This tutorial is a rewritten of the previous ‘Fix ‘No WiFi Adapter Found’ for HP Laptops with Ubuntu 18.04‘, since wireless will stop working after installed or upgraded to a new Linux Kernel.

Following steps will install the newest Realtek rtlwifi codes including rtl8192ce, rtl8192cu, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be, rtl8821ae, rtl8822be and rtl8723de in Ubuntu with DKMS (Dynamic Kernel Module Support) support. So it will work in each kernel on your system.

This may not work if you already installed the drivers and broke things up. I would recommend to do the steps in a clean install of Ubuntu desktop.

1. Connect your laptop to a wired network, and then open terminal from application menu.

2. Run command to install some required tools:

sudo apt install git build-essential dkms

Type user password (no asterisk feedback due to security reason) when it prompts and hit Enter.

3. Now grab the rtlwifi_new codes via command:

git clone -b extended

4. Add the source to the tree for builds with DKMS support.

sudo dkms add ./rtlwifi_new

5. Finally install the drivers via command:

sudo dkms install rtlwifi-new/0.6

6. If everything works OK, Wifi should work immediately (it works in my case in Ubuntu 19.04).

If not, try commands to load the new installed module (rtl8723de in the case):

sudo modprobe -r rtl8723de && sudo modprobe rtl8723de

7. And Wifi works after reboot without doing any configuration, at least in my case in Ubuntu 19.04.

If not, try command to write it into configuration file (replace 3 to 1, 2 or 4 if signal is weak).

echo "options rtl8723de ant_sel=3" | sudo tee /etc/modprobe.d/rtl8723de.conf

In addition, if you happened to update your system with newest Kernel packages without reboot. You need to reinstall the kernel packages to get the module work after reboot.

  1. Hey Ji m,
    thanks, this looks like a very good walk-through. Unfortunately, on my new HP with RTL8821CE wifi adapter, this has not yet done the trick. Still no wifi adapter found under ubuntu 18.04 (works fine under windows).
    1. I used modprobe on the rtl8821ae module (number matches my card, but ae instead of ce, no idea if that is a problem?)
    2. I noticed that no rtl8821ae.conf has been created in my /etc/modprobe.d/ directory.
    Do you have a suggestion what I could try? Thanks a lot!

  2. I owe you man. Thanks a lot for this article.
    ant_sel=2 and a reboot did the job. Signal strength is fluctuating. How can I get a fixed strength??

  3. My dell inspirion 14 does not have a ethernet port. Any way to get wifi working in this situation?
    Thank u

  4. Thanks again Ji m.

  5. Hi,

    I have a hp computer. Wifi adapter is not working. Please find the wireless infotext below

  6. For me this here worked:

    sudo apt-get install –reinstall git dkms build-essential linux-headers-$(uname -r)
    git clone
    cd rtl8821ce
    chmod +x
    chmod +x
    sudo ./
