Good morning. 
 

I am the proud owner of this WiFi system. But I do have some questions. So please just answer the question instead of suggestion other solution unless it's hardware based. 
 

when I go into connection an see how each of the mesh router communicates, it says that they are communicating wirelessly. So the main mesh router which are set to carry out the internet connection is delivering that internet connection to the others wirelessly. I do have a 1400 mbit connection but when connecting a pc to one of the other routers than the main one with a lan cable I am getting far from that connection. I've have tried to connect each of them with a lan cable through 2.5gb hub/switch and that does fix it LAN based but wirelessly I am getting the same speeds at I did before connecting each mesh router with a lan cable. 
 

when going into settings and see how the other communicate with the main it says it communicate wirelessly. 
 

is there any way to change this so all the nodes carry out a lan based connection so they all deliver just as good speeds as the main router or do I need another mesh system to be able to carry that out. What is very important is that all of the nodes needs to support at least 2 ports with 2.5gbits one for in and one for out. 
 

yours sincerely
