Hello.

i am wanting to replace my Orbi and satellite with either the XE750 Pro or similar. 

set-up:  2 story house (approx 1200 sq ft):  upstairs; spectrum modem, Asus gaming router (two consoles attached by LAN) attached to modem and Orbi in AP mode attached to router and a switch attached with cable to the Orbi. Downstairs; Orbi satellite connected wirelessly.  We have close to 20-25 connections.

I do reset all equipment about every 2 weeks but the Orbi has been going offline several times in the last month.  (No firmware update available)

What is the best TP link for my setup?  
 

Thank you.
