Sorry, my problem is not the wireless connection, but the mobile connection.
I can't activate a mobile USB key on my GPRS or UMTS network, because :
1) nm-applet does not start
2) umtsmon starts, but seems not able to setup the ppp connection (I don't 
know why)
Instead, from kde 4 session, all is working, both umtsmon and nm-applet, but - 
again -
I can't tell the difference. As a consequence, I have to stick to Plasma 
(which I don't like)
If I want to go to the umts net.
