Just notices that I have no option for Wifi in the NetworkManager widget in the taskbar in kernel 6.1.1-1
Using kernel 5.15.85-1 works as normal though.
The troubleshooting section here may be of some help. If you have broadcom-wl installed you will need to reinstall it. If you have broadcom-wl-dkms installed it should have updated when you updated the kernel.
