    thanks for your respons and welcoming. I get this respons after doing " sudo apt install inxi ".

    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    E: Unable to locate package inxi

    I suspect this is bc i wiped my SSD when I installed Ubuntu (I used that option). Hence I can't do the second command.

    The package probably needs the internet to install.

    Try the following and it should list the internet controller info near the bottom of the output.
    Code:
    lspci

    Code:
    sudo apt-get install git build-essential dkms linux-headers-$(uname -r)
    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 /usr/src/rtlwifi-new-0.6/firmware/rtlwifi/* /lib/firmware/rtlwifi/
    Reboot and deactivate SecureBoot. If the signal is weak, try
    Code:
    echo "options rtl8723de ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723de.conf
    and reboot again. If its not working then repeat the last line with "ant_sel=1" instead

    thanks for your answer. I have tried everything you have said (secure boot is disabled as well) and and it still says 'no WiFi adapter found' in the settings.
    Are there other ways I can try?
