I followed this stack post its not working for Linux mint.

Tried to install rtl8723de driver but returns error

$sudo apt-get install build-essential git dkms
...
$git clone -b 4.10-down https://github.com/jeremyb31/rtl8723de.git
$sudo dkms add ./rtl8723de
$sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

  • Your title is wrong and you cloned the wrong repo. Your ethernet card is the rtl8111/8168/8411 and your wifi is the RTL8723DE [10ec:d723]. Please read the instructions of your linked driver and try again. There are two instructions "if your kernel is lower than 4.11" and "If you have kernel 4.11 and newer" and you have tried the first one, but your kernel version is 4.15. You need to clone the repo with `git clone https://github.com/jeremyb31/rtl8723de.git`. – Freddy Oct 26 '19 at 01:20
  • Thanks for the reply but it shows, ERROR (dkms apport): binary package for rtl8723de: 5.1.1.8_21285.20171026_COEX20170111-1414 not found Error! Bad return status for module build on kernel: 5.0.0-32-generic (x86_64) Consult /var/lib/dkms/rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414/build/make.log for more information. – VA splash Oct 26 '19 at 05:03
  • Thanks bro for correcting me.Googled and it worked https://askubuntu.com/questions/961299/cannot-see-my-wifi-10ecd723-when-trying-ubuntu – VA splash Oct 26 '19 at 05:16
  • The above link worked for Ubuntu but this one worked for linux mint https://subinsb.com/install-realtek-d723-wifi-driver-linux/ – VA splash Oct 26 '19 at 18:44
