LinkSys AC1200 Wireless-AC USB adapter install

Question

Purchased a USB adapter( LinkSys AC1200 Wireless-AC USB adapter/ model WUSB6300) for my Windows laptop and the installation on that was easy. Tricky part is getting it to work in my Linux environment laptop. Cisco does not support Linux with this device.Need to figure out if I can install this to my Linux environment somehow. Some details:

Ubuntu:             14.04 LTS  
lsusb:              Bus 002 Device 004: ID 13b1:003f Linksys  
Hardware at Issue:  LinkSys AC1200 Wireless-AC USB adapter  
model:              WUSB6300

Solution

This can be done on a command line terminal:

This is a brand new device which needs a separate driver. Install it via LAN connection:

sudo apt-get install linux-headers-$(uname -r) linux-headers-generic build-essential git
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux
cd rtl8812AU_8821AU_linux
make
sudo make install

Load the driver and check:

modinfo 8812au | egrep -i 'versi|filen|003f'
sudo modprobe -v 8812au
iwconfig
iwlist chan

Do not remove the driver folder. After a kernel update you need to compile again:

cd rtl8812AU_8821AU_linux
make clean
git fetch
git reset --hard origin/master
make
sudo make install

Be aware, that git fetch requires internet access to fetch driver updates from its source code repository, so you may want to do that before booting the new kernel.

sorry, noob here to Linux. Is this a command to enter into terminal?

[David Foerster]

Yes. I clarified that in the answer.

Your solution works perfectly. Just bought this adapter and this kept me from returning it.

In my case modinfo 8812au | egrep -i 'versi|filen|003f' returned modinfo: ERROR: Module 8812au not found. I found using lsmod | grep 8812au that I got a result called rtl8812au rather than 8812au. Using rtl8812au rather than 8812au in the first two "Load the driver and check" lines did the trick. Ubuntu 16.04.

@David Forester after restarting it's not working anymore... any ideas?
