I believe that your device uses the Qu- and Quz-series of firmware blobs, not the 9000- or 9260-series; reference: https://bugs.launchpad.net/hwe-next/+bug/1833065 at comment #4. I believe that the later linux-firmware version 1.183 contains the referenced 48.xx versions. Please install it:
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/...

With a temporary working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:
sudo apt update
sudo apt install build-essential dkms git
git clone https://github.com/cilynx/rtl88x2bu.git
cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}

Disabling WiFi power management solved this problem for me. In the file /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf, I changed it to look like this:
[connection]

Restart NetworkManager (sudo systemctl restart NetworkManager) and it should be go to go.

I've encountered this issue before, I think there are two possible solutions to it (without reinstalling the whole system that is):
Try disable "Enhanced Session" mode (ie. the xRDP mode) if you are currently using it, and login to the system with normal mode and try changing the network configuration, and see if NetworkManager will prompt you for ...

Switch from a 2G swap partition, to a 4G /swapfile, and change vm.swappiness.
Note: all of these changes can be easily reversed.
In terminal... create a new 4G /swapfile...
sudo swapoff -a
sudo rm /swapfile
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
Use the free -h or swapon ...

There is a misunderstanding about hosts file here.
First of all, hosts file have precedence over DNS on most operating systems, you can define them on Linux/Unix operating systems and macOS in /etc/hosts and c:\windows\system32\drivers\etc\hosts on Windows.
So when you add a record in your hosts file like:

and try to open http://...

Due to the way your installed the driver, your wifi driver needs to be reinstalled every time the kernel gets updated via Software Updater.
You need to follow the dkms install instructions to fix this. See README.md...

Remove available drivers with (skip if sudo lshw -C network and dkms status do not show any wifi drivers):

Turns out it was an AWS limitation. Apparently talking between EC2 instances inside the same VPC has an active connection limit of around 120,000. Making them use a public IP to communicate got rid of the limit. I wasn't getting any errors in Ubuntu because the OS was not limiting anything.

Strangely no one of the shared folders appear in the smb.conf file,
but the public folder is shared correctly.
Because you created the share from your file manager. Your samba shares will be listed in the output of this command:
net usershare info --long
In order for an smb client to access a Linux samba share 3 things are required:
