Hello again,

Much appreciated your quick and useful reply, I would like to know if the speed with Wds mode will be more than the speed through wifi or I have to expect that the speed will be reduced , note that I  want to use only the ports of C80 and not the wifi 

I haven't opened the box yet of tp link C80 archer , I am also waiting for Asus ax53u that will be used as Aimesh with Asus ax86u pro so I said maybe tp link C80 can benefit from the aimesh to receive strong signal in case I arrive to make C80 work alongside with the main  router Asus ax86u via Wds

The idea is like the following :

Asus ax86 u pro = main router and also DHCP server.

Tp link C80 archer : to be connected wirelessly to Asus ax86u pro and used only its for ports to connect wired clients .

Asus ax53 u  : to be connected via aimesh with the main router to create a  full coverage for the entire house .

I also forgot to mention that I have tp link re550 , I was thinking in case the Wds bridge didn't work I may connect this tp link re550 wifi range extender - repeater ,  as I am doing right now to the main router wirelessly .

Then I connect tp link C80 archer to tp link re550 via Ethernet cable so like that Tp link C80 will get internet directly from Ethernet cable and of course I disable all DHCP servers and I leave only of the main router so I can control all clients via the main router .

Let me know if my solutions or my ideas so to speak are clear and possible to achieve .

But all depends on the speed I hope to get .

Thanks in advance
