Accessing Settings>mydlink will now display a summary of your
mydlink Service status and mydlink Account.
Note: After mydlink registration is completed, your router's default PPPoE
connection will be set to Always.On. If your ISP charges for usage,
you may wish to manually choose Dial.On.Demand as your default
setting, however, mydlink features may not work as intended.
