La carte wifi est donc:Device-1: Qualcomm Atheros AR928X Wireless Network Adapter
vendor: AzureWave AW-NE771 802.11bgn driver: ath9k v: kernel port: 18e0 bus ID: 05:00.0
chip ID: 168c:002a
IF: wlp5s0 state: down mac: <filter>
Et dans /etc je trouve:
file:///etc/modprobe.d/blacklist-ath_pci.conf
For some Atheros 5K RF MACs, the madwifi driver loads buts fails to
# correctly initialize the hardware, leaving it in a state from
# which ath5k cannot recover. To prevent this condition, stop
# madwifi from loading by default. Use Jockey to select one driver
# or the other. (Ubuntu: #315056, #323830)
