Most just use router mode. AP mode is used when you connect the router to another router or to a gateway (combo router modem).

  @ArcherC8 ,   That is exactly my question.  There is an ethernet cable that runs from my homes FIOS modem\router to the up stairs and the Archer 55 is connected to this.   Any reason not to keep the Archer 55 in router mode vs Access Point?

In router mode, the AX55 uses NAT for the LAN clients.  In AP mode, NAT is not used and the main network is simply extended.  Using the AX55 as a downstream router makes your network devices use double NAT which can cause problems on some devices.  If you are not having any connection issues, the router mode is fine and will also give you more control over your network.

If you decide to use the AP mode, most users disable the DHCP server and let the main router handle the network addressing.

I have security cameras with assigned DNS numbers in the 192.168.1.x range by the incoming Google Fiber Router.  If I let my AX55 be a router then it gets a new space assigned by my Google fiber router as 192.168.0.x and none of my cameras can be found.  Therefore I have to use AP mode.
