Symptoms
Consider the following scenario:
-
You configure a mobile broadband connection that requires a password on a Windows 7 Service Pack 1 (SP1)-based computer.
-
You create a default profile for the mobile broadband connection, and then you set it to auto-connect.
-
You manually disconnect the computer from the mobile broadband network.
-
You restart the computer.
-
You try to connect to the mobile broadband.
In this scenario, the connection attempt fails because of an incorrect password.
Cause
This issue occurs because the profile is rewritten without the saved password after you disconnect the computer from the mobile broadband network. Therefore, the password is lost, and the attempt to reconnect to the mobile broadband network fails.
