Good day community.

I have finally updated everything related to my system from a 2 year old portage tree.
Everything went quite well, until I rebooted the system and saw that WiFi was not working anymore.

Whenever I try to bring up wlan0, this is what I get:
Code:
ifconfig wlan0 up
SIOCSIFFLAGS: No such file or directory

Here is the dmesg output:
Code:
dmesg -c
[13390.048185] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
[13390.048190] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found
[13390.048195] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.

My lspci output for that specific device (yeah it is a broadcom):
Code:
06:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
   Subsystem: Dell Wireless 1395 WLAN Mini-Card
   Kernel driver in use: b43-pci-bridge
   Kernel modules: wl

And the conf.d/net:
Code:
# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /usr/share/doc/openrc*/net.example* and save your configuration
# in /etc/conf.d/net (this file :]!).
config_wlan0=( "dhcp" )
modules="wpa_supplicant"
wpa_supplicant_eth0="-Dmadwifi"
wpa_supplicant_wlan0="-Dwext"

# The network scripts are now part of net-misc/netifrc
# In order to avoid sys-apps/openrc-0.12.4 from removing this file, this commen$
# added; you can safely remove this comment.  Please see
# /usr/share/doc/netifrc*/README* for more information.

The same happens when trying to start wlan0:
Code:
/etc/init.d/net.wlan0 start
 * Bringing up interface wlan0
 *   Starting wpa_supplicant on wlan0 ...
Successfully initialized wpa_supplicant
Could not set interface wlan0 flags (UP): No such file or directory
WEXT: Could not set interface 'wlan0' UP
wlan0: Failed to initialize driver interface
 *   start-stop-daemon: failed to start `/usr/sbin/wpa_supplicant'        [ !! ]
 * ERROR: net.wlan0 failed to start

I am well aware that the firmware files are not being loaded, which is the problem here.
Although, I recall doing this exact solution from here:
http://wireless.kernel.org/en/users/Drivers/b43#other_distros
To get it working the first time around.

Now I try to apply the same thing, download the tar, extract it and then move it to /lib/firmware.
I have the b43 folder there with the ucode15.fw file, but it STILL doesn't load it. Here's is an image of the file inside the path mentioned in the b43 website:
http://tinypic.com/r/2vl1ees/8

What can I do from there?
I already tried several other cases which do "almost" the same (wget, extract, move), but I still can't get it working with ifconfig up.

Is there some step I am missing to reload the firmware or make it know where it is exactly?

ShadowOne333,

Some wild guesses.
You have a new udev, whch no longer does any firmware loading but have not enabled fimware loading in the kernel.

The files
Code:
[13390.048185] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
[13390.048190] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found
need to be present in /lib/firmware

wlan0 has been renamed by udev ... but with missing fimware, it may just be missing entirely.

I did read something about it, that older udevs used to load firmware, but with newer ones that's not present anymore.
Exactly what version of udev changed that? Last one I had was udev-171 and that was working fine with b43.

Also, I think it is worth nothing that I don't have sys-fs/udev merged in the system, I have systemd.

I do have the files in /lib/firmware.
Actually, I included a link to an image that shows the exact path of the b43 folder with the ucode15.fw file in it.

Renamed?
How exactly?
If I do ifconfig or iwconfig, I still get wlan0 showing up:
Code:
ifconfig -a
wlan0: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether 00:24:2b:d6:8c:99  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Code:
iwconfig
lo        no wireless extensions.

sit0      no wireless extensions.

wlan0     IEEE 802.11bg  ESSID:off/any 
          Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm

ShadowOne333,

I can't support systemd, as I don't use it.

udev is a part of systemd, so you still have the udev code.
Your fimware install looks OK. Did you check your kernel?

Yep I did.

The kernel still has the same Device Drivers and modules installed I had before I updated my system.
Which is the Broadcomm 43XX driver (b43-pci-bridge is driver the kernel had in use before the update, and it still appears as that one).

I removed those same drivers from the kernel, make, make install, and then enabled them again and ran make, make install once more to be sure.
But no luck, that ucode15.fw is still showed as not found.

ShadowOne333,

Code:
$ grep FW_LOAD /usr/src/linux/.config
CONFIG_FW_LOADER=y


You need that in your kernel now.

@NeedySeagon:
I ran that exact command and got the same output as you do.

I copied the b43 folder to every damn firmware folder in the PC and I still can't get anything. XD
It still says that ucode15.fw is not found. o.O

Did you find a solution ?

I had the same problem.
Everything similar.

Firmware present, b43 enabled in kernel.
But unable to load it and to have a working wifi.
