Hi tplink an tplink community

I am currently using tplink device to create a mesh network.

I having 2 topology below

1. Ax55 pro and c64

2. 2 archer c64 and RE315

I have established both topology in mesh network. And i realized

For topo 1. Definitely ax55 will be main router, c64 in satellite mode, we can not access to c64 in advanced configuration such as set a bandwidth etc

For topo 2. We can access to the first c64 as main router, the second c64 same as Topo 1 issue but for RE315 we are able to access in advanced mode via ip address is connected to the main router

Could someone please help me?
