(This question is a duplicate of Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE) but I was pleased that we eventually found a solution so will write up what worked for Haz.)
As far as I can tell, at the time of writing this, there is not yet a Wifi Driver for the Realtek RTL8821CE in the official Ubuntu Repositories.
Over on github there is a repository with an RTL8821CE driver aimed at kernels 4.14 and above and specifically for Arch Linux with no support provided for other Linux Distros: https://github.com/tomaspinho/rtl8821ce
(Minor note: as of February 2019 tomaspinho is sadly no longer able to maintain the driver as he no longer has access to a computer with this chipset, and so a new maintainer may be needed, but the driver still works with Ubuntu 18.04 as at that time.)
It has, however, been reported to work just fine with Ubuntu 18.04.
The solution is taken directly from post #4 by Praseodym: https://ubuntuforums.org/showthread.php?t=2398917 and will install a number of packages for building the wifi driver module (git, dkms, build-essential & linux-headers) and clone the git repository from tomaspinho.
DKMS is used because it's "a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated."
Open up a terminal and type the following lines (You can cut and paste if you prefer):
sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
sudo ./dkms-install.sh
After this is completed successfully, you should reboot and find that your Wifi is working.
You also want to make sure SecureBoot is Disabled in the BIOS settings or it won't let you load the unsigned self-complied kernel module.

The commands in the post just before this were correct except for the git pull. There is a username and password authentication requirement so you have to just go to the webpage -- https://github.com/tomaspinho/rtl8821ce -- and download the .zip file. I then tried following through with changing the shell files to executable as suggested but when they ran there was a discrepency as to where the files needed to be located. (Im definitely not complaining, it can just be a bit confusing if you didn't really know what you were doing) The files need to be extracted to /usr/src/rtl8821ce-1.0.0 (make a new directory "rtl8821ce-1.0.0" inside /usr/src) and THEN chmod +x dkms-install.sh, everything should work out like gravy from there.
Thank you so much whoever wrote this script. I dumped about 600 dollars into this badass machine and was thinking the wifi wouldn't work. Cheers.
To be specific, the machine is a new HP Pavilion x360 2-in-1 with windows 10 and ubuntu studio 18.04.

(This question is a duplicate of Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE) but I was pleased that we eventually found a solution so will write up what worked for Haz.)
As far as I can tell, at the time of writing this, there is not yet a Wifi Driver for the Realtek RTL8821CE in the official Ubuntu Repositories.
Over on github there is a repository with an RTL8821CE driver aimed at kernels 4.14 and above and specifically for Arch Linux with no support provided for other Linux Distros: https://github.com/tomaspinho/rtl8821ce
(Minor note: as of February 2019 tomaspinho is sadly no longer able to maintain the driver as he no longer has access to a computer with this chipset, and so a new maintainer may be needed, but the driver still works with Ubuntu 18.04 as at that time.)
It has, however, been reported to work just fine with Ubuntu 18.04.
The solution is taken directly from post #4 by Praseodym: https://ubuntuforums.org/showthread.php?t=2398917 and will install a number of packages for building the wifi driver module (git, dkms, build-essential & linux-headers) and clone the git repository from tomaspinho.
DKMS is used because it's "a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated."
Open up a terminal and type the following lines (You can cut and paste if you prefer):
sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
sudo ./dkms-install.sh
After this is completed successfully, you should reboot and find that your Wifi is working.
You also want to make sure SecureBoot is Disabled in the BIOS settings or it won't let you load the unsigned self-complied kernel module.

The commands in the post just before this were correct except for the git pull. There is a username and password authentication requirement so you have to just go to the webpage -- https://github.com/tomaspinho/rtl8821ce -- and download the .zip file. I then tried following through with changing the shell files to executable as suggested but when they ran there was a discrepency as to where the files needed to be located. (Im definitely not complaining, it can just be a bit confusing if you didn't really know what you were doing) The files need to be extracted to /usr/src/rtl8821ce-1.0.0 (make a new directory "rtl8821ce-1.0.0" inside /usr/src) and THEN chmod +x dkms-install.sh, everything should work out like gravy from there.
Thank you so much whoever wrote this script. I dumped about 600 dollars into this badass machine and was thinking the wifi wouldn't work. Cheers.
To be specific, the machine is a new HP Pavilion x360 2-in-1 with windows 10 and ubuntu studio 18.04.

Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
Would you like to answer one of these unanswered questions instead?
Hi Haz - this question will probably be marked as a duplicate to this askubuntu.com/questions/1067286/…. On the plus side the
sudo lshw -C network
output is almost identical to yours so you're not the only one having trouble with a realtek wifi card, but on the minus side there are no answers to the question yet...– pHeLiOn
Sep 2 '18 at 7:27
@pHeLiOn Oh thanks, but yeah that question was posted 12 days ago and still has no answer so I'm really hoping someone here can help because I'm at a loss of what to do next.

Sep 2 '18 at 7:41
Let's see if we can find the specific name of the wireless card and then search for solutions - please run
lspci -nnk | grep -A2 0280
and show that output in your question.– pHeLiOn
Sep 2 '18 at 7:48
Someone elsewhere also suggested going into BIOS settings and making sure Secure Boot is Disabled. Easy to try, so worth a shot.
