can i connect 24 port switch RBK20

[gtyers]

Would like to connect my RBK20 to TP link 24 port switch?

What setting do i need to change?

Yes. Unmanaged and non green ethernet is preferred. If it happens to be a managed switch, disable ALL IGMP procotols on the switch.

yes its unmanaged.

do i just run the orbi in router or AP mode. any other settings i need to change?

sorry for the stupid questions.

Depends. Do you have a router upstream from the RBR? 

What is the Mfr and model# of the ISP modem the NG router is connected too?

If you don't have any router upstream from the RBR, then the RBR can run in router mode with the switch connected behind the RBR and all LAN devices to the switch.
