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 make 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 make 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.
