    Let's start by identifying your exact device. Insert the device and run this terminal command: `lsusb`. Next, edit your question to add the result. Welcome to Ask Ubuntu. – chili555 Jul 04 '21 at 01:38

First check your USB configuration by typing lsusb in your terminal and check it.. see the image for more info..

If your USB configuration is this 0bda:f179 Then you can try this following commands...

install :

sudo apt-get install build-essential git dkms linux-headers-$(uname -r)    
git clone https://github.com/kelebek333/rtl8188fu    
sudo dkms add ./rtl8188fu    
sudo dkms build rtl8188fu/1.0    
sudo dkms install rtl8188fu/1.0    
sudo cp ./rtl8188fu/firmware/rtl8188fufw.bin /lib/firmware/rtlwifi/

Run following commands for disable power management and plugging/replugging issues:

sudo mkdir -p /etc/modprobe.d/    
sudo touch /etc/modprobe.d/rtl8188fu.conf
echo "options rtl8188fu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/rtl8188fu.conf

How to uninstall :

sudo dkms remove rtl8188fu/1.0 --all    
sudo rm -f /lib/firmware/rtlwifi/rtl8188fufw.bin   
sudo rm -f /etc/modprobe.d/rtl8188fu.conf

  • Please be aware that installing the wrong driver can rise future compatibility issues with OP devices. Providing a more general answer would be preferred, as well as waiting for OP to provide more information about their hardware. – Alexandre Teles Jul 12 '21 at 03:32

Just a shorter version from the GitHub link given in the detailed answer by @Vashishth Patel that worked for me is:

sudo add-apt-repository ppa:kelebek333/kablosuz
sudo apt update
sudo apt install rtl8188fu-dkms
