This article is about to install the "Wi-Fi driver" of EW-7611ULB v2 adapter in Ubuntu 22.04 Kernel v5.15.0. (The procedure is also confirmed in Mint 21 Kernel v5.15.) As of May 2023, the official Ubuntu driver on our website can only support kernel up to v5.11. Therefore, we use the Wi-Fi driver on GitHhub at https://github.com/lwfinger/rtl8723du. Thanks to lwfinger.
We recommend you check lwfinger's site for updated information and driver names.
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.
Here is a brief instruction for your reference.
[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 of your Ubuntu.
$ uname -r
[4.] Make your system up-to-date. This step is optional but recommended.
$ sudo apt update
$ sudo apt upgrade
$ sudo reboot
[5.] Install the essential files to compile software.
$ sudo apt install make gcc build-essential git
[6.] Install the kernel headers.
$ sudo apt install linux-headers-$(uname -r)
[7.] Download the open source driver
$ mkdir -p ~/src
$ cd ~/src
$ git clone https://github.com/lwfinger/rtl8723du.git
$ cd rtl8723du
[8.] Compile and install the driver.
$ make
$ sudo make install
If you enabled SecureBoot in BIOS,
$ sudo make sign-install
[9.] Restart your system for the newly installed driver to take effect.
$ sudo reboot
[10.] Plug in EW-7611ULB v2 adapter if you haven't done so.
Unplug the Ethernet cable since it is not needed any longer.
[11.] Go to Network icon to make wireless connection.
If you need BT function of EW-7611ULB v2, you may try the official Edimax driver on our website. Here is the BT installation instruction for your reference.
