Unable to connect with wifi on Fedora 23

edit

You need to install rpmfusion.org free and nonfree then you need to install akmod-wl and kernel-devel

Broadcom Wireless Install Guide

# uname -a

Linux Fedora 4.4.6-300.fc23 #1 SMP Wed Mar 16 22:10:37 UTC 2016 GNU/Linux

# dnf install kernel kernel-devel kernel-headers -y

#dnf install gcc gcc-c++ -y

#lspci |grep BCM

#lsmod  | grep "brcmsmac\|b43\|ssb\|bcma\|wl"

If any of these are installed, remove them:

# rmmod b43
# rmmod brcmsmac
# rmmod ssb
# rmmod bcma
# rmmod wl

To blacklist these drivers and prevent them from loading in the future:

# echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist brcmsmac" >> /etc/modprobe.d/blacklist.conf

I recently did a fresh install of Fedora 23 on my Lenovo S20-30 and ran into a similar issue.

When I got the laptop Fedora 22 was out and to get Fedora to use the pesky Broadcom chip I did the following install:

sudo dnf akmod-wl kmod-wl broadcom-wl

That installed all I needed to get wifi up and running.

So I did the same when doing the fresh install of Fedora 23.

Yet the only kernel that worked was the one that is shipped with Fedora 23, the updated one 4.4.6 did not. I tried to reinstall and run sudo modprobe wl to no avail.

Thanks to aeperezt suggestion it now works!

This is what I did:

sudo dnf akmod-wl kmod-wl broadcom-wl kernel-devel

Then reboot.

PS: Sorry if this was a long-winded reply, but I felt it was important to show what I did before it worked for me.
