what happens if you run:

modprobe wl

does wireless spring to life ?

if not, what (if anything) was returned in the terminal ?

and what is the output from:

lshw -C network

again ?

23

Fatal ERROR.

OK, what is returned if you run:

su

then

yum install akmod-wl
25

Nothing to do, already installed .

26

OK, let’s try a different method…
run:

su

then

yum install broadcom-wl

then if necessary reboot.

If wireless doesn’t spring to life, what’s te output from:

modprobe wl

now ?

27

ALready installed and the same Error ( FATAL).

i think i shouldn’t updated my os !

28

OK, try removing both:

su

then

yum remove akmod-wl

then

yum remove broadcom-wl

then

yum update -y

then REBOOT

then run:

su

then

yum install akmod-wl "kernel-devel-uname-r == $(uname -r)"

then

yum update -y

then REBOOT again.

Any difference ?

29

Mark, the problem persit ! ( Fedora suggesting me to update another time ! proposing kmod)

30

Give it a shot then :wink:

Do a full system update, reboot, then try installing kmod-wl

31

It worked ! Finally , Think you mark !

32

33

Today I install fedora 20 and wifi is not working while LAN is working properly.

Also I have tried below options but problem is same yet.

34

OK, running:

su

then

yum remove akmod-wl

then

yum remove broadcom-wl

then

yum update -y

then REBOOT

then run:

su

then

yum install "kernel-devel-uname-r == $(uname -r)" kmod-wl

then

yum update -y

then REBOOT again.
