This article is to show how to install the EW-7811Un v2 N150 USB 2.0 nano adapter on Raspberry Pi(RPi) running Raspbian Operating System(OS) with pre-compiled third party Linux driver. In this example, the Raspbian(10, Buster) running kernel version is 4.19.66.
Please note the pre-compiled driver on the third party website may not work with the newer OS Bullseye. If you have kernel v5.10.92 or later, you may refer this different instruction.
Everything will be done in a Terminal program. The commands are in green below. The characters '$' and '#' are just the prompt to indicate you're either a regular or the root user. You don't need to include them with the commands, i.e. do not type them. You should input the commands one at a time.
[1.] Make sure your RPi is able to access the Internet.
[2.] Open a Terminal program from your Raspbian OS.
[3.] Check your kernel version.
$ uname -r
[4.] Make sure your system is up-to-date. A reboot may be needed if the kernel has been updated.
$ sudo apt update
$ sudo apt upgrade
$ sudo reboot
[5.] Visit the Fars Robotics website at http://downloads.fars-robotics.net/wifi-drivers/8188eu-drivers/
Look for the correct driver for your kernel version.
Since our Raspbian buster has kernel 4.19-66-v7+, we click and download the file 8188eu-4.19.66-v7-1253.tar.gz
[6.] Right-click on the downloaded file. Select Extract to and extract the file.
[7.] Right-click on install.sh file, click on Open. Select Execute on Terminal.
[8.] Restart your system for the newly installed driver to take effect. After reboot, the wireless function would be available.
In case you prefer to type commands under terminal,
$ wget http://downloads/fars-robotics.net/wifi-drivers/8188eu-drivers/8188eu-4.19.66-v7-1253.tar.gz
$ tar xzf 8188eu-4.19.66-v7-1253.tar.gz $ ./install.sh
$ sudo reboot
Enjoy!
