Does plugging a device into Ethernet make the internet plan itself faster?

No. Ethernet does not change the internet service supplied to the home. It can give a device a faster, lower-latency, and less interference-prone connection to the router, which may help that device use the existing service more consistently.

Which devices should use Ethernet instead of Wi-Fi?

Prefer Ethernet for fixed devices when consistent performance, lower latency, or faster transfers matter and a cable is practical. Wi-Fi is the practical choice for devices that move, guests, and places where running a cable is difficult.

What do I need to connect a device by Ethernet?

You need an available Ethernet or LAN jack on the router, an Ethernet port on the device, and a cable suited to the equipment’s speed range. If the device lacks an Ethernet port, a USB Ethernet adapter may be needed.
