Trying to install drivers for a TP-LINK AC-600 USB Wireless adapter, failing

Hi everyone,

Outcome sought

Drivers that work on the Nano under Ubuntu Linux for the rtl8812au chipset used by the TP-LINK AC600 adapter

I’m using the Jetson Nano with the Ubuntu 18.04 LTS image;

kathyreid@kathyreid-jetson-nano:~$ uname -a
Linux kathyreid-jetson-nano 4.9.140-tegra #1 SMP PREEMPT Thu Jun 25 21:25:44 PDT 2020 aarch64 aarch64 aarch64 GNU/Linux

I need to connect the Jetson Nano to a WPA-PEAP authenticated network on the 5Ghz band. I’ve purchased a TP-LINK AC-600 USB wireless adapter for this purpose, but I cannot get drivers installed on the Nano. I am comfortable hand-editing wpa_supplicant.conf if required, but we haven’t got to that yet.

Diagnostics that show this is likely a driver issue

  • output of lsusb shows the USB Wireless adapter as Bus 001 Device 003: ID 2357:011f
  • Looking this up it uses a Realtek rtl8812au chipset
  • No wireless connection information is shown in Network Manager
  • attempts to bring up the wireless interface show no device detected
kathyreid@kathyreid-jetson-nano:~$ sudo ifconfig wlan0
wlan0: error fetching interface information: Device not found
kathyreid@kathyreid-jetson-nano:~$ sudo ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device
  • There are no wifi-ish modules loaded as shown in lsmod:
kathyreid@kathyreid-jetson-nano:~$ lsmod

The output from nmcli also confirms no wireless interface is found:

        ethernet (r8168), 00:04:4B:E6:83:5C, hw, mtu 1500

So, now I’ve established it’s a driver issue, which drivers have I tried?

Issues with various drivers

There are several rtl8812au drivers available on GitHub, but they are all failing in various ways.

This appears to be related to this GitHub issue.

I tried this again after editing the Makefile so CONFIG_PLATFORM_ARM_NV_NANO = y, but this still failed.

Any other ideas / advice / drivers that actually work?

Hi Kathy,
I found this answer

    sudo apt install git dkms
    git clone https://github.com/aircrack-ng/rtl8812au.git
    cd rtl8812au
    sudo ./dkms-install.sh

that worked for me at

With the default Tegra-Nano disk image “sd-blob-b01.img” and using the above commands I was about to build and install the drive. Through the GUI I joined my phone hotspot and download some GitHub webpages. Range is limited and I have not tested throughput nor stability.

I hope this works for you.
Regards
Kelly

Yeah, I had the same situation with Jetson Nano and TP LInk T2U. This driver perfectly works.
