I recently changed the password on my WiFi AP. Using the 2.63 version of the data viewer (latest I could find), I read the configuration from the 500+, change the password, write it back, it says it's completed, but when I read the configuration, it's reverted to the old password.
Seems like last time I set the initial password (2 years ago?) I had to get the "secret" version of the Data Viewer program. Is this still the case?
