Network Unclaimed Zorin os 15 core

Suddenly my wifi stopped working. I am using zorin os based on ubuntu 18.04.

A recent kernel update may have given you the 5.4.0-87 kernel. If so, and if you had installed the Wifi Driver manually without DKMS, then any kernel update may cause the driver to no longer hook into the modules.
DKMS helps prevent this by using the module prober for you, as long as the driver and kernel version support eachother.

Can you please try:

sudo apt install git dkms

git clone https://github.com/aircrack-ng/rtl8812au.git

cd rtl8812au

sudo make dkms_install

I could be wrong but OP's post said:

RTL8822BE

I thought those are different products.

It's very confusing... Very. You will find 18 or so devices listed under one set of drivers labeled for only one of those devices. I have never figured out the logic of it- maybe because there is none.

The drivers work across several models and get clumped together into one driver set. The above github source contains drivers that work on the OP's device. Naming conventions could use some work.

Ah, I see. I did not know.
Thanks for the explanation!
