AirPort: Link Down on en1. Reason 4 (Disassociated due to inactivity) This is the log entry I am getting when my macbook randomly disconnects from my network. My airport extreme is still up and running, as my phone is still connected, but the macbook has lsot connection. The only way I can fix this is to reboot, something i have done almost every day for about 2 months now. Does anyone know what this error is ? Griff.
