No WiFi networks listed; Ubuntu 20.04; Broadcom BCM4360

I’m not able to view any wifi networks using my BCM4360 network card in my laptop using 20.04. Could anyone help me out here? Thanks.

Please let me know if any other information is required to help debug this problem

Edit: Interestingly, ubuntu is able to list nearby bluetooth devices.
