First time user ; No Wi-Fi Connectivity

[Kujo]

Hey all, I installed 4.4 (first time Linux user, new to forum etiquette as well, so correct me as needed ) onto my Lenovo Ideapad S145 and I can't find any networks on Wi-Fi. My only option at the moment is the tethering hotspot on my phone. When I try to install drivers it says there are no additional drivers , and I can't find any way to interact with or install proprietary drivers.
In the BIOS menus I switched from UEFI to Legacy so I don't even have the option to turn off Secure Boot ( When I switch to UEFI with Secure Boot turned off I get an error basically saying there's nothing to boot).

Trying to figure out what I should try next. If I'm leaving out any info I'll gladly provide, just may need some help with pulling it up for you!

Thanks in advance!

Since you installed Linux Lite 4.4 and if you are able to get to the desktop and open the terminal window, type the following and see if it helps.
sudo ubuntu-drivers autoinstall 
sudo reboot

Went ahead and tried that, got a message saying "No drivers found for installation."

Go to this link and see if your driver is there.

I cannot tell from your post if you had UEFI and Secure Boot turned off before or after the installation.  If you're not using the UEFI image file, those things need to be turned off before the installation.  Assuming you installed correctly, type the following into a terminal and share your results:

Code:

inxi -F

Turns out my card is a Realtek RTL8821CE. I think i found a zip file for the driver on Github but I'm not sure how to install it yet...

I used the following four commands in the terminal to install the driver.  Worked perfectly.
Assuming you already have the driver stored on your computer -

Open the terminal and enter following:

The first command is to change directories to the location of your rtl8821ce driver.  As an example, the line below is what I used on my computer, change it to match whatever path yours is on. After entering each command hit the enter key.
 
cd /home/richard/rtl8821ce
sudo ./dkms-install.sh
sudo modprobe 8821ce
iwconfig

After entering these commands (with no errors) you should be able to click on your network icon and find your wi-fi network.

Came back to say this did the trick. Thank you to everyone who pitched in to help me out!
I'll go ahead and mark the thread solved.
