no wireless working
Dell E5500 laptop, broadcom wireless not working but shows up in lshw -c network. I am trying to get the wireless to work. It used to work when I had 18.04 or 18.06 installed, when I installed 22.04 not wireless. Here is the output from terminal when I ran the diagnostic utility from help.ubuntu.com:
