I'm running 12.04 on my MacBook Pro 5,5, and my Wi-Fi is working fine, but I'm having problems getting it to scan automatically at startup time.

On first login I get a notification that I'm disconnected, and no networks are listed in the Network Manager tray widget, even though Enable Wireless is ticked.

If I go to the terminal and do a manual scan, Network Manager kicks in after a second or two, populates the list and connects automatically to a saved network if available.

$ sudo iwlist wlan0 s

I've run the following commands immediately after startup for diagnosing the situation

$ iwconfig
$ sudo lshw -C network
$ sudo lspci -nn | grep 0280

(output here)

I'm not an expert, but as far as I can tell the driver is loaded and everything is working, but Network Manager just doesn't start a scan without a kick in the behind. I've spent a lot of time searching around, but I can't seem to find anyone with the same issue. Anyone know how I can resolve this? Thanks in advance.

As I suspected, this was probably a problem with Network Manager, and not driver related. I installed Wicd as a workaround and removed Network Manager, and now everything is working perfectly.

If I try to reinstall Network Manager and remove wicd again, I will post the results here, in case the problem was a corrupt config file or something similar.
