Comment 4 for bug 816145

network-manager start/stop and kernel driver load/unload tested (syslog)
hardware button tested (syslog1)
rfkill checked (command 1)
Also, tried full instructions at Hotkeys/Troubleshooting in case it was the Hardware button itself. It was tested with udev and acpi_listen and there is no event for the button, so could be that the kernel is not initiating an event to NetworkManager or X to kick the wifi in.

Could try wpa_supplicant but need instructions on how to do this - any simple instructions welcome (WEP 64 hex key), i.e. how to kick it to connect manually, although I don't know the commands.

udev tested as per Hotkeys/Troubleshooting - no events for button

Mainline kernel amd64 v3.0-rc7 tested too, no change in the situation.
