I just installed Fedora 25 on my laptop and the wifi icon is missing from the system menu and there is no wifi option in the Networks application. I researched a bit and found out that it is because my wireless adapter is a Broadcom adapter. After following the instructions given here in a previous answer as well as the instructions from this blog post, the situation is still the same. No wifi in the system menu or Networks application. Can anybody help me?

I am on a Lenovo G700 laptop, I am running Fedora 25, and lspci returns, among other things,

08:00.0 Network controller: Broadcom Limited BCM43142 802.11b/g/n (rev 01)
09:00.0 Ethernet controller: Qualcomm Atheros QCA8172 Fast Ethernet (rev 10)

Firstly, get an ethernet connection (like with an internet cable) or otherwise get an internet connection up and running via some other means (other than using your WiFi as obviously it's not working at the moment for you). Then run:

sudo dnf install -y https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-25.noarch.rpm https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-25.noarch.rpm
sudo dnf install -y broadcom-wl kernel-devel
sudo akmods --force --kernel `uname -r` --akmod wl
sudo modprobe -a wl

Now you should be able to go to the status menu (I'm assuming you're using the default workstation edition of Fedora with GNOME), if you're wondering what a status menu is see the diagram (with the red numbers in it) shown here, enter in your WiFi credentials and you should be able to connect to the WiFi without a drama.

The last modprobe command did the trick. Thanks a ton!

Due to the fact I didn't already have the kernel-devel package installed and it is not a required dependency I had to include the following two steps BEFORE running the modprobe command:

sudo dnf install -y kernel-devel
sudo akmods --force --kernel `uname -r` --akmod wl

Since you are using a PAE 32 bit kernel, you need to instal the kernel-PAE-devel package. The initial instructions are fine for Intel 64 bit machines but should note that Intel 32 bit machines require the kernel-PAE-devel package.

Firstly check kernel version using "uname -r " command then follow this step sudo dnf install kernel-devel-<kernel version="">
This solved my problem Please refer:http://unix.stackexchange.com/questions/341020/fedora-25-broadcom-wireless-bcm43228-no-wifi

@Surya_v9 Hi,

I updated kernel-headers and kernel-devel in fedora 25,

[root@localhost ~]# dnf install -y kernel-devel Fedora 25 - x8664 - Updates 483 kB/s | 23 MB 00:48
Last metadata expiration check: 0:00:37 ago on Mon May 29 11:46:16 2017. Package kernel-devel-4.10.17-200.fc25.x8664 is already installed, skipping. Dependencies resolved. Nothing to do. Complete!

but still cannot run 'akmods' !!!

please advise what i should do now. thanks.

For anyone who has problems with the current answer, you can try removing broadcom-wl first by:

sudo dnf remove -y broadcom-wl

then repeat the current approved answer above.

Good luck!

Sorry guys but it's all bullshit.

I've got same error on my Fedora-25-4.9.13-201.fc25.x8664 $ sudo akmods --force --kernel uname -r --akmod wl Could not find files needed to compile modules for 4.9.13-201.fc25.x8664 Are the development files for kernel 4.9.13-201.fc25.x86_64 or the appropriate kernel-devel package installed?

Problem solved by recomendations on http://linuxwireless.org/en/users/Dri...

You need make all form this topic:

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:

Toggle line numbers 1 export FIRMWAREINSTALL DIR="/lib/firmware" 2 wget http://www.lwfinger.com/b43-firmware/... 3 tar xjf broadcom-wl-5.100.138.tar.bz2 4 sudo b43-fwcutter -w "$FIRMWARE INSTALLDIR" broadcom-wl-5.100.138/linux/wl_apsta.o

Do exactly by listing above. And wifi appears when I comanded:

$ sudo modprobe b43

It's all. Peace!
