Driver Installation for TP Link Archer T3U Plus AC1300 USB Wifi Stick - dividebysandwich/shareboxx GitHub Wiki

While the TP-Link Archer T3U Plus features excellent range, it is not fully supported out of the box in most linux distros, including Raspi OS. The problem is that connecting to the generated Wifi Access Point fails after a few seconds. To fix this, you have to install a driver.

The driver's source repo is located at https://github.com/morrownr/88x2bu-20210702

The following commands should get the driver installed on your Raspberry Pi:

sudo apt update && sudo apt upgrade
sudo apt install -y raspberrypi-kernel-headers build-essential bc dkms git
git clone https://github.com/morrownr/88x2bu-20210702.git
cd 88x2bu-20210702
sudo ./install-driver.sh

After rebooting, the Shareboxx access point should start working.
