Sure. But in /etc/rc3.d the order of the network related services is this:


So I've tried stopping all 5 services and starting them in the above
order, because they get started in the above order while booting. But
already the third service, 'network', fails and wlan doesn't come up.
If I nevertheless restart NetworkManager and NetworkManagerDispatcher
I can see the wireless network in question in nm-applet but can not
connect. I enter the pre-shared key password but it wouldn't connect,
it just gives back the password window.

If I reboot though the above 5 services are started in the above order
and everything works, wlan comes up and nm-applet can connect using
the same pre-shared key password.

So it seems to me that I need to do some additional steps manually to
completely reproduce what is happening at boot time. It just seems
impossible to me that I can not reproduce everything what is happening
at boot time, without actually rebooting but doing the same things
manually as root.

Any ideas where should I be looking for clues?

Thanks a lot,

Psss, psss, put it down! -
