Hi all, wifi is working but no networks found on the list.
Broadcom BCM43142
Fedora 20
Dell Inspiron 14
How can you be sure that wifi is working?
What is the output from:
ifconfig
and:
iwconfig
ifconfig:

What’s the output from (run as root):
lshw -C network
in fedora you may need to install lshw:
yum -y install lshw*
lshw -C network

Add the RPMfusion (nonfree) repository:
http://rpmfusion.org/Configuration
then install akmod-wl (as root):
yum install akmod-wl
Then reboot.
I installed akmod-wl and got this:
[root@localhost denise]# yum install akmod-wl
Loaded plugins: langpacks, refresh-packagekit

Package akmod-wl-6.30.223.141-6.fc20.1.i686 already installed and latest version
Nothing to do
Rebooted and wifi network icon still still no network detected.
Please help…
What do you get from:
rfkill list all
Also, you could try to see if this makes it work:
sudo yum install broadcom-wl
(as per https://ask.fedoraproject.org/en/question/38364/broadcom-corporation-bcm43142-sony-vaio-fit-wifi/)
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
I have install broadcom-wl earlier on too.
When yum install broadcom-wl, this displayed:
Loaded plugins: langpacks, refresh-packagekit
Package broadcom-wl-6.30.223.248-1.fc20.noarch already installed and latest version
Nothing to do
Can you post up the result of:
sudo lsmod
I think this might be a blacklist job
Can you also post the output from:
lsusb
and
lscpi -vnn | grep -i net
sudo lsmod

Have you tried building the wl.ko module from here:
No, not yet. How is it be done?
Not 100% sure on Fedora … but try this
yum groupinstall 'Development Tools'
then
yum groupinstall 'Development Libraries'
then post the output from:
uname -a
[root@localhost ~]# uname -a
Linux localhost.localdomain 3.15.5-200.fc20.i686 #1 SMP Mon Jul 14 16:16:42 UTC 2014 i686 i686 i386 GNU/Linux
Anyone?
Sorry, I don’t know enough about Fedora to provide the required code for compiling a custom kernel :-[
