Installing AC1300 T4U v3 usb wireless adapter

I’m using a ReComputer J1020, and trying to install the AC1300 T4U v3 usb wireless adapter driver from https://github.com/cilynx/rtl88x2bu using:

cd rtl88x2bu-5.8.7.1_35809.20191129_COEX20191120-7777
VER=$(sed -n ‘s/\PACKAGE_VERSION=“(.*)”/\1/p’ dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

Running

sudo dkms build -m rtl88x2bu -v ${VER}

gives

Kernel preparation unnecessary for this kernel. Skipping…

‘make’ -j 4 KVER=4.9.299-tegra src=/usr/src/rtl88x2bu-5.8.7.1…(bad exit status: 2)

Then

more /var/lib/dkms/rtl88x2bu/5.8.7.1/build/make.log

gives

I think the issue might be aarch64/amd64 confusion. I tried

export ARCH=arm64

at the command line but no joy.

What is wrong?

(I have a fair amount of computer and programming experience, not a huge amount with Linux but I can normally get by. I have the same wireless adapter running fine on an old HP laptop running Ubuntu 22.04).

Many thanks!

For anybody else trying to do this…

The TP-Link AC1300 v3 (Archer T4U) needs the ‘BU’ driver (the earlier versions used the ‘AU’).

I used the version by jeremyb31 at GitHub - jeremyb31/rtl8822bu: RTL8822BU Wireless Driver for Linux - it respects the export ARCH=“arm64” directive, and compiles correctly

  • Download the zip file and unzip it
  • cd into the directory
  • Issue the export ARCH=“arm64” directive
  • Follow the instructions in the README.md file
  • Reboot

Thanks for the sharing.
