I opted to install all third party drivers during installation, and have used a wired connection to update software, and check for additional drivers. Still no luck.

I then looked on here and found a similar thread that seemed to have helped one user but it failed to resolve my issue.

The posted solution was as follows:

sudo apt update

sudo apt install build-essential git dkms

git clone https://github.com/tomaspinho/rtl8821ce.git

cd rtl8821ce

sudo ./dkms-install.sh

This worked fine for me, I will post the results below:

however the original user said to follow this up with

sudo modprobe 8821ce

I cannot get this command to run, and assume at this point this is why I still have no Wifi driver. When I try to run it I get the following results.

gino@DrHappy:~$ sudo modprobe 8821ce

[sudo] password for gino: 

modprobe: ERROR: could not insert '8821ce': Operation not permitted

I tried a couple times to make sure I am not simply mistyping my password, no luck. Below here I will post a link to the original question. I tried to add this comment there but I am not allowed due to reputation limits needed for posting on that particular thread.

Lenovo Thinkpad E480 - No Wifi Adaptor Found in Ubuntu 18.04

If anyone could let me know where I am going wrong, or of another approach to getting my Wifi working that would be great.

I strongly feel that this is the issue: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1806472

"The r8822be module alias is intact, trying to modprobe it or insert
results in a "operation not permitted" error. "

I believe the bug is applicable to several other Realtek modules.

Please try disabling Secure Boot.
