ASUS Vivobook Model X570UD
Realtek Wireless 8021.ac
OS: Ubuntu 18.04

I installed from a USB drive to this system. It has two drives, one SSD (256GB) for Windows and I installed Ubuntu 18.04 on the second drive (1TB Magnetic).

The system boots up fine, but it does not recognize the wireless hardware. The system settings say: No hardware adapter fine.

The wireless adapter works fine under Windows 10.

From a terminal session, if I do:

lshw -C network

I see a message that the wired adapter is working fine, but on the second block, it shows:

Network UNMATCHED
Realtek
.......

I sent to he realtek website, but I did not find any drivers. In addition, after I do the lshw command, my mouse pointer disappears.

When I do:

lspci -knn | grep Net -A3; rfkill list

I get:

03:00.0 Network Controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b822]
    Subsystem: AzureWave Device [1a3b:2950]
    kernel modules: r8822be
0: hci0: Bluetooth
    softblocked: no
    hardblock: no

Note that when I do these commands:

lshw -C network

or

lspci -knn | grep Net -A3; rfkill list

The mouse pointer disappears, and I have to power down.

Any ideas?

Try this out, I also faced the same problem a few days earlier, follow these steps:

  1. Click on the Show Applications icon on the bottom of favorite apps bar (it has an icon of dotted points).
  2. Select Software & Updates option.
  3. Go to additional drivers tab.
  4. It will show your wireless network driver, you have to select to Using [whatever name of the driver is there].
  5. Provide permission if it asks for any.

Now check if your wifi option has appeared, if not reboot the system and Voila! your wifi is working.
