I am trying to install wifi modules for BCM43142 in fedora22.

I installed following modules: kmod-wl-, akmod-wl-, broadcom-wl-

I rebooted the system after installing the modules. But wifi is still not working.

I am new to fedora. Could you help me how to proceed further.

Thanks in advance :)

Do you have UEFI, on that machine?

I can see UEFI boot option in addition to legacy boot in boot screen. Not sure if that implies existence of UEFI??

Try to turn off UEFI secure, look at this:

I purchashed a DELL XPS 13 notebook and installed Ubuntu 15.04 on it (Bios is A04). I was experiencing several random crashes. I believe this is the bug:

I then decided to switch to Fedora 22 Workstation. In order to get wifi to work one has to proceed as follows: Use a cable connection. Disable secure boot in Bios. Install the RPM Fusion repository (free and, most importantly, nonfree):


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

and reboot. Wifi should work.

I recommend instaling akmod-wl. That way, the module will be rebuilt at boot-up when the kernel is upgraded.

To get bluetooth to work, follow the instructions available here:

I added two parameters to GRUB_CMDLINE_LINUX in /etc/default/grub , namely:

acpi_osi=!Windows\ 2013 psmouse.resetafter=0

Then, as root,

grub2-mkconfig -o /boot/grub2/grub.cfg

That solves some minor trackpad glitches.

To those who are coming from Ubuntu, I recommend installing Fedy

and PostInstallerF

Installing codecs et al. becomes very easy when one uses these two tools.
