Hello Gents.
I have problem with b43 driver 5.100.138, it's not scanning networks for
unknown reason. I have broadcom wifi card PCIID is 14e4:4315, linux kern
ver. is 3.0. When i'm trying to launch iwlist scan, i'm getting "no scan
results".
for example:
sudo ifconfig wlan0 up
sudo iwlist wlan0 scan
No scan results.
With the older driver 5.10.56.2808, i see normal scan results. If you need
any more information, i will send.
The condition you report is known. Broadcom changed the TX/RX header structure
with firmware versions greater than 600, as shown by a 'dmesg | grep firmware'.
Those changes are not implemented in b43 until kernel 3.2.
These numbers are not b43 driver numbers, nor are they firmware numbers reported
by b43. They are the versions of Broadcom drivers.
If you look at
http://wireless.kernel.org/en/users/Drivers/b43#firmwareinstallation, you will
see that firmware should be extracted from Broadcom driver 5.100.138 "if you are
using kernel 3.2 or newer". For older kernels you should extract firmware from
the 5.10.56.27.3 of the Broadcom proprietary driver. Of course, 5.10.56.2808
will also work.
You could also get those changes by employing a bleeding-edge version of
compat-wireless. In that case, firmware from 5.100.138 would work.
