Ubuntu 20.04 Wifi not connecting automatically

I have installed Ubuntu 20.04 on a new PC and using wifi dongle (https://www.amazon.in/Live-Tech-Nano-Wirless-Adapter/dp/B078SSXTG7) to connect to wifi. I have saved the passwords, but every time on starting Ubuntu, I have to manually connect to the wifi network and provide password. It does not automatically connect. Moreover, when I got to wifi setting under visible networks I see several duplicate entries for my wifi – one for each time I have given the password. Can someone please help me in this. If any more information is needed, please let me know.

>Solution :

Automatically connecting to wi-fi through built-in method is still not working for some reason. I have found an alternative way to connect to wifi at startup(with a known BSSID as mentioned by @mchid above).

To get BSSID for your wifi please refer below question.

Getting BSSID and connecting to it is referred to from here.

nmcli -f in-use,ssid,bssid,signal,bars  dev wifi

Once you get the BSSID from above create a shell script connect.sh with below text

#!/bin/bash
nmcli d wifi connect xx:xx:xx:xx:xx:xx password "yourpassword"

replace xx:xx:xx:xx:xx:xx with your BSSID.
save the file and change the file permission to make it executable

chmod +x connect.sh

In Ubuntu 20.04 there is an application "startup applications" that can be accessed from the GUI. add the above script file in startup application and now it connects automatically on startup.
