I recently switched from Comcast to Century Link.
The Airport Extreme had to be setup again.
Remoter no longer works.
I unregistered and re-registered. I have quit RemoterFusion, Remoter and restarted the computer several times. I have powered the Airport Extreme down for several minutes.
I noticed that the external IP changed.
Now the Connectivity test fails.
I tried the instruction "Connecting Remoter to a computer inside
your home LAN from the Internet:" but it is apparently way out of date.
Neither Airport Utility 5.5.3 or Airport Utility 6.1 work as indicated.
