AP mode. The main one is connected using an Ethernet cable to the my home wired Ethernet backbone. The other 2 deco X60 are in different locations in the house. 
 

connecting the other 2 also with Ethernet cable to the backbone, make the whole network stuck. When they are connected wirelessly, it works fine but not reaching the maximum speed.

my question - isn't it supposed to work better when connecting each of the x60 to the backbone with cable?
