WiFi worked during install of Ubuntu-MATE 18.04 but not after install

Question

During the install of Ubuntu-MATE 18.04, I got WiFi working and it downloaded all the things it needed to complete the update. After re-booting to the installed disk, I can't get WiFi to work. I go to place to install 3rd party drivers and see the Broadcom driver. I click it and click install. It always reverts to no 3rd party drivers and says Broadcom is not working. If I reboot after that, it isn't there. Any suggestions?

Please [edit] your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. — Pilot6, May 09 '20 at 16:24
