Hello, for quite sometime I'm trying to get linux working correctly with my laptop, I have problems with the wl driver from broadcom (installed from rpmfusion).
It's causing kernel panic (last lines mention [wl], without it it never occurs), I can't get b43 to work with my card, it just shows a network list, connects, works for 0.000005 sec, I try to load a page, the name will show up but not the contents, dmesg shows that authentication failed after 3 retries (it connected at first just fine).
Any ideas on how to get wifi to work? It's really essential to me, I want to use linux more and I can't, it's keeping me from it.
I was also thinking about trying that ndiswrapper, but I have no idea what files to copy where, how to start it and so on.

I've used ndiswrapper in the past, it work fine once you manage to find drivers that work with both - wifi card and your ndiswrapper version. I've read somewhere that b43 oss driver needs you to load firmware. Never had such card though so you need to search in the Internet. Any firmware package for your card? yum search firmware may show you what's available in your repos.

There's the firmware that I have already in my system, which doesn't work, only that...

Try these steps to correctly install the Broadcom 4312 Driver in Fedora:

sudo yum install b43-fwcutter

3. Extract driver

5. Activate the driver

sudo b43-fwcutter -w /lib/firmware/ wl_apsta_mimo.o

6. Reboot

If that doesn't work i'll give you the steps to use ndiswrapper.

Answer number 2: Try the official drivers:

There was no /driver directory in the tar, also I use Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) which apparently doesn't work with b43

I've updated to the correct version that provides a /driver.

( 2013-02-22 16:34:27 +0000 )edit

Well, no, it's pretty much the same one, just different version, still not compilled /src /lib only

It first that steps didn't work for me but then I went to answer number 2 and as part of the process I had to update my fedora https://ask.fedoraproject.org/question/9667/path-to-kernel-header/. Just after rebooting and updating kmod-wl everything worked perfectly!! nice post thanks

For the 4312, ideally, the STA driver from rpmfusion should work. If it doesn't, one can use the fwcutter method as outlined in the other answer.

I'm not sure of what chipsets the STA driver supports. If it worked for you, it seems like it supports 4312 too?

Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) yes surely working

STA doesn't work for me https://ask.fedoraproject.org/en/question/46860/how-to-setup-broadcom-4312-wireless/ and the instuctions here to install b43 are incomplete.

( 2014-05-26 04:58:54 +0000 )edit

sudo yum install b43-fwcutter


wget http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2

3. Extract driver

tar xjf broadcom-wl-4.178.10.4.tar.bz2


cd broadcom-wl-4.178.10.4/linux

5. Activate the driver

sudo b43-fwcutter -w /lib/firmware wl_apsta.o

6. Reboot

Steps 1 through 6 worked for me. Cannot thank you enough; I've spent about 3 hours on this issue, and was about to just give up.

I have Lenovo G550; Broadcom Corp BCM 4312 802.11b/g LP-PHY (rev-01). Until I tried what you recommended, I kept getting the following when I'd type: iwconfig enp7s0 no wireless extensions lo no wireless extensions.

Now, after I implemented 1 thru 6 above, I get: wlan0 IEEE 802.11bf ESSID "<wireless connection="">"</wireless>

Wish I understood the process better. I understand that something broadcom does makes it proprietary software and fedora can't reload. But, I don't understand what the "cutter" does.

Anyway. Thanks again!

Basically you extract and use the windows driver or the card.
