Newer kernel not finding b43 firmware
 
I,m finding the newer kernel in the lfs book not finding the firmware?
I have an older lfs 7.6 I think running 3.16.1 kernel. Wireless device,
Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01) The wireles comes up.

Rebuilt lfs using the 3.19 kernel all booted ok, but no wireless I used the exact same kernel config file as before on the same machine, I also tried 3.19.3 4.0-rc6 and a 3.18.11 kernel no wireless.

dmesg

Code:

[    1.574106] b43-phy0 ERROR: Firmware file "b43-open/ucode5.fw" not found
I used the same b43 firmware dir put in /lib/firmware
I also rebuilt the firmware from here
http://linuxwireless.org/en/users/Drivers/b43/

I have tried the firmware from a debain install on same machine,
I have checked ucode5.fw is in /lib/firmware/b43 I also copied ucode5.fw into /lib/firmware.

I have also rebuilt 3.16.1 kernel into new lfs system wireless works.
Any ideas????

Anyone using b43 firmware or seen this problem

You probably should try the broadcom-sta driver if the firmware isn't working right.

Hi

I fixed the problem by setting "wireless configuration API" to a module and "Generic IEEE 802.11 Networking Stack" to a module in the kernel. Strange never had to do this before.
