How it works

Broadcom BCM4350 (Dell XPS 13 9350) network card misbehaves at system shutdown (firewalld time out) and on power saver feature (random crash), this script apply a workaround to makes usable the WiFi network card.

How to Use

Blacklist Kernel Driver

Blacklist the brcmfmac kernel module at system startup. This disable WiFi Broadcom kernel module at boot.

Option A - Change Grub config with grubby.

Execute from console:

sudo grubby --update-kernel=ALL --args="modprobe.blacklist=brcmfmac"

Option B - Or manually change Grub Config

Add modprobe.blacklist=brcmfmac in GRUB config.

Edit the file /etc/default/grub and add modprobe.blacklist=brcmfmac to the end of GRUB_CMDLINE_LINUX

Example:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="resume=UUID=XXXXXXXXX rhgb quiet modprobe.blacklist=brcmfmac"
GRUB_DISABLE_RECOVERY="true"
