Why can't the Xiaomi Robot Vacuum 5 Pro connect to the network?

If the Xiaomi Robot Vacuum 5 Pro is unable to connect to the network, please refer to the following information:
1. Confirm whether the Wi-Fi password entered when connecting is correct. The Wi-Fi username cannot contain Chinese characters or special characters such as @¥% in the password setting. If so, please reset it to English or an account and password with numbers or letters and try again.
2. Check whether the router's external network connection is normal. You can try to open a web browser on your mobile phone or a computer connected to Wi-Fi to see if it is smooth.
3. Confirm whether the distance between the router and the robot is too far (outside the range of 5 meters or if there is a wall in between. You can try to move the machine within 1-2 meters of the router and try to reconnect.
4. Try connecting to the mobile phone's Wi-Fi hotspot.
5. Check whether the router is connected to too many smart devices, causing the network to slow down or the router to be unresponsive. You can restart the router and try again.
6. Currently, the device does not support company EAP802.1x certified networks, 5 GHz signal networks, or public Wi-Fi networks that require web authentication. You need to switch networks again and try to connect.
7. After the network is disconnected, if the device does not reconnect within 1 hour, the Wi-Fi module will disable its network connection function, and the Wi-Fi indicator will start flashing. The connection can only be restored after restarting the device.
8. Check whether the mobile phone has restricted the Xiaomi Home App's permissions, such as network access and location. Please allow these permissions and try again.
9. Connection failures can also be related to the phone model. Try connecting with another phone of a different model.
10. If you are still unable to connect to the network, try resetting the main unit and then reconnecting.
