I have installed Ubuntu 16.04 recently alongside Windows 10.

Here is an image of the terminal after executing the instruction lspci -nnk | grep -A3 -Fe '[0280]'; rfkill list

Terminal image

The kernel version is 4.13.0-32-generic

  • Could you please [edit] your question to include the output of the terminal command lspci -nnk | grep -A3 -Fe '[0280]'; rfkill list? Thanks. – David Foerster Feb 10 '18 at 08:09
  • What is your kernel version? Please edit your question to add the result of the terminal command: uname -r – chili555 Feb 10 '18 at 14:44
  • With respect to the possible duplicate, Dinesh needs the branch for kernel versions 4.11 and higher. – chili555 Feb 11 '18 at 13:50

With a temporary working internet connection, open a terminal and do:

sudo apt update
sudo apt install build-essential dkms git
git clone -b 4.11-up https://github.com/jeremyb31/rtl8723de.git
sudo dkms add ./rtl8723de
sudo dkms build rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
sudo modprobe rtl8723de

Reboot and your wireless should be working.
