Change Nighthawk AX8 to access point in different OEM wireless router

[Gregs46]

I bought a second RAX 80 and want to convert it to an access point but I have an independent wireless Router TP-Link Archer C5400X. I read that having two Mesh Extenders would slow down access by users to a device or internet.

I am running Windows OS 10, (2) Netgear Nighthawk RAX80 AX8 with updated firmware to 1.0.1.70_1.0.2.

What's the process to enhance the second RAX 80 as AP through the TP-Link wireless router?

Try just putting it in access point mode and seeing how it does.

there's isn't much for optimizing it.
