What to do if the Xiaomi Smart Air Fryer 4.5L has network connection issues?

If you are using the Xiaomi Smart Air Fryer 4.5L, however, it fails to connect to Wi-Fi. It can be due to improper operation methods or network issues.
For new devices that cannot connect to Wi-Fi, please follow these troubleshooting steps:
1. The Xiaomi Smart Air Fryer does not support 5GHz Wi-Fi. Check the Wi-Fi network to ensure it is 2.4GHz;
2. Verify that the SSID and password of the Wi-Fi are entered correctly. Avoid using special characters in the SSID or password. It is recommended to use English letters or numbers;
3. Ensure the Wi-Fi is not an authenticated network (e.g., hotel, mall, or campus networks). Such networks are not supported;
4. Check if the router has enabled MAC address filtering or other network restrictions like blacklists or whitelists;
5. Reset the air fryer's Wi-Fi and try connecting again. If the device remains disconnected for 30 minutes after being powered on, its Wi-Fi module will enter sleep mode and will need to be reset to reconnect;
6. Try connecting to a different network or use a mobile hotspot;
7. If the above steps fail, it is advised to request the after-sales service for further inspection.
For devices that were previously connected but cannot connect after a firmware update:
1. Verify the device is connected to a 2.4GHz Wi-Fi network, as 5GHz is not supported;
2. Check for correct input of the SSID and password, and ensure no special characters are used;
3. Confirm the network is not an authenticated Wi-Fi type (e.g., hotel, mall, or campus networks);
4. Investigate whether the router has enabled MAC address filtering or other connection restrictions;
5. Perform a Wi-Fi reset on the air fryer and reconnect it. If the device enters sleep mode (30 minutes after being powered on without connection), reset it again to retry;
6. Try a different network or a mobile hotspot;
7. Use the Mi Home/Xiaomi Home APP to manually add the air fryer and check if the APP can search for the air fryer;
8. If the device is detectable, the issue is likely due to the network environment. Continue troubleshooting based on the above methods. Apply for the after-sales service if the issue can’t be solved;
9. If the device cannot be detected, provide the Xiaomi Account and the time of the failed connection, and submit feedback in the APP.
