I am experiencing problems with the TP-Link AC1300 Archer T4U on Ubuntu 20.04. Can anyone provide guidance or solutions for resolving incompatibility or connection issues with this Wi-Fi adapter?

I’ve been pulling my hair out trying to get my TP-Link AC1300 Archer T4U to work with my Ubuntu 20.04 setup. I’m not exactly a Linux guru, but I thought switching to Ubuntu would help me get away from the typical Windows mess. However, now I’m facing this headache with this Wi-Fi adapter.

First off, the adapter seems to be recognized by the system, but I can’t connect to any Wi-Fi networks. In the network manager, it shows that the device is available, but whenever I try to connect, it just hangs and throws an error saying it can’t find the network. I’ve tried rebooting multiple times, unplugging the adapter and putting it back, and even running some updates, but nothing seems to work.

I did some digging online and noticed that there might be some driver incompatibility with this model on Ubuntu, which is super frustrating. When I checked the additional drivers section in settings, it only shows proprietary drivers for my graphics card and nothing for the TP-Link adapter. Shouldn’t there be something for the Wi-Fi? I also tried connecting to my router using a different device and it’s working perfectly fine, so I’m pretty sure it’s not an issue on the router’s end.

Has anyone else gone through this kind of trouble? Maybe someone out there has a workaround or a driver they recommend? I came across some threads suggesting I might need to compile a driver or use the terminal for some kind of installation, but I’m honestly not sure where to start without breaking something in the process. If anyone has a step-by-step guide or a simpler solution, I would totally appreciate it!

I’m really hoping to get this sorted out because without Wi-Fi, my Ubuntu experience is kinda limited. Any insights from fellow Ubuntu users or those who have dealt with this specific TP-Link adapter would be a lifesaver. Thanks!

    1. If your TP-Link AC1300 Archer T4U is recognized but you’re unable to connect to Wi-Fi networks on Ubuntu 20.04, it’s likely due to driver compatibility issues. While you mentioned checking the additional drivers section, the lack of an option for your Wi-Fi adapter suggests that the required drivers may not be included out-of-the-box. Many TP-Link adapters rely on specific drivers that may not automatically install with the Ubuntu kernel. You may need to obtain the appropriate drivers manually, which can often be found on the TP-Link website or from community resources. Importantly, ensure your system is updated and that you have the necessary build tools installed by running `sudo apt update` and `sudo apt install build-essential dkms`. This will prepare your system for installing the driver if you choose to compile from source.

      To install a driver, you might follow these general steps: First, download the driver source code from a reliable repository like GitHub (e.g., jeremyb31/rtl8821AU is one example). Extract the files and navigate to the extracted directory in the terminal. Then, run `make` and `sudo make install` to compile and install the driver. After installation, use `sudo modprobe ` to load the driver. You should replace `` with the driver you’re installing (e.g., `8812AU` or `8821AU`). Finally, restart your machine and check if your adapter connects to your Wi-Fi networks. Be cautious with these steps; any mistakes might necessitate manual removal of the driver, so always refer to installation instructions provided in the driver documentation. If you encounter issues, forums like Ask Ubuntu and Ubuntu Forums are great places to find user-specific solutions and troubleshooting tips.

      Help with TP-Link AC1300 Archer T4U on Ubuntu 20.04

      Ah, the struggle is real! I’ve been there too with Wi-Fi adapters on Ubuntu. So, here’s a few things you might wanna try:

      1. Check for Updates

      Make sure your system is fully up-to-date. You can do this by running:

      sudo apt update && sudo apt upgrade

      2. Install Required Packages

      Sometimes, you might need some packages to get these drivers working. Open your terminal and paste this:

      sudo apt install build-essential dkms git

      3. Check for Drivers

      Try checking for additional drivers specifically for your Wi-Fi adapter. Go to Software & Updates > Additional Drivers. If nothing shows, you may need to get a driver from GitHub.

      4. Download the Driver

      If you need to compile a driver, follow these steps (it’s not too scary!):

      • Open the terminal and run:
        • git clone https://github.com/yourdriverrepo
      • Navigate to the downloaded directory:
        • cd yourdriverrepo
      • Now compile & install the driver:
        • make && sudo make install
      • Finally, reboot your system.

      5. Check Your Network Settings

      Make sure your Wi-Fi is enabled in the settings, and double-check that you’re not trying to connect to a hidden network.

      6. Use `modprobe` Command

      You can also try loading the driver manually using:

      sudo modprobe your_driver_name

      7. Reach Out!

      If all else fails, hitting up forums like Ubuntu Forums or Ask Ubuntu can help. Just remember to mention your adapter model and what you’ve already tried!

      Good luck! You’re not alone in this Wi-Fi adventure!
