    Default Two airdrop-ng problems.

    Hello,

    I am having two problems configuring airdrop-ng.

    I am using an Atheros AR928X chipset on wlan0.

    Here are the commands that I issued:

    airmon-ng start wlan0
    airodump-ng mon0 -w filename --output-format csv
    airdrop-ng -b -l -i mon0 -t filename-01.csv -r rules.conf

    Problem I:

    Error Message from lorcon:
    Failed to set channel 143 22:Invalid argument
    Unable to set channel card does not seem to support it
    Skipping packet

    I checked the output from airodump-ng and sure enough there were various strange channels such as 143, 158, -1, and suchlike.

    So I tried to set the channels in airodump-ng using:

    airodump-ng -c 11
    airodump-ng --channel 11
    airodump-ng -c 1-11
    airodump-ng --channel 1-11
    airodump-ng --channels 1-11

    Nothing worked - I still received strange channels.

    So I tried:

    airmon-ng start wlan0 11
    airmon-ng start wlan0 1-11

    Nothing worked.

    And so I tried a combination of using channels with both.

    Nothing worked.

    Question I:

    How can I set the channels in airodump-ng?

    Problem II:

    Another error message was:

    Error Message from lorcon:
    Failed to set channel 8 16evice or resource busy
    Unable to set channel card does not seem to support it
    Skipping packet

    Obviously channel 8 does exist.

    Question II:

    How can I correct this error?

    Many thanks!

    Default Re: Two airdrop-ng problems.

    Answer I:
    To set the channel in airodump-ng you have to add -c. For example: "airdrop-ng -c 11 wlan0"

    Answer II:
    To run airodunp-ng you have to:
    airmon-ng stop wlan0
    airmon-ng start wlan0
    airodump-ng mon0

    To fix the resource busy problem you have to run "airmon-ng stop mon0", then "airmon-ng stop wlan0"
    (stopping mon0 is necessary, but I do anyway.)


    I hope this fixes it. If not, just let me know.
