Likely causes

  • CommonNew hardware needing initial configurationRouters don't come pre-configured for your specific internet connection and need setup.

What to do

  1. Unplug the modem from power, and if replacing an old router, disconnect it as well.
  2. Connect the new router's WAN/internet port to the modem using an Ethernet cable.
  3. Plug the modem back in first and wait about a minute for its lights to stabilize, then plug in and power on the new router.
  4. Connect a device to the router either via the default Wi-Fi network name printed on the router's label, or with an Ethernet cable for the initial setup.
  5. Open the manufacturer's app (most modern routers use an app-based setup) or browse to the router's default IP address, and follow the on-screen setup wizard.
  6. Set a new, unique Wi-Fi network name and a strong password, and set a secure admin password for the router itself, different from the Wi-Fi password.
  7. Once setup completes and internet access is confirmed on the test device, reconnect all other devices to the new network name and password, and check for a firmware update in the app before finishing.

When to call a pro

If your internet plan requires special ISP configuration (like PPPoE credentials or a specific VLAN, common with some fiber providers), your ISP's support line can walk you through the exact settings needed.
