WiFi dropping signal on other devices when sons using PS 5.

When son uses PS5 The wifi seems to drop on other peoples devices like if my daughter wants to use Roblox. He's connected via Ethernet not on WiFi.

@SMD14 When you say drops off, do you mean that you are just not getting the wireless device speeds as before? What speed package do you have and are you sure that he is not connecting to download a new game or doing some online playing etc sucking all the bandwidth that the PS5 can get/take.
