I installed Fedora 23 on my Dell XPS 13 (9350). This model comes with a Broadcom BCM4350 wifi chip, which does not work out of the box. As suggested in many postings, I manually updated the kernel to a version that includes the correspoding driver. I am actually running Kernel Secure Boot is disabled. However, wifi is not working, there is no wifi interface in the Gnome network tool nor in the output of ip link.

lspci -k shows:

3a:00.0 Network controller: Broadcom Corporation Device 43a3 (rev 08) Subsystem: Dell Device 0021 Kernel modules: brcmfmac

suggesting there is no driver in use as there is no line like

Kernel driver in use: brcmfmac

What can I do at this point to activate the driver? Please consider that my linux/fedora knowledge is very limited :) Thanks!

PS: Which tag do you use for terminal output looking nice?

While the driver brcmfmac is in the kernel it needs a corresponding firmware file brcmfmac4350-pcie.bin in /usr/lib/firmware/brcm/.

Do you have linux-firmware package installed?

dnf install linux-firmware
