Install the wireless network card rtl8192fu driver under ubuntu20.04/18.04

    It is troublesome to install the wireless network card on Ubuntu, which is different from the driver under windows, and the driver CD compared by the manufacturer does not have the driver under the linux system. You can only refer to the information on the Internet to install. The following is my installation process.

Wireless network card driver link:

https://github.com/Mange/rtl8192eu-linux-driver

git clone https://gitee.com/BrightXu/rtl8192fu.git

1. Download and decompress the driver code package rtl8192fu-master.zip

    unzip rtl8192fu-master.zip

2. Enter the directory rtl8192fu-master and compile and install the driver

   (1). cd rtl8192eu-master
   (2). Modify MakeFile, comment out #EXTRA_CFLAGS += -Wno-error=date-time
   (3). make
   (4). sudo make install

3. Load the driver

sudo modprobe 8192fu
lsmod
to see if the 8192fu driver module is listed

4. Confirm whether the driver is installed correctly

(1).
If there is wlan0 information in sudo iwconfig, the installation is successful.

5. Configure the network link through the network manager

System Settings-->Network-->Wireless-->Network Name, select the router to log in and enter the secret login.

6. Add the driver to the boot list

sudo -i
echo 8192fu >> /etc/modules

When your system is ubuntu18.04, if you encounter a wireless network card driver, please refer to the following method:

Finally, check whether the wifi driver is mounted successfully;

When the wireless network card is plugged in, ubuntu will recognize the wireless network card, and you can go online normally.
