My home has both wired and wireless network. My wired network is approximately 20 connections utilizing an old Asus router with wireless turned off, and several gig switches. I am planning to upgrade the wired network with Omada router and switches. 

To go along with that, I would like to use an Archer AX21 for my wireless. It would go on the first floor of my home as just an access point, since the wired connections all terminate in the basement utility closet. 

Is this a good configuration? Im hoping wifi 6 on the AX21 would improve my wireless and reach at least the second floor of my home. 

Any suggestions would be appreciated.
