How do I change the admin password on the WRE2206?

Go to Maintenance > System > Password in the Web Configurator. Enter your current password in the Old Password field, type your new password (up to 30 characters) in the New Password field, and re-enter it in the Retype to Confirm field, then click Apply. It is recommended to use a password consisting of different types of characters such as numbers and letters, and to write it down and store it in a safe place. (Page 46, 9)
