@Natalie137 flats can be difficult firstly because they often have solid internal walls and when they dont there is a very high level of wifi interference from your neighbours networks. WiFi in either circumstance is not the best way to connect a playstation. Asssuming running an ethernet cable from tge hub to your sons PS isnt practical you may find that buying a powerline networking kit which uses thecflats mainsxwiring to carry the signal is a good second best.
