One important thing to note about Wi-Fi range extenders (also sometimes called “repeaters”) is that most of them actually create a new Wi-Fi network when rebroadcasting your existing one. That network will have a new name (it’ll often be your default network’s name with an EXT appended at the end, unless you change it) and that means you’ll have to connect to different networks when in different parts of your home. While that’s a small tradeoff in return for improved internet connection, some will be more inconvenienced than others.
