Hi and welcome to the forum.

Have you tried installing drivers for your hardware?
Also seen one item that asks if (BIOS) "Secure Boot" is disabled.

My websearch using "Broadcom BCM43142 unclaimed Ubuntu 20.04" found this:
(Note Z16.x is based on Ubuntu 20.04)

See this: wireless - BCM43142 WiFi adapter doesn't work on Ubuntu 20.04 - Ask Ubuntu

Also may be of help:
networking - How do I fix network UNCLAIMED wifi failure? - Ask Ubuntu.
