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). In this example, we have Raspbian(11, bullseye) running kernel version 5.15.32.
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

$ sudo apt upgrade
$ sudo reboot
[5.] Install Headers
$ sudo apt-get install raspberrypi-kernel-headers
[6.] Install Network Manager
$ sudo apt install network-manager network-manager-gnome
[7.] Clone the open source driver from GitHub
$ git clone https://github.com/lwfinger/rtl8188eu.git
