WiFi on the Milestone – hmm, interesting…

The Milestone (and I suppose, Droid) has an interesting glitch in its WiFi code.

When trying to connect to a protected network with an incorrect password, the networking code does not notify the application that the password is wrong. It just sits there trying to connect – the final notification is that a connection is in progress, but no notification of a successful connect (obviously) and no errors.

The problem is deep inside the firmware. This can be verified with Android’s built-it WiFi connection screen.

My code registers for WifiManager.SUPPLICANT_STATE_CHANGED_ACTION (“android.net.wifi.supplicant.STATE_CHANGE”). It is broadcast in many cases, but in case there is an authentication error there is supposed to be an integer extra, WifiManager.EXTRA_SUPPLICANT_ERROR set to WifiManager.ERROR_AUTHENTICATING.

On the Milestone, the action is never broadcast.

HTC Hero handles this case the way it’s supposed to.

      Android doesn’t let application access network passwords for security reasons. You will need to change the password at the router (there is usually a web interface for this), then update the network’s password in the application.
