I have installed Ubuntu 16.04 on HP bs179tx laptop, but I am unable to connect to wireless networks. When I checked sudo lshw -C network, it is displaying *-network UNCLAIMED.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • What is your kernel version? uname -r – chili555 Feb 11 '18 at 14:04

With a temporary working internet connection by ethernet, tethered or whatever means possible, open a terminal and do:

sudo apt update
sudo apt install build-essential dkms git
uname -r

The last command will give you your kernel version; for example 4.13.0-32-generic. If your kernel version is 4.11 or higher, continue with the following:

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

If your kernel version is 4.10 or lower, then do:

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

In either case, reboot and your wireless should be working.

EDIT: The fact that your dkms status shows ‘built’ and not ‘installed’ suggests that there were problems, most likely errors, in the process I suggested. These errors cannot be ignored; they must be identified and fixed before the driver will build and install properly. Let’s start over. If, at any time, there are errors STOP and post them so we can fix it and proceed.

From the terminal:

sudo dkms remove rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414 --all
sudo rm -rf rtl8723de
git clone -b 4.10-down https://github.com/jeremyb31/rtl8723de.git
sudo dkms add ./rtl8723de

If there are errors here, STOP and report them.

sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

If there are errors here, STOP and report them.

If all goes without error, please check again:

sudo dkms status

We hope you see:

rtl8723de, 5.1.1.8_21285.20171026_COEX20170111-1414, 4.10.0-28-generic, x86_64: installed

If so, try:

sudo modprobe 8723de

Any improvement?
