Can a b43 device DO monitor mode? many only can do managed.

HI
Yea,I had managed to start monitor mode and scan with airodump as well then all of a sudden,everything's gone south

Okay. Try this.
Check /etc/modprobe/blacklist for anything mentioned melow. Put this line in /etc/modprobe.d/wlan or some other file of your choosing

install b43 /sbin/modprobe -i ssb; /sbin/modprobe -i b43; /sbin/modprobe btusb

Reason: B43 uses Sonics Silicon Backplane, and there's some stupid little driver tucked into the ssb module so the usb based b43 chip appears on pci. The btusb is for bluetooth, presuming your device does that.

HI thanks alot..just saw this am gonna give it a try and let you know.
I have just installed the 2.6.34 kernel and am having wireless probelms again..getting error System Error:InstallArchives() when I try to activte the proprietary driver.

You did read and follow the bit about firmware?
BTW, if you want good advice, answer the questions and keep us up to date.

HI
Yea I created a conf file wlan and pasted these(your earlier post) into it.I also blacklisted the wl driver in etc/modules too..but everytime i try to activate the b43 driver it gives an SystemError:Installarchive() and the bcmwl oackage fails too.
Yea I read about the firmware if you mean downloading new firmware with fwcutter?
thanks alot for your help
