Ubuntu 20.04 no wifi (Broadcom)

[John Cummo]

I installed Ubuntu 20.04.
Previous version on Dell Inspiron 1525 was version 16, the wireless connection was working.
Now with the new install 20.04, I am getting the message No Wi-Fi Adapter Found?

Since you have a Broadcom wifi, you will want to check the driver in "Software & Update" and "Additional Driver" tab.
