WUSB6300 wireless not working

Question

I've been unsuccessful getting the WUSB6300 to work on Ubuntu 19.10. I've executed the instructions at this website

My output from lsusb is "Bus 002 Device 009: ID 13b1:003f Linksys WUSB6300 802.11a/b/g/n/ac Wireless Adapter [Realtek RTL8812AU]"

My output from lsmod shows the 8812au listed. My output from lshw -C network doesn't show the WSUSB6300, 8812au, or any type of wireless adapter, only the Realtek PCI Express Gigabit Ethernet Controller that's integral to the motherboard.

What am I missing? I can't help thinking that there's something I'm not doing that would enable this dongle to be recognized and used.

Thanks in advance!

Apologies, I should clarify..this "radio button" is selectable for enable & disable. I've done both, with no difference in connection, i.e. no wireless established after either enabling or disabling

Answer 1

I had the same problem with 18.04 and Linksys WUSB6300.

These are the steps I used to get up and persist reboots:

On Ubuntu Server

Install the tools:

sudo apt install wireless-tools && sudo apt install wpasupplicant

Install the driver:

sudo apt install rtl8812au-dkms

Now open.yamlfile in netplan for editing:

sudo vi /etc/netplan/50-cloud-init.yaml

Replace wlan0 with the name of your adapter (do ifconfig to find it).

Netplan file should look similar to this:

network:
version: 2
renderer: networkd
    ethernets:
        eno1:
            addresses: []
            dhcp4: true
            optional: true
    wifis:
        wlan0:
            addresses: []
            dhcp4: true
            dhcp6: true
            access-points:
                "my_essid":
                    password: "my_password"

Now generate and debug:

sudo netplan --debug generate

Apply the configuration:

sudo netplan apply

Now remove ethernet wire and reboot:

sudo reboot

Info:
My sudo dkms status output:

rtl8812au, 4.3.8.12175.20140902+dfsg, 4.15.0-96-generic, x86_64: installed  

And your output has 2 versions of drivers installed. You must uninstall rtl8812AU_8821AU.

Note: Connection and ip established after netplan generate. Omitting optional: true for ethernets will prevent persistence upon reboots.

For Ubuntu Desktop 18.04 through 20.04:

Update the package database:

sudo apt update

Install required packages:

sudo apt install git build-essential

Download the driver:

sudo git clone https://github.com/gnab/rtl8812au

Go to the directory:

cd rtl8812au

Do the next commands consecutively:

sudo make clean
sudo make  
sudo make uninstall 
sudo make install

Reboot and insert USB wireless stick

• Persists reboots
• Works for WUSB6300
