Public bug reported:
During installation of Xubuntu 26.04 on a MacBook Air 6,2 (Early 2014) with a
Broadcom BCM4360 wireless adapter (PCI ID: 14e4:43a0), the installer option
"Install third-party software for graphics and Wi-Fi hardware" does not result
in working Wi-Fi after installation.
The installer appears to attempt installing bcmwl-kernel-source, which fails to
compile against kernel 7.0.0-22-generic with no visible error to the user.
The correct package for this hardware and kernel combination is
broadcom-sta-dkms (6.30.223.271-29ubuntu1), which compiles successfully and
provides full Wi-Fi functionality including 802.11ac at 866.5 MBit/s on 5GHz.
Steps to reproduce:
1. Install Xubuntu 26.04 on hardware with BCM4360 (14e4:43a0)
2. Enable "Install third-party software" during installation
3. After installation, Wi-Fi does not work
Expected result:
Wi-Fi works after installation
Actual result:
Wi-Fi does not work. Manual fix required:
sudo apt install broadcom-sta-dkms
Hardware:
- MacBook Air 6,2 (Early 2014)
- Broadcom BCM4360 802.11ac (PCI ID: 14e4:43a0, rev 03)
- Kernel: 7.0.0-22-generic
