B43 requiring bcma AND ssb???
I'm fairly new to Linux and there is only one thing that still forces me to reboot and start windows instead every now and then.
When I'm at home I want to connect my mobile devices (tablet, smartphone) to wifi, but since our hotspot's antenna cannot supply my room with our WLAN I used to start a "Virtual Router" on my laptop, thus sharing it's ethernet connection with my devices via its wlan-card in host mode.
Under Linux, I found out, this is only possible with hostAPD and the only driver supporting host-mode on my wlan-card (bcm43225) is b43. But unfortunately, Fedora's standard driver was brcmsmac. Therefore I am messing around with the installation of b43 for some time now but it still refuses to work.
At least I got it to auto-load on boot by creating an entry in etc/rc.local, but I think it isn't a good sign already that the kernel doesn't load b43 itself.
But as of now, I am more concerened with the question giving its name to this post. When I run lsmod | grep b43 I get the following:
b43 365923 0 bcma 30183 1 b43 ssb 61441 1 b43 mmc_core 102497 2 ssb,b43 mac80211 492420 1 b43 cfg80211 195764 2 mac80211,b43
Error: could not insert module b43.ko: Unknown symbol in module
In dmesg I also found the following line concerning b43:
[ 10.426461] Broadcom 43xx driver loaded [ Features: PMNLS ]
I am running Fedora 17beta (kernel 3.3) and I wouldn't be surprised if you told me that it's simply because of a bug in fc17, but at least I am sure then.
Huge thanks in advance, looking forward to any answers from you

You might want to give this a try.
$ su - password: # gedit /etc/modprobe.d/blacklist.conf
blacklist b43 blacklist ssb
# init 6

Hello! First of all thank you for the response.
I already blacklisted ssb and bcma before (except b43, but that seems strange, since I want it to load). Essentially my problem is that I want to use b43, but it is not loaded by the kernel by default. And when I force it to load on startup using rc.modules, both ssb and bcma are loaded as dependent modules by modprobe, but I was afraid that both might interfere with each other. Maybe I am wrong, but that is the first thing I could get hold of as a possible reason for b43 not to work.
Only to clarify, what I DID:
I blacklisted brcmsmac, because I wanted to replace it by b43
Then I have installed b43-fwcutter and I have executed all command from linuxwireless.org/en/users/Drivers/b43#other_distros
If you are using the b43 driver from 3.2 kernel or newer: After installing b43-fwcutter, download version 5.100.138 of Broadcom's proprietary driver and extract the firmware from it: 1 export FIRMWARE_INSTALL_DIR="/lib/firmware" 2 wget [protocol not allowed]lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 3 tar xjf broadcom-wl-5.100.138.tar.bz2 4 sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.oCode:
I DID NOT
Alias the correct module to my wlan0 device as said at fedoramobile.org/fc-wireless/bcm43xx-yum-extras because it seems obsolete (modprobe.conf doesn't exist any more)
Thank you for helping me out, I really WANT this to work, otherwise I will be forced to switch to windoze again and again.

I'm not that much well versed on wireless too but maybe it could help if you can post all the outputs of the command as directed here.
Maybe the wireless gurus in LF can spot what you need for your concern. Good luck man!nujinini

Thanks nujinini for the REALLY quick answer
Ok, all outputs from the beginning:

Hey again, I finally found the solution for my problem:
I configured and compiled a kernel and stumbled over the option to tell b43 to ignore cards which are supported by brcmsmac.
This option had been enabled of course in the standard Fedora17 kernel (and it is probably in the most other kernels, too). I simply disabled it and now everything works perfectly.
Nevertheless, thank you all for at least viewing this thread with the intention to help
