Troubles setting up LHG LTE18 kit and wAP2nD

RouterOS Beginner Basics
1

I have an LHG LTE18 kit and wAP2nD.
I can connect to wAP admin ( 192.168.88.1 ).
But I can’t connect to LHG admin ( 192.168.188.1 ) - “Site can’t be reached”.
I expect both devices to connect “plug and play”.
Am I missing something?
