    ubuntu 20.04 WIFI not showing

    After installing Ubuntu 20.04 for a week, the WIFI icon has disappeared. Using this command:
    Code:
    lspci | grep Wireless
    returns
    02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

    I have updated the software using:
    Code:
    sudo apt update
    Code:
    sudo apt upgrade
    and restart but the WIFI icon is still missing. My home WIFI works fine.

    Any idea on how to solve the internet connection?

    If LAN works, run
    Code:
    sudo apt install build-essential dkms rtl8821ce-dkms
    Reboot and turn off SecureBoot

    Re: ubuntu 20.04 WIFI not showing

    I get this message
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    dkms is already the newest version (2.8.1-5ubuntu1).
    build-essential is already the newest version (12.8ubuntu1.1).
    rtl8821ce-dkms is already the newest version (5.5.2.1-0ubuntu4~20.04.2).
    The following package was automatically installed and is no longer required:
    libfprint-2-tod1
    Use 'sudo apt autoremove' to remove it.
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    Then I disabled SecureBoot via BIOS setting. No WIFI still. Help please?

    Note that running the command:
    Code:
    sudo lshw -C network
    returns

    and then reinstall it:
