My wifi card is not detected on Realtek Semiconductor Co., Ltd. Device a85a Ubuntu 20.04.3. I have tried all kinds of different threads that have a similar problem and nothing has worked. I get the following message:

0000:02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device a85a

A teacher told me he thinks the "blob" is missing but I don't know what that means.

Here are some commands I have tried:

sudo modprobe rtw89pci
modprobe: FATAL: Module rtw89pci not found in directory /lib/modules/5.11.0-43-generic***

Is there something I can do to solve it? I've been trying to solve this problem for 2 months now and I'm a bit desperate.

THANK YOU FOR THE HELP

First of all, the correct driver for your device is indeed rtw89pci. Let's start from the beginning. With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

sudo apt update
sudo apt install git build-essential bc

Next, follow this process exactly: How to get Realtek RTL8852AE WiFi card to work on my new laptop

If applicable, you will have to disable Secure Boot.

Reboot and your wireless should now be working.
