如何找出安裝了哪個 Wi-Fi 驅動程序？

我知道lsmod，但我如何確定哪個驅動程序在做什麼？

$ readlink /sys/class/net/wlan0/device/driver
../../../../bus/pci/drivers/ath5k

換句話說，/sys設備的層次結構 ( /sys/class/net/$interface/device) 包含指向/sys驅動程序層次結構的符號連結。如果適用，您還可以在那裡找到指向/sys模組層次結構的符號連結。這適用於大多數設備，而不僅僅是無線介面。

也許有更好的方法，但我用過lshw -class network（作為 root）它給了我這個輸出：

driver您可以從該輸出中 grep for 。就我而言，我使用lsmod | grep iwlagn，給我：

iwlagn                 63559  0 
iwlcore                67702  1 iwlagn
mac80211              123574  2 iwlagn,iwlcore
cfg80211               87657  3 iwlagn,iwlcore,mac80211

不要問我這些是什麼意思:)
