The speed of your Ethernet network will vary depending on the hardware you have connected to it. Most routers and switches provide up to 100 Mbps or 1,000 Mbps connections. If you’re simply using your router for Internet access, the 100 Mbps router should work fine, since most broadband connections are under 100 Mbps. If you share media between other computers on your network, or have a higher speed Internet connection, the higher speeds are recommended.
