This article assumes that your laptop has recently had the wireless card working on Debian recently. I have a Macbook Air (7,2? ~2015) with a BCM4360 [14e4:43a0] and use the `wl` driver. This article assumes that your laptop has had the wireless card working on Debian recently.

I'm not sure why this happened, but it was when the kernel version jumped from `6.12.41` to `6.12.43` that its symptoms showed up. I had already migrated from Bookworm to Trixie and thought I had already went through a few kernel updates since then without issues.

I had already migrated from Bookworm to Trixie and thought I had went through a few kernel updates since then without issues.
Later versions such as `6.12.48` and `6.12.58` continued to get pulled and I'd try them before rebooting to `6.12.41`. With the newer versions `/sbin/iwconfig` showed no wireless network and GNOME didn't even have a Wi-Fi listing in the Settings app top top menu.

I then realized that the wl module wasn't being loaded. What was confusing was that it said it was not foud, even though I knew it was installed since it was working on other kernel versions. I saw no error when the new versions were being instaleld, either. And thus began my discovery... After realizing that the wl module wasn't being loaded I thought maybe there was a packaging issue. I was confused since it said it was not found, even though I knew it was installed since it was still working if I booted to the older installed kernel versions.

Some sources say that Debian has no generic/meta package for the kernel and its headers. I can't find any information as to the release date of these to confirm/deny that claim. I'm just glad they work! Some sources say that Debian has no generic/meta package for the kernel and its headers.

I'm just glad they work to now keep the headers installed automatically!
