So I have Kali Linux installed on my Lenovo g500 laptop. Wired connections work just fine but I cannot connect to wireless access points or detect them. I am literally out of ideas, so here is the information that might help you help me : -When I start up the computer(Kali Linux is my only OS and its not from a live CD or anything like that) wireless isn't even turned on, and it doesn't even detect the card. Here is the output of iwconfig and ifconfig after booting:

# iwconfig

lo        no wireless extensions.

eth0      no wireless extensions.

# ifconfig

eth0      Link encap:Ethernet  HWaddr 20:1a:06:99:1e:2c  
          inet addr:***.***.*.***  Bcast:***.***.*.*** Mask:255.255.255.0

I have been solving this by doing this:

Now I see a lot of 'Fatal's in there and I don't know if that's ok or not. Now the output of ifconfig and iwconfig is:

# iwconfig

Now on the right corner when I click on the network icon it shows :

 Wired Network
  Wired Connection 1
   disconnect ##this is a clickable button ... 
 Wireless Network (wlan0)
   disconnected ##unclickable button
 Wireless Network (wlan1)
   disconnected ##unclickable button

I have a wireless router that has worked on this laptop before from Windows 7 and from Linux Mint.

there's a large number of posts about the Broadcom BCM43142 having issues in kali, although i did dig up this bit:

add all Kali repositories to /etc/apt/sources.list:

deb http://http.kali.org/ /kali main contrib non-free
deb http://http.kali.org/ /wheezy main contrib non-free
deb http://http.kali.org/kali kali-dev main contrib non-free
deb http://http.kali.org/kali kali-dev main/debian-installer
deb-src http://http.kali.org/kali kali-dev main contrib non-free
deb http://http.kali.org/kali kali main contrib non-free
deb http://http.kali.org/kali kali main/debian-installer
deb-src http://http.kali.org/kali kali main contrib non-free
deb http://security.kali.org/kali-security kali/updates main contrib non-free
deb-src http://security.kali.org/kali-security kali/updates main contrib non-free

install "broadcom-sta-dkms" package (ver 6.30.223.248-1)

the above is taken from here. as an alternative, you can also add a usb wifi dongle - there's a pretty good list here. good luck!

  • I did what you told me, but i its the same thing, broadcom-sta-dkms package installed just fine, i restarted the laptop and nothing changed. Is it possible kali linux doesent support my wireless card at all?(and also thank you for responding, it means a lot to me :D ) – XenoWad Aug 11 '15 at 21:05
  • that is totally possible... sorry. it might be worth investing in one of the usb wifi sticks. personally, i have 2 of the TP-LINK TL-WN722N and they're not bad. i'm sure there's better, but kali supports them with no additional fuss and they're less than 15$ on amazon, so it's not like you're breaking the bank for a fix. cheers! – will_ Aug 12 '15 at 1:16
  • Well thank you very much for the help, i will research a little on what wifi stick i should get . Nice day to you sir :) ! – XenoWad Aug 14 '15 at 22:07
