MacBook の Boot Camp の Ubuntu 22.04 LTS で Wifi 接続

状況

MacBook の Boot Camp にインストールした Ubuntu 22.04 LTS をいろいろアップデートしていたら(or クリーンインストールしたら)、Wi-Fi 接続ができなくなった。Ethernet による有線 LAN 接続は機能している。

対処

sudo apt purge bcmwl-kernel-source
sudo apt update
sudo update-pciids
sudo apt install firmware-b43-installer
sudo reboot

具体的な環境にもよるのだろうけど。今回はとりあえずこれだけで大丈夫だった。
本当なら lspci コマンドでネットワークアダプタを調べるなりすべきかも。
