Question

Network administration

As written in the title, advise a powerful Wi Fi router for an old 2x storey building. And is it possible to increase the power of the Wi Fi transceiver from 100mW higher with OpenWrt firmware.

Answer 1

and how are you going to increase the power of smartphones / laptops ??? before receiving a signal, you need to make a request from a device that is not as powerful as a router with a big antenna))).
2-3 ordinary routers will cover all your floors, but my advice is to pull the whistle before each one.
