WIFI work until I restart my SMARTQ7

[Roussillon thomas]

I use Wicd in my smartQ7 whitch is a MID with the 1.5.9-4 version
The stock Os use a version of Ubuntu for ARM .
The WM is LXFCE

First time I laught WICD all is ok, connecting to WPA whitout problems.
After a reboot, I could'nt laught WICD, I have a message saying 'Now starting Wicd Network Manager', during 2 sec the proc use 100% and nothing else.
When I try in to launcht it in terminal I have the following log :

user@mojo:~$ wicd-client --no-tray
Traceback (most recent call last):
  File "/usr/share/wicd/wicd-client.py", line 50, in <module>

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.wicd.daemon was not provided by any .service files

in etc/wicd I have several configuration files like
manager-settings.conf
wireless-setting.conf
I try to rename both in .old but no change

I look also in /usr/share/wicd/wicd a found nothing interesting.

in var/log/wicd i have a log of 0 bytes

I was hable to recover my wifi after flashing my firmware but loose wifi after a reboot.
I make this twice so I really think that is the rebbot of my SmartQ7 how done that.

After that I try to install 1.5.9-2 whitch is the last .deb I found.
Install is ok but I cannot connect to WPA (I'll looking for template)
After reboot I have the same symptom, cannot launch WICD

I post a message in a smartq board whith no issue at the moment :
http://www.smartqmid.com/phpBB3/viewtopic.php?f=14&t=243

So have you an idea for this bug ?
I would like trying the last version, but I don't know how to compil it.

Thanks for your help.
