The network configuration of the device fails, mostly because the format of the router name and password does not meet the requirements. Please exclude it as follows:

1. The router name and password only support the characters in the ASSIC code table, and none of them are supported, for example: Chinese or other countries’ characters

2. It is necessary to confirm whether the password contains spaces, for example, there are often spaces at the end that are wrong.

3. You need to confirm whether the first letter of the password is capitalized, because the input method will often capitalize the first letter by default, but the actual router password is not capitalized

4. The router name and password cannot be too long. The router name should not exceed 10 digits and the router password should not exceed 10 digits.
