I have just installed Kali Linux (64) on my laptop, but I haven't been able to get the Wi-Fi to work and unfortunately I don't have an Ethernet port on my laptop. It's worth mentioning that the Wi-Fi was working fine during the Kali installation.

These are what I'm getting when I run the following commands:

iwconfig:

lo        no wireless extensions
wlan0     IEEE 802.11abg  Mode:Monitor  Tx-Power=12 dBm   
      Retry short limit:7   RTS thr:off   Fragment thr:off
      Power Management:on

ifconfig:

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
    inet 127.0.0.1  netmask 255.0.0.0
    inet6 ::1  prefixlen 128  scopeid 0x10<host>
    loop  txqueuelen 1  (Local Loopback)

You need to install the linux-headers and the build-essential then build the driver from lwfinger git repo:

apt install build-essential git
apt update && apt upgrade && apt dist-upgrade

Reboot your system then run:

apt install linux-headers-$(uname -r)
git clone https://github.com/lwfinger/rtl8723au.git
cd rtl8723au
make
make install
modprobe -v 8723au

You should recive:

insmod /lib/modules/$(uname -r)/kernel/drivers/net/wireless/8723au.ko

The wireless module should be correctly loaded.

To make the module available evrey kernel update install dkms.

To get DKMS to work:

  • Install dkms
  • Copy this source to the directory /usr/src/8723au-0.1/
  • Run (as root):

# dkms add -m 8723au -v 0.1

  • Test a build:

# dkms build -m 8723au -v 0.1

From now on this drive should be available for any new kernels.

    Why would the install ISO have it but the distro lack it after the install? – user56041 Sep 26 '18 at 4:34

    @jww Because of the kernel update. – GAD3R Sep 26 '18 at 9:06

Try modprobe r8723au; this realtek card need firmware too. In Debian the package is named firmware-realtek
