breez plus keeps disconnecting from wifi, have to reboot it constantly to get it back online

Diagnosis

The Cielo Breez Plus is designed as a low-power IoT device, which means its internal Wi-Fi antenna is relatively small and sensitive to interference. When the device frequently disconnects, it is usually due to "signal flapping" or a DHCP lease conflict. Signal flapping occurs when the Received Signal Strength Indicator (RSSI) hovers around the -70 dBm to -80 dBm threshold; the device stays connected for a while, but any minor electromagnetic interference (like a microwave or a nearby cordless phone) causes the connection to drop, and the Breez Plus fails to auto-reconnect without a hard reboot. Another common root cause is "Band Steering" on modern Mesh Wi-Fi systems (like Eero, Google Nest, or Orbi). Because the Breez Plus only operates on the 2.4 GHz band, a router that uses a single SSID for both 2.4 GHz and 5 GHz often tries to "push" the device toward the 5 GHz band for better performance. Since the Breez Plus cannot communicate on 5 GHz, the router eventually drops the connection entirely, leaving the device in an offline state until the power is cycled to force a new handshake.

How to Fix It

To stabilize the connection and stop the need for constant reboots, follow these precise configuration steps:

1. Open the Cielo Home app on your smartphone. Navigate to Settings > Device Info. Look for the RSSI value. If the number is -75 dBm or higher (e.g., -80, -85), the signal is too weak. Move your router closer or install a 2.4 GHz range extender within 10 feet of the Breez Plus.
2. Access your router's admin panel (usually 192.168.1.1 or 192.168.0.1). Locate the Wireless settings and disable "Smart Connect" or "Band Steering."
3. Create two distinct SSIDs. Name one "Home_Wifi_2.4" and the other "Home_Wifi_5". This prevents the router from attempting to shift the Breez Plus to the unsupported 5 GHz band.
4. Assign a Static IP address to the Breez Plus. Find the MAC address of the device in the Cielo app and enter it into your router's DHCP Reservation table. This prevents the device from disconnecting when the router refreshes its IP lease.
5. Perform a clean reset: Unplug the Breez Plus from the USB power source, wait 30 seconds, and plug it back in. Re-pair the device specifically to the new 2.4 GHz SSID.

If That Didn't Work

• Change the Wi-Fi Channel: Log into your router and change the 2.4 GHz channel from "Auto" to a fixed channel. Use only channels 1, 6, or 11. Overlapping channels cause packet loss that triggers the Breez Plus to disconnect.
• Update Firmware Manually: If the device is online briefly, go to the app settings and check for a firmware update. If it's stuck, perform a factory reset by holding the pairing button for 10 seconds until the LED flashes rapidly, then re-add the device to the app.
• Check Power Supply Stability: Ensure you are using a high-quality 5V/1A USB power adapter. Using a low-voltage USB port on a TV or an old phone charger can cause the Wi-Fi chip to brown out and reset during high-power transmission bursts.
• Disable WPA3: Some older versions of the Breez Plus hardware struggle with WPA3 security. Switch your router's security mode to WPA2-PSK (AES) to ensure maximum compatibility with the device's network stack.

Heads Up

• Avoid placing the Breez Plus directly behind a metal AC chassis or inside a closed cabinet, as this acts as a Faraday cage and severely degrades the RSSI.
• If you use a VPN on your phone, disable it during the initial pairing process, as it can interfere with the local discovery of the Breez Plus.
• Keep the device at least 3 feet away from other high-power electronics or large mirrors, which can reflect and distort the 2.4 GHz signal.
• Periodically check the "Device Info" section in the app; if the RSSI drops below -70 dBm, you will likely experience intermittent connectivity again.
