# :check mark button: Wi-Fi Setup Guide for Debian 12.11 on a 2010 Mac ## :magnifying glass tilted left: Step 1: Identify Your Wi-Fi Chipset Open a terminal and run: ``` lspci -nnk | grep -iA3 network ``` Look for lines like: ``` 03:00.0 Network controller: Broadcom Inc. BCM4322 [14e4:432b] (rev 01) Subsystem: Apple Inc. AirPort Extreme Kernel driver in use: b43-pci-bridge Kernel modules: b43, wl ``` ## :brain: Step 2: Determine Firmware Needed | Chipset | Firmware Package | | ------- | ---------------- | | BCM43xx (most common) | `firmware-b43-installer` | | BCM4312 rev 01 | `b43-fwcutter` + `firmware-b43-installer` | | BCM43xx rev 03 or 04 | `broadcom-sta-dkms` instead | ## :hammer and wrench: Step 3: Install Firmware Basic install (most Broadcom chips): ``` sudo apt update sudo apt install firmware-b43-installer ``` Or install all common firmware packages: ``` sudo apt install firmware-linux firmware-linux-nonfree firmware-misc-nonfree firmware-realtek firmware-b43-installer ``` ## :counterclockwise arrows button: Step 4: Reboot and Load Wi-Fi ``` sudo reboot ``` Then test: ``` iwconfig nmcli device wifi list ``` ## :warning: Step 5: Manually Load Driver (If Needed) If Wi-Fi still doesn't show up: ``` sudo modprobe b43 ``` To make it permanent: ``` echo b43 | sudo tee -a /etc/modules ``` ## :check mark button: Step 6: Install GUI Wi-Fi Tool (Optional) If you're using XFCE or LXQt: ``` sudo apt install network-manager network-manager-gnome nm-connection-editor ``` ## :light bulb: Tip: If you're unsure about your chipset, paste the output of: ``` lspci -nnk | grep -iA3 network ``` And we can tell you exactly which driver to install.
