Archer AX55(US)_V1.6_1.3.2 Build 20240325

1.) How do I ensure ethernet backhaul is being used for this configuration?

2.) Starlink,I have eithernet adapter and wish to have the backbone between the three devices wired, not wireless. with that said, what is the best configuration, should I bypass?, can their v2 router be used as a access point still? If not, can I remove the starlink router and just go eithernet adapter to TP-link?

3) Ideally i would like to use all three devices and have one mesh

Thank you in advance.
