Ubuntu 17

If you’re a user of Ubuntu 18.04 and have been experiencing issues with your TP-LINK Archer T3U wireless adapter, you’ve come to the right place. This guide will walk you through the steps to troubleshoot and resolve these issues.

Understanding the Issue

The TP-LINK Archer T3U is a high-speed dual band wireless adapter that provides a seamless networking experience. However, it may encounter compatibility issues with certain operating systems, such as Ubuntu 18.04, due to driver issues.

Prerequisites

Before we start, make sure you have the following:

  • A computer with Ubuntu 18.04 installed.
  • A stable internet connection (you might need an Ethernet connection if your wireless adapter is not working).
  • Basic knowledge of terminal commands.

Solution 1: Using cilynx/rtl88x2BU Repository

One of the most common solutions is to use the driver from the cilynx/rtl88x2BU repository on Github. Here’s how to do it:

  1. Clone the Repository Open a terminal and clone the repository using the following command:
    git clone https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959.git
    This command uses git clone to copy the repository from Github to your local machine.
  2. Navigate to the Cloned Directory Use the cd (change directory) command to navigate to the cloned directory:
    cd rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
  3. Compile and Install the Driver Now, compile the driver using the make command:
    make
    Then install the driver with sudo make install:
    sudo make install
    The sudo command allows you to run commands with administrative privileges, while make install installs the compiled program.
  4. Reboot Your System Finally, reboot your system to apply the changes:
    sudo reboot

Solution 2: Using jeremyb31 Repository

Another solution is to use the driver from the jeremyb31 repository on Github. Here’s how:

  1. Clone the Repository Open a terminal and clone the repository:
    git clone https://github.com/jeremyb31/rtl8822bu.git
  2. Navigate to the Cloned Directory Change to the cloned directory:
    cd rtl8822bu
  3. Remove Previous Installations If you have previously installed drivers, remove them using the following commands:
    sudo dkms remove rtl88x2bu/5.3.1 --all
    sudo dkms remove 8822bu/1.1 --all
    The dkms remove command removes any previous installations of the driver.
  4. Uninstall Manual Installations If you have manually installed the driver, uninstall it:
    sudo make uninstall
  5. Update the Repository Update the repository using git pull:
    git pull
  6. Remove cilynx If you have installed the driver from the cilynx repository, remove it:
    cd ~/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
    sudo make uninstall
  7. Install the Updated Version Now, install the updated version from the jeremyb31 repository:
    cd ~
    sudo dkms add ./rtl8822bu
    sudo dkms install 8822bu/1.1
  8. Reboot Your System Finally, reboot your system to apply the changes:
    sudo reboot

Solution 3: Disable Secure Boot

Sometimes, Secure Boot can interfere with the installation of third-party drivers. Make sure to disable Secure Boot in your system’s BIOS settings. You can usually access the BIOS settings by pressing a specific key (like F2, F12, DEL, or ESC) during the system startup.
