My kernel version now is 5.19.0-32-generic on Ubuntu 22.04.1 LTS.

Adapter was working in 2g and 5g modes perfectly before software update.

I tried some methods as shown here for 20.04 and earlier versions. But no success. I am stuck up.

Can anyone help with tried method?

Did you install any drivers for it? They probably didn't build for the new kernel.

When the driver for new kernel version 5.19 is released, kindly notify.

I couldn't get it to work with kernel 5.19.0-32-generic either.

I was able to solve it by changing grub to the previous kernel 5.15.0-60-generic.

Step by step: Install Grub Customizer

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Open Grub Customizer Click the General Settings and select "predefined" button, then the option of 5.15.0-60-generic kernel. It is a temporary solution until someone fixes the driver.

Now you can restart your computer.

Followed this procedure and it started working fine. Thanks for this temporary solution.

It is not a good idea to freeze kernel. It is not hard to fix it with 5.19.

This also worked for me. Downgraded the kernel, wifi working again. Thanks for the tips. Scott

@Pilot6 You are right; it is a temporary solution until someone fixes the driver. I'll edit my answer.

To solve my problem i had this commands:

  1. Remove the old and problematic driver:

sudo apt purge rtl8812au-dkms

  1. Install the new one:

git clone https://github.com/morrownr/8821au-20210708.git

cd 8821au-20210708

sudo ./install-driver.sh

I have used with sucess the proposed solution defined at Unable to install USB WiFi device RTL8812AU

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
