[SOLVED] Wireless firmware missing

[OneHarsh]

i have b43 broadcom driver. I installed all the firmware driver, but it still says firmware missing for wireless networks.
Some of the useful informations are
lspci -vnn | grep 43 -A7

PS: please give any solution that help me offline installation, bcoz i cant use internet without my wifi.

Not all versions of the BCM4312 chipset work with the b43 driver. IMO, you will have a better chance of success with the Broadcom 802.11 STA Linux driver (aka broadcom-wl). A binary yum-installable version of it is available from RPM Fusion.

But if you want to press on with b43 just to find out, then confirm that the firmware is there. This should list a few dozen .fw files...

ls /lib/firmware/b43

What files did you use when you extracted the firmware? Make sure you installed version 4 firmware. I'm still extracting the firmware from wl_apsta_mimo.o that I get from broadcom-wl-4.150.10.5.tar.bz2 at OpenWrt. It's not the latest tarball, but I intend to keep using it until it stops working.

Next, look at the loaded kernel modules to confirm b43 and ssb are there and there are no conflicting modules (unlikely, but look anyway)...

lsmod | sort

Then restart NetworkManager and look in the panel applet for available networks...

su
service NetworkManager restart

If there are no networks available when some are known to be in range, then I think I would move on to broadcom-wl.

thanks.. that helped

I have got the same problem.. and when doing

lspci -vnn | grep 43 -A7

i got the same out put as of OneHarsh ....
while doing
ls /lib/firmware
I didnt got b43 but I got b43-open

then I did lsmod | sort

and also
su service NetworkManager restart

but again the problem is same.... that is device not ready (firmware missing) any solution please.....

The b43-openfwwf firmware that is in the Fedora repos supports only about four Broadcom chipsets, and the BCM4312 is not one of them. If you have confirmed that you have a BCM4312 chipset like OneHarsh, then you should install the so-called version 4 firmware for it. Another idea is to forget about b43 altogether and install the so-called broadcom-wl driver from RPM Fusion. Both of those ideas are explained in the Broadcom wireless HOWTO...

download, patch it, compile, install.(tested on fc15)

better than b43 or whatever ****.
