What Is an Ethernet Connection?

Understand wired networking between computers, routers, switches, and other devices.

Quick Answer

Ethernet uses network cable for a direct wired connection and is often faster, more stable, and lower-latency than weak Wi-Fi.

Step by Step

  1. Determine whether the problem affects one device or every device on the network.
  2. Ethernet uses network cable for a direct wired connection and is often faster, more stable, and lower-latency than weak Wi-Fi.
  3. Change one setting or component at a time and test again.
  4. Record existing router/network settings before changing passwords, DNS, addressing, or advanced configuration.

If That Doesn't Work

  • Router menus, indicator lights, and terminology vary by manufacturer and internet provider.
  • Avoid factory-resetting a modem/router unless you know how it is provisioned and have the information needed to restore the connection.
