I just bought a new USB stick and succeeded in doing this-
as you can probably tell this is the status of the machine that is giving me problems getting online. Will installing wifi drivers solve my issues?

I am uncertain about what to download. Is this the correct file?

https://aur.archlinux.org/rtl8821ce-dkms-git.git (read-only)

Or this hypertext link?

rtl8821ce-dkms-git

I just don't understand how the user repository works. I want to download the drivers for my wifi, write it to a USB stick and then transfer it to the Mint install on my desktop. I said that to remind myself what I am doing and to tell you as well.

Only a Moderator can remove a post.

Try not to double post if at all possible.

Download the zip file from here and put it on your usb stick.

https://github.com/tomaspinho/rtl8821ce

Go over to your Mint machine with the fresh install that you're having trouble getting the wifi to work and plug the usb stick in.
Cut and paste that rtl8821ce master.zip file into your Downloads directory.

Unzip the file and than locate the rtl8821ce master file and open it.
Read the "ReadME" file for the instructions on how to install the driver.

Make sure dkms is installed and follow the Ubuntu instructions to install the driver.

I went to the gethub site. I see a list of files but nothing says zip. Also about the dkms. Must I also download that and save it to the USB stick?

Click on the green box that says 'clone or download'

Just find out if dkms is installed first. To do that run this in the terminal:

Thanks brother. I will have to sign off on this machine first. I'm on the window os of the same machine mint is on.

Do I unzip the file before I save it to USB?
I went ahead and unzipped it to the USB stick.

No don't unzip it until you transfer it to your Linux Mint installation.

Oh oh.. to late. I unzipped it directly to the usb stick. Now what do I do?

Re-download it to your Windows system. Than cut it and paste it to your usb stick.

I know how to cut and paste text. How do I go about doing that with this file?

I have re-downloaded it. Now about that cut and paste thing?

I went to the downloads folder and dragged the unzipped file to the usb. I think I have there now. I now have two files on the USB stick. One says master the other master.zip. I recon I use the master.

Cut the file "rtl8821ce master.zip" and paste it to your usb stick.
Boot into Mint and unzip it.
After you unzip it it will than change to rtl8821ce master click on that and read the "README" file.

Run this command and post back the results that the terminal returns please.

And hit Enter.
