AC-56 USB 3 Wireless Linux Driver Setup



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: 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: 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: 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.

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.

Now can you connect?

I notice in the manufacturer’s specifications that this is specifically a USB3 device: 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.
