MacBook connected to ghost network I have a MacBook and it has been giving me a weird issue since today morning. I have a WiFi at home and when I booted up my laptop it showed connected to my Wi-Fi network even when the router was switched off.

I tried rebooting my laptop and turning the AirPort on and off, but I faced the same issue. It still showed connected to the wifi network that had been off for the past couple of hours.

The net did start to work when I switched on the router but I still can't figure out why this was happening.
You are actually connected to the AirPort.  Whether the router is up or down wouldn't matter, as your wifi will show the stats of your connection only to the AirPort device.
