TP LINK AC1200 t4u for ubuntu 16.04

[ashish.patel11ee211]

I would like to say that I tried a lot for this USB adapter installation.

Here I put every single link. From where I took references.

First I tried:

http://www.tp-link.com/en/download/Archer-T4U.html

second I tried:

https://www.amazon.com/product-reviews/B00JBJ6VG8

on this page one comment is Linux Installation for this device is not trivial, needs work.

third I tried:

https://ubuntuforums.org/showthread.php?t=2264741

then I tried:

https://github.com/ptpt52/rtl8812au

Still, I don't get the satisfied answer. Please help me and give me step by step answer if possible.

So what are the results from

lsusb

with the device not plugged in?

[chili555]

With a working internet connection, please do:

sudo apt-get purge rtl8812au-dkms

If it isn't installed, that's fine; just continue:

sudo apt-get update
sudo apt-get install git dkms
git clone  https://github.com/ptpt52/rtl8812au.git
cd rtl8812au
sudo make -f Makefile.dkms install
sudo modprobe rtl8812au

You should be all set.

I followed every step but then I got this error:

The quick and easy way is to disable secure boot in the BIOS.

You can disable Secure Boot (UEFI) in the BIOS with the following steps:

1. Reboot your machine and enter the BIOS Menu (In my case pressing F2)
2. Search for Secure Boot and change to Legacy

[ashish.patel11ee211]

It's working. Thanks, man. I didn't try on legacy mode. Thanks once again

[chili555]

Glad it's working! Please use thread tools at the top to mark Solved. The searchers will appreciate it.
