Today I was using this computer with boradcom4312 with b43 (for
14e4:4312) driver, in an environment there were 30~40 wifi hotspot,
some encrypted some not, all other win/mac can connect one unencrypted
wifi while my ubuntu 10.04 with this b43 driver cannot, all I know to
try is "modprobe -r b43" and "modprobe b43"; iwconfig/iwlist output
also seems good,
I post the pci data and dmesg log, in the hope of someone could
analyze and see how to improve, thanks;
