$ readlink /sys/class/net/wlan0/device/driver
../../../../bus/pci/drivers/ath5k
In altre parole, il /sys gerarchia per il dispositivo (/sys/class/net/$interface/device ) contiene un collegamento simbolico al /sys gerarchia per il conducente. Lì troverai anche un collegamento simbolico al /sys gerarchia per il modulo, se applicabile. Questo vale per la maggior parte dei dispositivi, non solo per le interfacce wireless.
Forse c'è un modo migliore, ma ho usato lshw -class network (come root) e mi dà questo output:

Puoi grep per driver da quell'uscita. Nel mio caso uso lsmod | grep iwlagn , dandomi:
iwlagn 63559 0
iwlcore 67702 1 iwlagn
mac80211 123574 2 iwlagn,iwlcore
cfg80211 87657 3 iwlagn,iwlcore,mac80211
Non chiedermi cosa significa ciascuno di questi :)
Se sei interessato ai dispositivi WiFi basati su USB, puoi vedere il nome del driver utilizzando lsusb comando:
lsusb -t
