Ubuntu – How to install an ASUS USB-AC56 WiFi adapter


I'm trying to get this ASUS USB-AC56 adapter installed on Ubuntu 12.04, but when I try to extract the Linux file from the cd, it says I don't have the right permissions to extract. I tried downloading the driver from the ASUS website but I can't install it. I don't know the proper syntax. Can anyone help me out?

If lsusb says that the device is 0b05:17d2, then you need the driver 8812au. With a temporary wired ethernet connection, open a terminal and do:

sudo apt-get install linux-headers-generic build-essential

Please check here: https://github.com/abperiasamy/rtl8812AU_8821AU_linux On the right hand side, click 'Download ZIP.' Assuming downloads go to your Downloads folder, open the folder, right-click the zip file and select 'Extract Here.' Open a terminal and do:

cd ~/Downloads/rtl8812AU_8821AU_linux-master
sudo make install
sudo modprobe 8812au

It 'makes' with a couple of warnings on my 13.10 system, but no errors. I can test no further since I haven't the device. This is a rather new device and we'll be very interested in your report.

Whenever a later kernel version, also known as linux image is installed by Update Manager, after you reboot, you will need to re-compile the driver:

cd ~/Downloads/rtl8812AU_8821AU_linux-master
make clean
sudo make install
sudo modprobe 8812au

To gather further data, open a terminal and run:

lspci -nn > wifi.txt
lsusb >> wifi.txt

Find the file wifi.txt in your user directory and transfer it on a USB key or similar to a working, connected computer. Go here: http://paste.ubuntu.com/ Copy the entire text document and paste it in the text block. Click 'Paste!' A link will be created which you can then copy to post here. Here is an example: http://paste.ubuntu.com/6751980/ Then we can examine the result and advise you further.

If you are having trouble connection, please try right-clicking the Network Manager icon, select Edit Connections, select Wireless and then Wireless Security. Input the name of your network and carefully input your WPA password. http://i.stack.imgur.com/4OoHG.png

Next select IPv4 settings and, under BSSID, input the MAC address of your access point; confirm with:

sudo iwlist wlan0 scan

Please see this example. http://i.stack.imgur.com/C8Z6w.png

Now can you connect?

I notice in the manufacturer's specifications that this is specifically a USB3 device: https://www.asus.com/Networking/USBAC56/#specifications Are you attached to a USB3 connection on your computer? Check:

lsusb -vv | grep bcdUSB

I wonder if your device will operate correctly without the advanced features of USB 3.0 and whether it is backwards compatible.

Do you have a USB3 connection available?
