I installed broadcom-sta-common and it caused WiFi to not work , i purged it but i still need to run sudo modprobe brcmsmac manually after boot to make WiFi work.

How can i make it work automatically like before ?

some outputs :

rahman@debian:~$ sudo rfkill list 
0: hp-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

rahman@debian:~$ uname -a
Linux debian 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u3 (2017-08-06) x86_64 GNU/Linux

rahman@debian:~$ lspci -nn -d 14e4:

rahman@debian:~$ cat /etc/modprobe.d/blacklist.conf 
blacklist brcmsmac

Update : While using wl module

it works on startup now after adding brcmsmac to /etc/modules

You should use the wl instead of brcmsmac as recommended on the official website.

Also you should unload the conflicting driver witch cause the wifi stop until you reboot your OS.

Following the steps described on the debian wiki :

Add non-free component to your /etc/apt/sources.list:

deb http://httpredir.debian.org/debian/ stretch main contrib non-free

Install the required package:

apt-get update
apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

Unload conflicting drivers:

modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

Load the wl module:

modprobe wl

wireless.wiki.kernel.org

brcmsmac

Name    PCI Device ID
BCM4313 0x4727

Please note: at least BCM4313 is not fully supported. Some models appears to work (users reported success), but some don't, and there's no indication that this is going to change. For example: http://marc.info/?t=138817851800006&r=1&w=2

  • I've found that wl does work on startup and fixes keyboard WiFi back-light but it doesn't work when changing MAC and doesn't support monitor mode , so i'm back to use brcmsmac and still trying to make it work on startup – A.Rahman Mahmoud Sep 9 '17 at 13:01
  • @A.RahmanMahmoud Please edit your question , add the output of iw list | grep "Supported interface modes" -A12 , clarify what you need to get working – GAD3R Sep 9 '17 at 13:59
  • i Updated it with both modules outputs – A.Rahman Mahmoud Sep 9 '17 at 14:39
