Password manager for pre-shared keys
It would be nice if your wireless solution had a password manager for pre-shared keys. Whenever I enter the pre-shared keys while configuring a wireless network, the passwords are obfuscated. There's actually no way to display them afterwards. If I forget the password (and didn't store it elsewhere), there's no way other than selecting a new password, which has the side effect of disconnecting wireless clients.
Therefore I suggest you implement a password manager. The idea is you display all wireless networks with obfuscated passwords in WebAdmin and add a button to display the passwords in clear text. In the following prompt, you will then have to enter a very strong master password.
