Configuration

WiFi-card driver

The internal broadcom wifi card BCM4331 can be used with the proprietary wl or the open-source b43 kernel module. The open-source driver requires an extra firmware package to be installed.

To use the open-source driver, ensure that the wl entry is removed from boot.kernelModules and config.boot.kernelPackages.broadcom_sta from boot.extraModulePackages (typically auto generated entries in hardware-configuration.nix). After that add following line to your system config, apply it and reboot:

networking.enableB43Firmware = true;
