I'm not seeing the WiFi icon on laptop. I've started facing this issue recently after some update that happened. I'm not able to connect to network as well.

It sounds to me like the driver may be missing for the wireless card.
You could try checking "Software & Updates" in your menu - then look in the "Additional Drivers" tab.
If nothing is there, then I recommend researching to see where you can get the drivers, starting with:
- Manufacturer's website - they may provide a Linux driver - or even an Ubuntu-specific driver
- Figure out what network card you have (eg. from Manufacturer's website) and search for Linux/Ubuntu drivers for that card
Edit: It could also be an issue with Network Manager - you could try re-installing that.
