sudo apt install firmware-*
不知道硬件对应哪个驱动，索性全部安装。如果遇上几个包冲突，不安装也不一定不行，比如这般：
sudo apt install firmware-iwlwifi firmware-realtek firmware-ivtv firmware-ralink firmware-ti-connectivity firmware-amd-graphics firmware-myricom firmware-ath9k-htc firmware-samsung firmware-atheros firmware-libertas firmware-netxen firmware-linux-free firmware-intelwimax firmware-linux-nonfree firmware-brcm80211 firmware-intel-sound firmware-cavium firmware-b43legacy-installer firmware-qlogic firmware-adi firmware-zd1211 firmware-misc-nonfree firmware-netronome firmware-b43-installer firmware-bnx2x firmware-ath9k-htc-dbgsym firmware-qcom-soc firmware-linux firmware-bnx2 firmware-microbit-micropython-doc firmware-ipw2x00 firmware-siano
