What to do if the Xiaomi Robot Vacuum E5 cannot connect to the network?

If the Xiaomi Robot Vacuum E5 cannot connect to the network, please check the following troubleshooting steps:
1. Make sure the Wi-Fi password is correct. Wi-Fi usernames should not contain Chinese characters, and passwords should not contain special characters like @, ¥, or %; 
2. Check if the router's internet connection is working properly. You can try opening a webpage on your phone or a computer to see if the browsing is smooth;
3. Ensure the distance between the robot and the router is within 5 meters and without obstructions like walls. You can move the robot closer to the router within 1-2 meters and try again;
4. Try connecting to your phone's hotspot;
5. If too many smart devices are connected to the router, the network will be slow or unresponsive. Try restarting the router and then attempting to reconnect;
6. Some certain types of networks are not supported, such as EAP802.1x authentication networks, 5G networks, or public Wi-Fi networks that require webpage authentication. Please connect to a different network, and then try again;
7. If the network is disconnected, the Wi-Fi module will close the network connection function and the Wi-Fi indicator will blink. In this case, please restart the device and then attempt to reconnect;
8. Check if your phone has restricted APP permissions, such as network connection and location. Allow these permissions and then try again;
9. The phone model will also be related to the connection failures. Try using a different phone model to connect;
10. If the above information doesn't help, you can try resetting the main unit and then attempting to reconnect.
