@Esther_HV Please see Broadcom wireless tip which I’ve largely copied below. These are all terminal commands and should let you connect once again.

First do

sudo lshw -class network

then

lspci -vvnn | grep 14e4

to find out if there is a broadcom (BCM4311) controller. Then

sudo apt-get update
sudo apt-get install firmware-b43-installer
sudo apt-get remove bcmwl-kernel-source
sudo reboot

then issue

iwconfig

to verify. This avoids installing a proprietary device driver that may not work as well. Good luck Esther_HV
