As of July 2023, the Official Linux drivers on edimax.com website support Linux kernel up to v5.4.   This instruction is done on an Ubuntu 20.04 installation with kernel v5.4.


First of all, please make sure the "Secure boot" is disabled in BIOS.  If you are not sure how to do that, you need to find out how to get into the BIOS settings of your computer.

 

[1.]  Make sure your system is able to access the Internet. 


[2.]  Open a Terminal program from your Ubuntu OS. 


[3.]  Verify the kernel version in your Ubuntu Linux. 

$ uname –r 

If your kernel is newer than v5.4, stop here.  The instruction may not work for you.  You will need to use third party driver.

 

[4.]  Download the Linux driver of EW-7811Un v2 on http://www.edimax.com site.   

Pay attention on the supported kernel of the Linux driver.  The driver can be updated to support newer kernel.

The downloaded file is a zip file and saved in your Downloads folder.

Go to /Downloads folder and extract the file.

 

[5.] Update system.

Make sure your system is up-to-date and reboot it after updated/upgraded, especially with a kernel update.  This step is optional but recommended.  Do the following commands under the terminal window.

$ sudo apt update

$ sudo apt upgrade

$ sudo reboot


[6.]  Install the header and necessary files. Do the following commands under the terminal window. 

$ sudo apt install linux-headers-$(uname –r)

$ sudo apt install build-essential make 


[7.]  Go to Files Manager.  Go to the /Downloads folder.  Right-click on the driver EW-7811Un_V2_Linux_Driver_1.0.1.3 folder.  Select "Open in terminal". 


Alternatively, you can use below command under terminal to go to the driver folder directly. 

$ cd Downloads

$ cd EW-7811Un_V2_Linux_Driver_1.0.1.3

 
[8.]  Compile the driver.   

$ make

 

 [9.]  Install the driver

$ sudo make install

 

[10.]  Reboot system

$ sudo reboot


[11.]  The Wi-Fi option is available on the network manager.  You can find your wireless connection.

 

Congratulations!  The setup is complete.


 

Note.  If you update your Ubuntu with unsupported kernel, the driver may no longer work. You may need to get different driver. Before installing a new driver, please remove the old one using the following commands.

 

[1] Go to Terminal window.

[2] Change folder to the Driver subfolder in Downloads.  for example, EW-7811Un_V2_Linux_Driver_1.0.1.3 directory.

$ sudo make uninstall

$ make clean

$ sudo reboot
