On UI screen, I was getting a dialog box saying unable to authorized and same for dmesg. It was trying for three times and it seems router was not responding back after submitting authorization credentials. I missed to collect all specific info otherwise I would have provided here for further debugging. I can't reproduce it as I have switched to Ubunut 18.04 and is working fine at the moment.

Hello, when the Laptop with Ubuntu 20.04 LTS OS tried to connect to the C60 Wi-Fi, is there any error message?
You may try to modify the wireless settings on the C60, such as wireless channel, channel width, security, then try again.

What is the model number of your TP-Link router? Is it Archer C60 also?

@hmv Using C50 AC1200 and AX10/AX1500. No issues with LM20, which is based on Ubuntu 20.04.
Mind, that Ubuntu 20 uses netplan.io and cloud-init. Maybe your network configuration is based on them.
