Troubleshooting: My Link Plus (L2) is Red

This article helps you diagnose and resolve the issue when your Lightwave Link Plus (L2) hub displays a red light. It provides clear troubleshooting steps to identify connectivity problems, restore normal operation, and ensure your smart home system is functioning correctly.

A Red LED on your Link Plus usually means there's a connectivity issue to the Lightwave server. Don’t worry—here’s how to troubleshoot it:

1. 🔄 Changed Your Internet Service Provider (ISP)?

If you’ve recently switched ISPs, your Link Plus might need time to adjust to the new network.

Try this:

  • 🔌 Plug the Link Plus into a different Ethernet port on your router (each port may have different firewall rules).

  • 🔁 Swap out the power and Ethernet cables in case one is failing

  • Restart your Link Plus by unplugging it and plugging it back in after 30 seconds 

❗ If it’s still red, contact your ISP (Internet Service Provider) to check if the Link Plus is being blocked by the router’s firewall.

2. ⚡ Had a Power Cut?

Power outages can disrupt the Link Plus’s connection.

🔧 Fix it by:

  • Restarting your Link Plus by unplugging it from power, waiting 30 seconds and plugging it back in
  • Waiting a couple of minutes to see if the light returns to green.

3. 🛠️ Still Not Working?

If you're still seeing the red light after trying the above steps, there might be an underlying issue.
