[SOLVED] fedora-21 broadcom wifi

schneidz · 11-30-2014, 04:18 PM

hi. i am running fc21-beta4 on a live-usb and its not identifying my wifi adapter:

Code:

Did it install? Did you reboot or modprobe the driver?

schneidz · 11-30-2014, 04:43 PM

yes it installed and i did reboot:

Code:

[liveuser@localhost ~]$ sudo modprobe broadcom-wl
modprobe: FATAL: Module broadcom-wl not found.

EDDY1 · 11-30-2014, 04:45 PM

In the link I posted there are 2 drivers to be installed, were both installed

schneidz · 11-30-2014, 04:53 PM

i dont see what link you are mentioning. but i think the manual way is to do this:
http://www.broadcom.com/support/802.11/linux_sta.php but it seems like i need to update the kernel which i think is impossible in fedora-live (this is a company laptop). and i am unable to install kernel-devel for this running kernel:

Code:

[liveuser@localhost ~]$ uname -a -m -p
Linux localhost 3.17.1-302.fc21.x86_64 #1 SMP Fri Oct 17 20:05:46 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

schneidz · 11-30-2014, 05:09 PM

didn't work... seems like broadcom-wl/kmod-wl depend on the kernel being upgraded which i am not sure how to do live ?

EDDY1 · 11-30-2014, 05:16 PM

You can't update kernel

thanks, here is where i am at. trying to cmpile it manually but i am unable to install the current kernels devel source:

Code:

[liveuser@localhost Downloads]$ make
KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
make[1]: *** /lib/modules/3.17.1-302.fc21.x86_64/build: No such file or directory.  Stop.
Makefile:140: recipe for target 'all' failed
make: *** [all] Error 2
[liveuser@localhost Downloads]$ sudo yum install kernel-devel-`uname -r`
Loaded plugins: langpacks
No package kernel-devel-3.17.1-302.fc21.x86_64 available.
Error: Nothing to do

Check this 1 out

schneidz · 11-30-2014, 06:08 PM

^ good idea... i replaced the kernels but i ended up with

Code:

dracut: FATAL: Don't know how to handle 'root=live:UUID=302e89bc-5efb-.......
dracut: Refusing to continue
reboot: System halted

when i tried to reboot.

schneidz · 12-01-2014, 01:29 PM

i reverted back to fc-20 live-usb (thank goodness i created a dd backup before hand). these are the steps i did to get wifi working:

Code:

sudo yum install kernel-headers-`uname -r` kernel-devel-`uname -r` gcc
mkdir kmod-wl
cd kmod-wl
wget http://www.broadcom.com/docs/linux_sta/hybrid-v35_64-nodebug-pcoem-6_30_223_248.tar.gz
tar -xvzf hybrid-v35_64-nodebug-pcoem-6_30_223_248.tar.gz
make
sudo mkdir /lib/modules/`uname -r`/extra/net/wireless
sudo cp wl.ko /lib/modules/`uname -r`/extra/net/wireless
sudo depmod -a 
sudo rmmod bcma
sudo sh -c 'echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf'
sudo yum remove b43-openfwwf.noarch
sudo modprobe wl

EDDY1 · 12-01-2014, 01:41 PM

Great glad you got it working

schneidz · 12-12-2014, 11:51 PM

now that fedora-21 is out this is what i did:

Code:

sudo yum install kmod-wl
sudo depmod -a 
sudo rmmod b43 bcma
sudo sh -c 'echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf'
sudo yum remove b43-openfwwf.noarch
sudo modprobe wl

seems like a weird bug that the dev packages for the kernel were not available in the beta ?

This solution worked on a Lenovo N500 laptop. Thank you so much for posting. Saved me so much time.
