Dell Latitude E5500 with Broadcom Wi-Fi adapter was working fine with OS17. I upgraded to 18 today and upon first boot there was a message on the lower part of the screen after logging in saying additional drivers were available. What is happening is it looks like Wi-Fi is working, but it does not see any networks. Even my saved Network will not show or connect. I have Ethernet plugged in and this is not a mission critical laptop so I am open to suggestions and trying things out. It currently is showing "Using dkms source for the Broadcom STA Wireless driver from brodcom-sta-dk" and it is checked. The adapter is a Broadcom 14e4:4315
You could try booting with an older kernel (in the GRUB menu, select "Advanced options for Zorin" and select an older kernel).
Welcome to the Forum!
Could You post the Output of the Command sudo lshw -C network please? Also: Could You post a Screenshot from the Additional Drivers Tab, too?
Thanks! Here is the output.

Thanks, booting from 6.8.0-107-generic does work and Wi-Fi connects to my AP.
