Using reaver (for wifi hacking) on Ubuntu 20 issue

I am trying to find out(to hack) my wifi password, just for fun and learn something new :) . I followed the tutorial:

And this is how far I got:

1. This is the result of my iwconfig:

   lo no wireless extensions.

   wlp2s0 IEEE 802.11 ESSID:"TP-Link"
   Mode:Managed Frequency:5.2 GHz Access Point: D8:07:B6:86:86:1F
   Bit Rate=6 Mb/s Tx-Power=23 dBm
   Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=70/70 Signal level=-40 dBm
   Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:62 Missed beacon:0

2. After I run:

   sudo airmon-ng start wlp2s0 and I got this:

   Found 4 processes that could cause trouble. Kill them using 'airmon-ng check kill' before putting the card in monitor mode, they will interfere by changing channels and sometimes putting the interface back in managed mode

    PID Name
    765 avahi-daemon
    774 NetworkManager
    806 wpa_supplicant
    810 avahi-daemon
   

   PHY Interface Driver Chipset

   phy0 wlp2s0 ath10k_pci Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

        (mac80211 monitor mode vif enabled for [phy0]wlp2s0 on [phy0]wlp2s0mon)
        (mac80211 station mode vif disabled for [phy0]wlp2s0)
   

3. After I killed all of the processes with:

   sudo airmon-ng check kill

4. And finally I run: sudo airodump-ng wlp2s0mon to get the list of wifi networks and I got this:

My expectations would be to get some BSSID s.

The final step would be to run reaver -i wlp2s0mon -b {BSSID value}. Would you please let me know what I did wrong or what should I do next, so I can continue my study? Thank you

Solution 1:

1. It is possible that your wifi adapter does not support monitor mode, if he is, those commands should work out.
   • for monitor mode (run with sudo or as root):

ip link set wlp2s0 down
systemctl stop wpa_supplicant.service
systemctl mask wpa_supplicant.service
iw dev wlp2s0 set type monitor

2. now you can run your airodump commands, for a test run:

airodump-ng wlp2s0

3. to get your wifi interface back to managed mode you can run this commands (run with sudo or as root):

ip link set wlp2s0 down
systemctl umask wpa_supplicant.service
systemctl start wpa_supplicant.service
iw dev wlp2s0 set type managed
ip link set wlp2s0 up
systemctl restart NetworkManager.service #only if wifi connection does not came back alone.

I build those two scripts to switch between monitor and manage mode:

• managed.sh

#!/bin/bash

#Run As Root

echo "please enter a interface: "

read interface

ip link set dev $interface down

systemctl stop wpa_supplicant.service

systemctl unmask wpa_supplicant.service

systemctl start wpa_supplicant.service

iw dev $interface set type managed

ip link set dev $interface up

• monitor.sh

#!/bin/bash

#Run As Root

echo "please enter a interface: "

read interface

ip link set dev $interface down

systemctl stop wpa_supplicant.service

systemctl mask wpa_supplicant.service

iw dev $interface set type monitor
