Actually it seemed to work. The conditions of success are somewhat strange: sometimes I've to reboot and re-t!y so that the dhclient works, but... well. Well, so it worked, until today. I get this today: wl0: wlc_wme_setparams : no-clock On kernel 2.6.32, when I do iwlist scan then, the computer freezes fully. Really fully. The hardware crashes (RAM, CPU, etc.). On a 3.2.0 kernel, it doesn't, but wlan0 says that no scan possible as network not available. My laptop is a HP ProBook 6560b (LG652ET) Do you know such problem and any solution? Do you think it can be a hardware problem? I don't understand why my wifi would be locked, as I haven't done anything for that and I don't know how to achieve this. But I can try some unlock if you tell me the shortcut. Finally, a Debian Dev suggested me, a long time ago, a software to check locking and control locking of bluetooth/wifi hardware, but I don't remember it. Thanks for your help and I'm now more available to test and tweak if needed.
