7 Main Reasons Why Picooc Won't Connect to Wi-Fi

Connection problems Picooc to the network are divided into two categories: software (failure in the application, firmware or router settings) and hardware (failure of the Wi-Fi module in the scale). The latter is extremely rare—less than 2% of cases. Here is a full list of possible causes:

• 🔌 Incorrect router settings: The scale does not support some types of encryption (eg. WPA3) or hidden networks (SSID).
• 📱 Outdated version of the application: in older versions Picooc App There is no support for new security protocols.
• 🔄 IP address conflict: the router assigned the scale an address that is already occupied by another device on the network.
• 📡 Weak Wi-Fi signal: if the router is located far away or operates at a frequency 5 GHz, the scales may not “see” the network.
• 🔧 Time synchronization failure: Incorrect date/time on your smartphone or scale is blocking the connection.
• 🔋 Dead batteries: When the battery level is low (<15%), the Wi-Fi module is disabled to save power.
• 🛠️ Firmware corruption: After an unsuccessful update, the scale may “forget” the network settings.

Before you start setting up, please check Wi-Fi indicator on the scale:

• Flashing blue — the scales are trying to connect, but cannot log in to the network.

• It's red - critical error (reset or firmware reflash required).

• It doesn't glow — the Wi-Fi module is disabled or faulty.

⚠️ Attention: If your router uses WPA3-Enterprise or 802.1X (corporate networks), Picooc won't be able to connect at all. The solution is to create a guest network with WPA2-PSK.

Configuring your router for Picooc compatibility

In half the cases, the problem lies in the router settings. Scales Picooc Only support certain Wi-Fi standards and encryption types. Below are optimal settings for most router models (TP-Link, ASUS, Keenetic, MikroTik and others):

To change settings:

1. Open the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section Wi-Fi → Security settings.
3. Set the parameters according to the table above.
4. Save changes and reboot the router.

If you have a dual-band router, disable network sharing (option Smart Connect or Band Steering). The scales should only "see" the network. 2.4 GHz with an explicit name (for example, MyWiFi_2G).

Updating and reinstalling the Picooc app
