That is correct: * with pio=1 it works * without pio=0 you get the above message, but then it is never able to connect. > That being said, it is supposed to work on linux >= 3.0, so I'd try with > a more recent firmware just to see if it helps. > (cf. > http://linuxwireless.org/en/users/Drivers/b43?highlight=%28b43%29#List_of_firmware > ) Ah, I didn't even think to upgrade the firmware.. the debian package that installs the firmware grabs this url: http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2 which appears to be a few versions behind. I'm installed broadcom-wl-5.10.56.27.3_mipsel.tar.bz2 and am testing kernels now. 3.1.0-1-686-pae with the new firmware seems to be working :-) It went from 2011-11-22 12:24:23 check=DL ok=True download_time=26.44 timeout=False min_speed=544 avg_speed=774 max_speed=888 to 2011-11-22 12:42:16 check=DL ok=True download_time=11.75 timeout=False min_speed=1376 avg_speed=1743 max_speed=1976 and CPU usage is only 15% now. > (it's not debugging the right part, and I won't be of much use since > I've never had a b43-compatible device, but you can have more > information about the deauth if you run "iw event" to get a few more > messages, or maybe wpa_supplicant debug output, since it says "local > choice" I would suppose wpa_supplicant isn't happy with something.) If I had to guess I think it is just hosed and timing out somehow... not important now :-) -- -- Justin Azoff -- Network Security & Performance Analyst _______________________________________________ b43-dev mailing list b43-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/b43-dev
