Unable to detect wifi network in Ubuntu 18.04.1 LTS

Question

I tried following the steps mentioned in this link: make: *** [modules] Error 2

When I am typing this command:

sudo modprobe rtl8723de

I am getting the error:

modprobe: FATAL: Module rtl8723de not found in directory /lib/modules/4.15.0-34-generic

Previously I tried the command rm /etc/modprobe.d/iwlwifi.conf as it was giving bad option error.

Steps as follows:

$ sudo rm -r rtl8723de*
rm: cannot remove 'rtl8723de*': No such file or directory

$ sudo apt update && sudo apt -y install git
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

$ git clone https://github.com/lwfinger/rtlwifi_new.git
done

$ cd rtlwifi_new
$ make
make[1]: Leaving directory '/usr/src/linux-headers-4.15.0-34-generic'

$ sudo make install
make -C /lib/modules/4.15.0-34-generic/build M=/home/shubham/rtlwifi_new modules

Did each and every step leading up to 'modprobe' complete without error? — chili555, Sep 29 '18 at 20:58
Did you clone a new fresh copy just now? Please see my edit at the question you linked and follow that procedure. The reason that I think you are working on an old copy of the git is that your process builds 15 modules. I just ran make clean, git pull and make and I get 19 modules. Presumably, rtl8723de is one of the missing modules. — chili555, Sep 29 '18 at 21:27
Please run the entire process at my edit and show us the complete output here: http://paste.ubuntu.com Give us the link. — chili555, Sep 29 '18 at 21:43

Please try:

sudo rm -rf rtlwifi_new
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install 
sudo modprobe rtl8723de

Post any errors, please.

We cloned the 'extended' branch of the git. Mr. Finger currently maintains nine branches for this driver suite. He adds and deletes branches from time to time. Therefore, not every answer posted on every forum will be valid forever.
