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.

🔴 Link Plus (L2) – Solid Red LED

A solid red LED on the Link Plus Hub usually indicates a network communication issue rather than a hardware fault.

For the Link Plus to work correctly, the LED should display a solid green light, which confirms the hub is online and successfully connected to your network and Lightwave servers.

Many red LED issues are resolved simply by restarting the router first.

⚠️ Most Common Cause – Router / Startup Communication Issue

This commonly happens after:

  • A power cut

  • Restarting your broadband equipment

  • The router and Link Plus starting up out of sync

Sometimes the router fully boots after the Link Plus attempts to connect, causing the hub to remain red.

✅ First Step (Usually Fixes the Issue)

Restart Your Router

  1. Turn your router off

  2. Wait 30 seconds

  3. Turn the router back on

  4. Wait a few minutes for the internet connection to fully return

Once the router is back online, check the Link Plus Hub.

✅ A solid green LED means the hub is online and working correctly.

🔄 If the Link Plus Is Still Red

Restart the Link Plus Hub:

  1. Unplug the Link Plus power cable

  2. Wait 10 seconds

  3. Plug it back in

  4. Allow a few minutes for reconnection

🔁 Still Red? Restart Both Devices Together

If the issue continues:

  1. Turn off both the router and Link Plus

  2. Turn the router back on first

  3. Wait until the router internet connection is fully restored

  4. Plug the Link Plus back in

This usually resolves startup communication problems.

🌐 Network Setup Issues

If your Link Plus is connected through:

  • A network switch

  • A Wi-Fi extender

  • A mesh system

  • An access point

…it may struggle to maintain a stable connection.

✅ Recommended Fix

  • Connect the Link Plus directly to your main router using Ethernet

  • Check whether the LED turns green

  • If successful, restart or check the additional network equipment before reconnecting it

🌍 Router or Internet Provider Changes

A solid red LED can also occur if you have recently:

  • Changed your router

  • Switched broadband providers

  • Updated network settings

✅ Try the Following

  • Use a different Ethernet port on the router

  • Restart the router

  • Restart the Link Plus Hub

✅ What LED Colours Mean

  • 🟢 Solid Green = Link Plus is online and connected correctly

  • 🔴 Solid Red = Network communication issue / offline
