See the following image:
The current setup is the black part. Now I want to run a cable from the router to a relatively distant part of the house and place a device at the other end of the cable so that it extends the Wi-Fi network.
If possible, I want both devices to be part of the same Wi-Fi network so that phones, laptops, etc can roam seamlessly between them, without having to reconnect.
What type of device should I place at the other end of the cable? The router was provided by the ISP, I don't think it's anything special and I don't know how much the ISP will allow me to mess with the settings, so I understand that I may need to place another device next to the router.
