No wifi networks are showing. I need help fixing this or safely uninstalling it

I recently got zorin is 15 and no wifi networks are showing. I need help fixing this, or help uninstalling it safely. I removed Windows, and this is the only computer I can use.

What is the terminal output of

lshw -class network

WARNING: you should run this program as super- user .
*- network DISABLED
description: Wireless interface

physical I'd : 0 bus info : pci@0000

Can you run this in terminal, then test your net connection?

sudo ifconfig wlan0 up

It may be a silly question, but is there any physical switch for network on your laptop? Also worth checking whether network card is enabled in BIOS.

No there's notz

How can I check the network card?

in terminal and look for a network related entry.

ifconfig command not found

Network controller : Realtek Semiconductor Co., Ltd. Device c822

The driver should be included in kernel 5.2 and up.

Can you type
uname -a
and tell me the kernel version?

5.4.0-47-generic #51~18.04.1-Ubuntu SMP Sat Sep 5 14:35:50 ITC 2020 x86_64 x86_64 x86_64 GNU/Linux

The kernel should support this chipset.
Did you check your BIOS settings?
WiFi adopter is usually listed under peripherals.

How can I check BIoS settings?

You have to press a certain key while switching on your machine.
The key is different from manufacture to manufacture. You have to refer to the user manual to find this special key.

Ok... try:

sudo ip link set wlan0 up

wlan0 is unknown

See... This is why the developers (Debian Stretch) should not have deprecated ifconfig without a multi-setup replacement already at the ready.

Let's try restarting your Network Manager:

sudo service network-manager restart

Nothing appears after I enters my passwor

Ok I found it. How do I get to the settings?
