    Default Failure to authenticate

    Hello,

    While trying to learn about wireless security, I made a airodump-ng ath0 and here's my output :

    BSSID PWR RXQ Beacons #Data, #/s CH MB ENC CIPHER AUTH ESSID

    00:00:C5:C4:8E:39 20 13 238 596 0 6 11 WEP WEP 61107375
    00:14:7F:CD:BB:47 18 100 1560 35 0 6 48 WEP WEP portablebernardw
    00:13:F7:31:0D:91 18 100 2213 14 0 6 54. WEP WEP SMC

    I'm testing ESSID SMC ( as finding the WEP for the first 2 networks went like a breeze ) but when I go through authentication, here's the output :

    23:33:11 Waiting for beacon frame (BSSID: 00:13:F7:31:0D:91)

    23:33:12 Sending Authentication Request (Open System)

    23:33:14 Sending Authentication Request (Open System)

    etc etc ...

    until it writes :
    Attack was unsuccessful.

    I have a power of 18 ( PWR column ) , could it be that the signal is too weak ?

    Strangely, in the shell window showing the airodump, it shows that I'm linked to the network for around 1 minute ... what could be the reason ?

    How would you try to authenticate ? What kind of attack would you try to perform ? ( if it's not a problem of a weak signal ? )

    Cheers

    Were the first 2 your neighbors networks and the last one yours? Cause if the last one was yours..that would be ironic. (Crack theirs, but not yours..lol)

    Well, I finally managed to have it worked.

    Strangely, it seems like I can authenticate myself successfully the first time, but then, if I take too much time before launching an attack, it gives the messages described before.

    Is it a known behaviour from an AP ? Do you think a tutorial could be made on all the various ways to get authenticated with an AP ? ( so even before launching any attacks )

    Cheers
