Hi there! I see you've just replaced your WiFi router and now your system isn't connecting to WiFi, specifically your LIFX app is having trouble connecting to the new router, right? Let's work through this together.

When you switch to a new WiFi router, your LIFX bulbs usually need to be reconfigured because they're still trying to connect to the old network settings.

Here’s a step-by-step approach to get your LIFX app and lights back online with your new router:

1. Confirm WiFi Frequency: LIFX bulbs work only on 2.4 GHz WiFi networks (not 5 GHz). Please make sure your new router's 2.4 GHz band is enabled and broadcasting.

2. Reset Your LIFX bulbs: Since the network changed, you’ll need to reset your bulbs to factory settings so they can connect to the new WiFi. The reset method varies by bulb, but commonly, you turn the bulb on and off 5 times with a 1-second interval, ending with it on. The bulb should flash to indicate it's ready to connect.

3. Reconnect Using LIFX App:
- Ensure your smartphone is connected to the 2.4 GHz WiFi network.
- Open the LIFX app, and go through the process to add the bulbs as if they’re new devices.
- Follow app prompts to connect bulbs to your new WiFi.

4. Turn Off Other LIFX bulbs During Setup: If you have multiple bulbs, try setting up one bulb first and power off others, to avoid interference during setup.

5. Restart Your Router and Phone: Before connecting, restart your router and reboot your phone to clear any temporary network glitches.

6. Check for VPN or Cellular Data: Disable any VPNs and turn off cellular data on your phone during setup as they can interfere with discovery and connection.

If after this the bulbs still don't connect, try deleting and reinstalling the LIFX app and repeat the setup steps. Also, ensure your router's firewall or advanced security settings aren't blocking device connection.

Would you like me to guide you through the bulb reset process in detail based on your bulb model?
