Hi guys,

I purchased and set up 3 * X75 around the house and its working great so far. I have the main deco connected to my 6-year old RT-AC88U router via LAN and the rest of the decos set up via app. 
 

I also purchased an Archer AX73 AX5400 Router, thinking that I needed to replace my old router
 

After some reading, I am led to believe that getting the AX73 may be redundant as the Deco's act as a router as well.
 

Will I get any improved performance by incorporating the AX73 into my home and if so, how would I go about configuring it and the Decos (AP/Router Mode)? 

many thanks for your help!
