I recommend checling to see which kernel is installed. At the following Realtek Semiconductor web document the are Linux drivers by kernel number for the RT8111 NIC.

 

A Realtek RT8111 device is a LAN device, not wireless.

 

Be aware that as far as I understand, there is an Intel wireless adapter installed in the desktop. That is llikely to be why there are no drivers available. 

 

In the Windows 10 installation, check to see what is installed as a ethernet LAN device and wireless adapter by looking in the Device Manager.

A driver for the adapter is available in the GIT sources

See the following forum thread from 2017 which shows how to download and install with the appropriate terminal commands.

A big thanks to you erico, i was able to resolve the issue

i am providing all the steps consolidated which may help any other user to get things done with just 3 simple steps.

Step1: Verify if your linux kernel is above 4.17 to check that simply type
uname -r
if it is not above 4.17 u should follow step 2 else u can jump to step 3

Step2: Download required files and install to upgrade your kernel to 4.18.14
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18.14/linux-headers-4.18.14-041814_4.18.14-041814.2...
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18.14/linux-headers-4.18.14-041814-generic_4.18.14-...
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18.14/linux-modules-4.18.14-041814-generic_4.18.14-...
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18.14/linux-image-unsigned-4.18.14-041814-generic_4...
sudo dpkg -i *.deb
now reboot your system and verify with step 1 to check if the kernel has been upgraded

Step3: Install the driver
sudo apt-get install dkms git build-essential

git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
sudo cp -r rtlwifi_new/firmware/rtlwifi/ /lib/firmware/rtlwifi
echo "options rtl8723de ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723de.conf

There may be some representational error but this would be the actual CMD

git clone -b extended https://github.com/lwfinger/rtlwifi_new.git

You have not stated which flavor of Linux you are running and that would help.

Open the terminal as a root user or use the sudo command as normal user and input the admin password when requested.

 

Once you have the terminal as a root user there should be no problem running the command.
