I tried both on a 32bit and a 64bit architectures (the first is frodo), and it works. I too see only CCK packets. On 64bit arch (Atom) it works but when I try to unload the module I get this [ 1117.516031] unregister_netdevice: waiting for wlan1 to become free. Usage count = 1 and the device is never release (by who?). I have to reboot. I'm using two cards, one reports [ 311.439406] b43-phy0: Broadcom 4321 WLAN found (core revision 12) [ 311.480046] b43-phy0 debug: Found PHY: Analog 5, Type 4, Revision 2 [ 311.480075] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2055, Revision 4 The other (an Apple original card) reports [ 82.726931] b43-phy0: Broadcom 4321 WLAN found (core revision 11) [ 82.768030] b43-phy0 debug: Found PHY: Analog 5, Type 4, Revision 1 [ 82.768062] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2055, Revision 4 Thanks, -Francesco Informativa sulla privacy: http://help.ing.unibs.it/privacy.php
