Hey,

the wireless interface has disappeared after the recent upgrade. linux-firmware is installed. Any tips on how to troubleshoot it? Thanks.

Start by looking at the system journal and test the LTS kernel.

But before any of that compare "uname -a" and "pacman -Qs kernel".
Chances are you either didn't reboot after a kernel update or are booting a older kernel because you forgot to mount the boot partition or are booting from the root partition (if unsure, see whether "cat /proc/cmdline" references the kernel by /boot/vmlinuz* - in that case you're booting from the root partition) and the general consequence is that there's no wifi module for your running kernel.

I have recalled that the driver I have been using was wl. When I do modprobe wl I get:

modprobe: FATAL: Module wl not found in directory /lib/modules/6.7.7-arch1-1

kernel and broadcom are at 6.7.8

Yes it works after upgrade, thanks Perhaps I have upgraded at the wrong time where the broadcom-wl package was made for the newer kernel before the newer kernel got in the repo.
