Ubuntu – Can’t install TP-link Archer T4U V3 driver on 19.04

19.04driverswireless

I have an Archer T4U Wi-Fi adapter but I can't install the drivers. Could someone please help me?

lsusb gives out this result:

Bus 006 Device 003: ID 2357:0115 TP-Link 

When I try to compile it with make, the following error shows up:

As far as I know this USB Wifi Card is based on Realtek RLT8822BU Chipset.

On support page I only see "outdated" drivers T4U V3 180511 and T4U V3 181018 Beta, may they work, may not.

I would try to use driver from https://github.com/brandon-bailey/rtl8822bu and compile it.

sudo apt-get update
sudo apt-get install git
git clone https://github.com/brandon-bailey/rtl8822bu.git
cd rtl8822bu
make
sudo make install
sudo modprobe 8822bu
