Hello! I understand that your Calex Smart device is not pairing and not finding the network. Let's work through this step by step to get you connected.

First, could you please tell me a bit more about your situation?
- Which Calex Smart device are you trying to pair (e.g., bulb, plug)?
- Are you seeing any error messages on the Calex Smart app or on the device itself?
- Is your Wi-Fi network 2.4 GHz, 5 GHz, or a dual-band router broadcasting separate SSIDs?
- Have you tried resetting the device or the app already?

In the meantime, here are some common troubleshooting steps to try:

1. Check Wi-Fi Frequency Band: Calex Smart devices usually only connect to 2.4 GHz Wi-Fi networks. Make sure your router's 2.4 GHz band is enabled and your smartphone is connected to that same network.

2. Bring Device Closer to Router: Place your smart device and your phone close to your Wi-Fi router during setup to ensure a strong signal.

3. Disable VPN or Proxy: If your phone uses a VPN or proxy, disable it temporarily, as it can interfere with network discovery.

4. Restart Router and Device: Reboot your Wi-Fi router and power cycle your Calex device to refresh network connections.

5. Reset Device and Restart Pairing: Follow the manual steps to reset your device (often by toggling power on/off in certain intervals) and try pairing again via the Calex Smart app.

6. Pair via Access Point (AP) Mode: If normal pairing fails, you can try pairing your device by connecting your phone directly to the device’s temporary Wi-Fi hotspot, as described in the app’s manual.

7. Firmware Update for Router: Ensure your router’s firmware is updated to the latest version to avoid connectivity issues.

If you want, I can walk you through the reset and AP mode pairing process in more detail. Also, if you can share which steps you have already tried, I can adjust the advice accordingly.

Would you like me to guide you through the reset and pairing again now?
