Hi all, I installed a fresh Fedora 20 on my 64-bit Dell Inspiron laptop. I got the wireless working fine: once. After a reboot, F20 is no longer seeing a wireless capability.

The wireless worked fine on this machine in Fedora 17 and 19, and it works under Win7.

I followed instructions on this site's question #9998. The present status of the problem is --

The rpmfusion repo is enabled.

Output from command 'lspci' included:

0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

Output from command 'yum search broadcom' included:

b43-fwcutter.x86_64 : Firmware extraction tool for Broadcom wireless driver
b43-openfwwf.noarch : Open firmware for some Broadcom 43xx series WLAN chips
bcm43xx-fwcutter.x86_64 : Firmware extraction tool for Broadcom wireless driver
broadcom-wl.noarch : Common files for Broadcom 802.11 STA driver
b43-tools.x86_64 : Tools for the Broadcom 43xx series WLAN chip
crystalhd-firmware.noarch : Firmware for the Broadcom Crystal HD video decoder
libcrystalhd.i686 : Broadcom Crystal HD device interface library
libcrystalhd.x86_64 : Broadcom Crystal HD device interface library

'yum install broadcom-wl' returned

Package broadcom-wl- already installed and most recent version

Command 'modprobe broadcom-wl' returned:

modprobe: FATAL: Module broadcom-wl not found.

Trying 'modprobe broadcom-wl-' returned something similar (I tried several variations).

So now I'm stuck. Yum sees the Broadcom package, but modprobe doesn't.

Rebooting doesn't help, nor does pressing the physical key that turns the wireless on and off.

Thanks in advance for any help or advice.

P.S.: I just realized I haven't tried deleting the wireless package and reinstalling it. I'll try that (perhaps I'll wait until the morning) and update this thread whether it succeeds or fails.

Deleting and reinstalling the wireless package made Fedora 20 see that it has wireless capabilities, but no networks are showing to connect to. So I'm still stuck.

Hi: Have you tried enabling [] (frre/non-free) and installing the kmod-wl package?
Kind regards

@casep: Thank you very much for your reply. I'm ashamed to admit I got so caught up in my struggles with F20 that I neglected to update this thread. My wireless is working (for now); pressing the physical wireless on/off key while the 'show available networks' dialog box was open seems to have done the trick. If the wireless dies again, I'll try installing the kmod-wl package and see if I have any better luck.

@casep, I had the same issue. Didn't realize that the wifi button worked on my Alienware with Fedora 20, after 4 hours and comign across this thread I was able to resolve it.

@jazcao53 thank you, your solution worked for me. Enabling and disabling the wifi did it. cheers

Same problem here, I ran a 'yum update' which updated 'broadcom-wl' and 'kmod-wl' and solved the problem.

RPMFusion lags behind kernel updates by a few hours. It's a good idea to either also install the akmod packages or not use the newer kernel until you've seen the corresponding kmod updated. This applies for wifi, nvidia and all other kmod packages.
