If you're experiencing issues with your USB WiFi adapter on Kali Linux, you're not alone. After a recent upgrade, my adapter stopped working. Here's how I resolved the issue by installing a different driver.

Step 1: Remove the Old, Defective Driver

First, identify and remove the old driver.

1. Get the status of the old driver:

   
   sudo dkms status
   

2. Remove the old driver:

   Replace `old-driver-name` with the actual name of your old driver

   sudo dkms remove -m old-driver-name --all

Step 2: Install a Newer Driver

Next, install a newer driver.

1. Clone the Repository:

   git clone https://github.com/morrownr/8821au-20210708.git

2. Navigate to the Directory:
   
   cd 8821au-20210708

3. Install the Driver:

   sudo ./install-driver.sh

note: after finishing the installation it will ask you if you want to modify the configuration, i didn't change anything. after exiting the configuration file it will ask for a reboot.

Step 3: Reboot
Reboot your system to apply the changes.

Hopefully, this solution will work for you!
