Any solution anyone?

I am sorry I have been multi-tasking a lot and I was not very clear.

DKMS is a method by which you can install a manually-installed driver, that patches it into the kernel when the kernel upgrades. Since your driver was not recognized by the kernel, my thought was to install the driver through dkms.
I see you have opened a new thread on reverting the driver, though.

my driver is now previous one and now wifi connects but the speed is very slow....................................

26

I wonder if this video tutorial may help.

I think i found the correct driver for you. According to the internet The RTL8821AE and the RTL8821CE use the same driver.

  2. Unzip it in somewhere in your HOME directory.
    Example: Downloads/rtl8821

  3. Open terminal and move to the working directory:
    cd Downloads/rtl8821

  4. Compile and install (one line at a time)

I will ask @Aravisian
He is way more knowledgeable than myself for such matters.

The make command failed and the driver will not install.

First, ensure secure boot is disabled. This is a Must.

In this case, it is the driver developer that has made the error, not the Kernel team. The driver should show solid support across distributions.
You might try:

sudo apt install dkms git bc module-assistant build-essential gcc gcc-c++ kernel-headers and kernel-devel

And then try running make in your driver directory again. If it succeeds without errors, great. If not, let's abandon that driver as the next step would require you to patch the kernel and it's not the best way to go about this.

I should remember this one.
I've never enabled secureboot myself but some people might be using it.

You could try running
sudo apt update
before issuing those commands.
