Help Creating OneMesh Network WIFI

Job ID: 33714631

Budget: $10 – $30 USD

I need help from a TP-Link network expert.
I need to create a large network with a single WIFI name and password.
My router is an Archer VR600, seeing that it has the option to create a OneMesh, I bought two RE305. But I am not able to connect them to each other.
The most I have achieved is to use them as normal Access Points.
Thank you.
