I have a standard starlink dish v2. I am using a starlink ethernet adapter to connect it to a TP Link ER 605 router. I have cable connected an EAP 225 Outdoor access point to it. I have also setup a captive portal on a wifi using the Omada software controller.

I need to extend this wifi (with the captive portal) to the whole 3 floor building, and also to a building just across the street(opposite to our building).

Can I acheive this by using a combination of TP Link M4 or M5 mesh routers and access points or I just need to get more of the same EAP 225 access points and use them in mesh mode
