“Wifi adapter not found” is one of the common problems faced by ubuntu users. Even though it is common there are ways to fix this issue. Here are some possible ways to fix it:
FOR UBUNTU 18..04
•First, try to connect with the wired Internet connection (or you can use Mobile Tethering) and use the following commands to install missing Wi-Fi drivers.
•Clone the repository (use your Terminal):
git clone https://github.com/lwfinger/rtlwifi_new.git
•Enter the cloned folder:
cd rtlwifi_new
•Check out the extended branch:
git checkout extended
•Start installation:
sudo make install sudo modprobe -r rtl8723de sudo modprobe rtl8723de
That’s it! You have now successfully installed the RTL8723de Wi-Fi driver on your Ubuntu 18.04 system. This repo also contains the driver for RTL8723be and much more RealTek devices.
•If that doesn’t work just go and do this:
sudo apt purge bcmwl-kernel-source sudo sed -i ‘/blacklist bcma/ d’ /etc/modprobe.d/blacklist.conf sudo sed -i ‘/blacklist brcmsmac/ d’ /etc/modprobe.d/blacklist.conf
•Reboot. If wifi does not come on, do:
sudo modprobe -v brcmsmac sudo modprobe -v bcma
FOR UBUNTU 19.10
Start by installing all packages required for the installation of the driver
sudo apt install bc module-assistant build-essential dkms
Then: git clone https://github.com/tomaspinho/rtl8821ce.git
Move to the directory: cd rtl8821ce
And install the driver: sudo ./dkms-install.sh
Hope it worked for you
