hi 

All my deco p9 are connected via power line and all of them connected network switch as well

I want to use ethernet backhaul , however network switch goes to loop protection mode. 

It must be all decos are connected to powerline and networkswitch via ethernet cable. 

When I disable loop protection,  I create a loop in network and , communication is not possible. When I enable loop protection on switch, all deco p9 are using powerline. Ethernet is not used. How to properly set deco p9 to let them use network switch instead of powerline. 

I m using latest firmware,  there is no update available when check update. 

Thank you very much.  

Best regards.  

Ps, I did setup once via powerline , then I moved my house wanted use cat5 and network switch to get better ethernet connectivity between decos instead of powerline.
