BCM4312需要另外安装broadcom驱动

emerge -av broadcom-sta

Wireless-N 7260 需要安装ucode

iwl7260-ucode

安装iw, libnl

emerge -pv iw libnlCalculating dependencies... done![ebuild   R    ] dev-libs/libnl-3.2.27:3::gentoo  USE="-python -static-libs -utils" ABI_X86="(64) -32 (-x32)" PYTHON_TARGETS="python2_7 python3_4 -python3_3" 0 KiB[ebuild   R    ] net-wireless/iw-4.3::gentoo  0 KiB

安装wpa_supplicant，deconfig配置

CONFIG_DRIVER_NL80211=y
