Hi, it would be great to display the Mesh Backhaul Link speed between Decos but currently, this feature is still under consideration.
Currently, you could test the Ethernet speed from the satellite Deco and compare it with the Ethernet speed from the main Deco to check the Backhaul strength between Decos.
Personally, I think the wireless backhaul between Deco XE75 is over 2.4+5+6 GHz, unless these two units are far away from each other and separated from multiple walls or doors, the wireless backhaul might be better than the Ethernet Backhaul based on powerline adapters.
Thank you very much.
Best regards.
