The benefit of this device is if your room or the place you are in is far from the modem or router. You connect this device between you and the internet source, and it boosts the signal, making the internet stronger and faster. There is an Ethernet port, but it is broken because the manufacturing is not strong, and even if you buy a new one, it won't last long, and the port will get damaged. So, it's only for wireless connection, like for mobile phones, iPads, laptops, PlayStations, or even PCs if their connection is wireless. For any inquiries, send a private message.
