Feature Request: Passphrase Field Validation in Web UI

[thienandangthanh]

Currently, the form passphrase field does not validate the length of the input when a WiFi network’s security is enabled. This can lead to issues when attempting to connect to a secure network with a passphrase that does not meet the required length.

Specifically, when a user enters a passphrase of incorrect length, the Access Point (AP) disconnects and attempts to connect to the WiFi network with the user-entered credentials. If the passphrase length does not meet the requirement, the connection fails. The AP is then created again, requiring the user to reconnect. This creates a poor user experience and delays the configuration process.

For instance, in WPA/WPA2 Personal networks, each wireless network device encrypts the network traffic using a 256-bit key. This key may be entered either as a string of 64 hexadecimal digits, or as a passphrase of 8 to 63 printable ASCII characters.

To improve the user experience and prevent potential connection issues, I propose adding validation to the passphrase field. This validation should check if the entered passphrase meets the length requirements for the selected WiFi network’s security protocol before attempting to connect.
