This article is to demonstrate how to install the EW-7822ULC/UTC AC1200 USB 2.0/3.0 nano/mini adapters on Raspberry Pi(RPi) running Raspbian Operating System(OS). In this example, we have Raspbian(11, bullseye) running kernel version 5.15.32 with a Raspberry Pi 2 model. The instruction also confirmed work with Buster version 5.10.
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.
We use the Realtek RTL88x2BU driver on https://github.com/morrownr/88x2bu-20210702
You are encouraged to check the latest installation instruction on morrownr site.
[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.] Install Headers and other essential functions
$ sudo apt-get install raspberrypi-kernel-headers bc build-essential dkms git
[6.] Create subfolder and clone the open source driver from GitHub
$ mkdir -p ~/src
$ cd ~/src
$ git clone https://github.com/morrownr/88x2bu-20210702.git
$ cd 88x2bu-20210702
[7.] Modify the hardware platform in Makefile. The default setting of the driver is for Intel/AMD-based (I386-PC) platform. We have Raspberry Pi 2 model so we change the settings to ARM-based platform. If you have Raspberry Pi 3/4, you can change the CONFIG_PLATFORM_ARM64_RPI settings.
$ sudo nano Makefile
[ Note: nano is my Text Editor of choice. You can use any one you preferred like vi. ]
-- Change the following lines:
CONFIG_PLATFORM_I386_PC from y to n
CONFIG_PLATFORM_ARM_RPI from n to y
-- Save the file
[8.] Compile and install the driver
$ make
$ sudo make install
[9.] Reboot Raspberry Pi
$ sudo reboot
[10.] Click the Network Manager icon on the top right menu bar. Connect to your wireless network.
Enjoy!
