XPS 13 (9350) - Broadcom BCM4350 - Fedora 22 - Linux Kernel 4.4

I've had my XPS 13 (9350) for a couple of months now and have had issues with its Broadcom wifi chip. Been sharing my mobile phone's wifi via USB while waiting for kernel 4.4's support. Kernel 4.4 released a couple of weeks ago, but still, i haven't had my wifi work.

the following commands gave the following results:

# lspci -nn -d 14e4:

what i know is that the broadcom wireless chip is detected. the driver doesn't get loaded.

i tried a lot of solutions posted online, mostly for ubuntu and some for archlinux. didn't get anywhere. until now. here's what i did to make it work...

1. removed any bcm driver installed (rpm -qa | grep bcm should show nothing associated to broadcom)

2. removed broadcom-wl and reinstalled broadcom-wl

3. ran # sudo modprobe wl

4. ran # sudo modprobe brcmfmac

whew! now, i can use my mobile phone away from my xps ;D

ps. to make sure your wifi works on boot, make sure brcmfmac is not in /usr/lib/modprobe.d/broadcom-wl-blacklist.conf
