I was disconnected from my Airport Extreme this morning, and had to follow some steps, then realized I was setting up a PPPoE connection from my MacBook, and not my router. Now I have a symbol in my Menu like this <...> except the dots are more in the middle. When I right click it is says "No PPPoE Configurations were Found", and "Open Network Preferences". Is there any way to get rid of this symbol? I've been through the preferences many times.
