After a fresh install of Ubuntu 20.04

The WiFi option is not available in the desktop environment Settings -> Network panel. I only see Ethernet.

This driver was working on Ubuntu 19.04, but not on 20.04

After installing the driver and re-starting there is still no WiFi options nor icons.

Also, tried a few various other flavors of the drivers like

https://github.com/aircrack-ng/rtl8812au

Currently installed via:

sudo apt install rtl8812au-dkms

Then did a reboot. Still no WiFi.

~$ dkms status
rtl8812au, 4.3.8.12175.20140902+dfsg, 5.4.0-26-generic, x86_64: installed

~$ lsmod | grep realtek

This shows the USB WiFi device.

~$ lsusb | grep Realtek
Bus 007 Device 002: ID 0bda:b812 Realtek Semiconductor Corp. 802.11ac NIC

Shows the Ethernet adapter:

~$ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether d0:50:99:7a:52:94 brd ff:ff:ff:ff:ff:ff

~$ nmcli device status
DEVICE  TYPE      STATE      CONNECTION         
enp4s0  ethernet  connected  Wired connection 1 
lo      loopback  unmanaged  --

Is there anything specific that one should try to get this to work?

Thanks

Gary

  • Any errors in dmesg/syslog? – ThankYee Apr 24 '20 at 00:39

  • try grep -i rtl - you probably only want to see what that driver is outputting? – ThankYee Apr 24 '20 at 01:05
  • $ cat /var/log/syslog | grep -i rtl

    $ dmesg | grep -i rtl

    Returns nothing.

    The correct driver for your device is not rtl8812au. It is 88x2bu. I am voting to close as a duplicate. Welcome to Ask Ubuntu. – chili555 Apr 24 '20 at 01:14
  • I would like to know who you know that?

    This is the device: https://www.amazon.com/gp/product/B07FGX8LBF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

    Linux docs point to: https://github.com/abperiasamy/rtl8812AU_8821AU_linux

    I am certain that these worked on Ubuntu 19.

    Just installed the rtl88x2bu drivers ran a reboot and it is still the same issue.

    $ dkms status
rtl88x2bu, 5.3.1, 5.4.0-26-generic, x86_64: installed

  • You can go through the source of the driver - I think usb_intf.c or something, and the driver matches the usb Manufacturer and device ID. In your case, it's 0bda:b812. Maybe it worked on 1910 because you had a different driver installed as well – ThankYee Apr 24 '20 at 03:27
