How to Tell Whether a Network Problem Is Your Device, Router, or ISP

Use a simple sequence to isolate where connectivity is failing.

Quick Answer

Test the affected device, another device on the same network, the router/local connection, and then provider service in that order.

Step by Step

  1. Determine whether the problem affects one device or every device on the network.
  2. Test the affected device, another device on the same network, the router/local connection, and then provider service in that order.
  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.
