    Monitor mode airodump-ng can not find a network

    Hi, I melvin, i French i translate this message sorry for gramatical error !

    Here I do a project on computer security and I try to demonstrate that it is easy to find a password wifi except that ...
    I am under kali linux, I have a network card type --> 03:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)
    And I can not find a wifi network when I run airodump-ng

    That's what I do
    airmon-ng start wlan0
    airodump-ng wlan0mon
    Then the search starts and I still have nothing

    Thank you, have a nice day

    Hello, I am having the same problem using the commands posted. I still can't scan any access point in both airodump-ng and aireplay-ng.
    I hope you can help me with this as well. Thank you!

    i can still connect to the internet though.
    I've searched through the internet for this problem, but it's always unsolved. I believe it's the same problem with you?

    To run a scanner like airodump-ng you do not need to put the device in monitor mode so try starting Linux then just type

    airmon-ng

    Get the designation for the device in this case we will use wlan0

    Now type airodump-ng and the device designation - again we are using wlan0 only as an example

    airodump-ng wlan0

    You should see a list of networks. Is it possible that there simply are no networks found?

    Qca9377 pcie rev31 doesn't actually seem to support monitor mode. No one with this particular card has been successful getting it to function as intended even it gives no indication of any error.

    I was able to run monitor mode in older versions of kali linux(2017 vers.) but current version doesnot support. only monitor mode was working not packet injection.

    QCA9377 monitor mode worked in Kali 2018.2

    I think it's because your wlan0 is down, you can type 'ifconfig wlan0 up' to bring wlan0 up again.
    If you cannot do monitor mode it'ss because your wireless card's chipset (basically your wireless card) doesn't support airodump monitoring.
    I use tplink wn722n version1 which has the chipset of atheros9271. This ath9271 chipset support airodump etc.
    TPLink wn722n v1, WTXUP and other brands use ath9271 chipset. You not need to worry if you don't have tplink wn722n v1, just search for other brands that use ath9271 chipset. The main problem is the chipset.

    I have the same card: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

    Running driver: ath10k_pci

    After consulting the airordump-ng pages, it seems we need the ath9k driver to run monitor mode properly? So does that mean this particular PCI card just won't work for airmon?
    I can't do that, Dave.

    In addition, Fern WIFi Cracker is unable to scan any APs, even though I'm in an apartment building with dozens of APs around me.
    I can't do that, Dave.
