Archer T3U not connecting in Ubuntu 20.04.1

I'm using Ubuntu Budgie 20.04.1 x86_64, kernel 5.4.0-60-generic. I'm temporarily using my phone via USB for connection. I've recently acquired an Archer T3U USB wifi adapter, which works perfectly in windows. However, I'm having issues in getting it to work in Linux. Looking around in the forums, I've found three repositories which seem to solve most people's problems:

However, none of them seem to work from me. The best I can get is for it to recognize the module and show available networks, but it doesn't succeed in connecting to any. Here are the steps I took in my latest attempt (using after trying ):

• removed previous module

sudo dkms remove rtl88x2bu/git --all
cd RTL88x2BU-Linux-Driver/
make uninstall
sudo make uninstall
sudo rm -rf ~/RTL88x2BU-Linux-Driver/
sudo rmmod 88x2bu

• add new one

git clone
sudo dkms add ./rtl88x2bu
# and after taking care to remove my phone (I've seen in one of the other askubuntu threads someone say that this helped):
sudo dkms install rtl88x2bu/5.6.1
reboot

After rebooting, after inserting the USB module it does show up in the GUI menus, but nevers finishes to connect. Some more info:

• secure boot was disabled before I started

• lsusb does show the module:

Bus 001 Device 027: ID 2357:012d TP-Link 802.11ac NIC

• rfkill is not blocking the device:

5: phy5: Wireless LAN Soft blocked: no Hard blocked: no

• sudo lshw -class network shows this (after all the other entries for ethernet, etc):

*-network:2 description: Wireless interface physical id: 3 bus info: usb@1:2 logical name: wlxd03745fee556 serial: d0:37:45:fe:e5:56 capabilities: ethernet physical wireless configuration: broadcast=yes driver=rtl88x2bu multicast=yes wireless=unassociated

Can anybody help me with this? I have no idea what to try next, and I need this USB Wifi module to function in order to use Ubuntu for work in this machine

git clone
cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

I have just used above instructions from the link listed above to install T3U on Ubuntu 20.04 LTS.

I have not any credit in solving this problem. It works for me.
