  • It is not a related hardware config. Please edit your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. Please post it as text, not as a screenshot.

My WIFI issue is resolved. i have installed RTL8188GU driver and reboot the system.

Please follow the below steps:

sudo apt-get install build-essential git dkms
git clone https://github.com/McMCCRU/rtl8188gu.git
cd rtl8188gu
make
sudo make install
sudo reboot

After rebooting the system check WIFI should work.

  • This is great that you found the solution! But if there is a dkms install way, it is better to use that method because installing with make will break after a kernel upgrade. The dkms in the first line suggest that the author has a dkms method too.

  • @Pilot6 so i have to install dkms?

  • You already installed dkms, but the installation procedure didn't use it.

  • I looked into that git readme and it doesn't have dkms.conf. So you'll need to re-install the driver starting with cd rtl8188gu after each kernel upgrade, unless you create a dkms. And you don't need sudo apt install --reinstall linux-firmware.

  • Okay, so did you know how to use it. because i don't want to face any problem when kernel is upgrade

I tried running

"sudo apt-get install build-essential git dkms"

but it is showing me error as:

Package 'build-essential' has no installation candidate.
