TP-LINK Archer T3U not working in Ubuntu 18.04

Question

I recently acquired the TP-LINK Archer T3U. I tried several solutions, but it still does not work. I tried with https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959/ and https://github.com/jeremyb31/

Results of sudo lshw -class network :

is the device Bus 003 Device 002: ID 2357:012d

then I checked rfkill list all and is not hard or soft blocked, and dmesg did not throw and error.

Thanks in advance

Answer 1

I have just recently updated https://github.com/jeremyb31/rtl8822bu to support this device Make sure the other dkms modules are gone

sudo dkms remove rtl88x2bu/5.3.1 --all
sudo dkms remove 8822bu/1.1 --all

Remove any possible manual installs using make

cd rtl8822bu && sudo make uninstall

Update the git

git pull

Remove cilynx

 cd ~/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959 
sudo make uninstall

Install updated version from https://github.com/jeremyb31/rtl8822bu

cd ~
sudo dkms add ./rtl8822bu
sudo dkms install 8822bu/1.1

Reboot

Answer 2

Create a file in ~/Downloads called install_t3u.sh with the following content:

#To run script, type 'sudo ./install_t3u.sh' in ~/Downloads/
##This bash-script assumes your CPU has eight-threads.

sudo dkms remove rtl88x2bu/5.3.1 --all;
sudo dkms remove 8822bu/1.1 --all;

cd ~/Downloads/;
git clone https://github.com/jeremyb31/rtl8822bu;
cd rtl8822bu/;
make uninstall -j 8;
make -j 8;
make install -j 8;
cd ../;
sudo cp -R rtl8822bu/ /usr/src/.-rtl8822bu/;
sudo dkms add ./rtl8822bu;
sudo rm -R rtl8822bu/;
echo "Install completed. Please reboot.";
echo "Try: 'sudo shutdown -f now' or 'reboot'";

While in same directory, execute sudo ./install_t3u.sh

Answer 3

I'll add one more answer because the accepted one didn't work for me with Debian 10 (a distro which Ubuntu solutions work most of the time).

I cloned this repo: https://github.com/cilynx/rtl88x2bu and followed the instruction in the readme.

Here is a summary of the commands I used

git clone https://github.com/cilynx/rtl88x2bu
cd rtl88x2bu
make
# I tested the module with this
sudo insmod 88x2bu.ko
# and then wifi worked!

# Then to make the module available after reboot
./deploy.sh
