I start airodump-ng, beacons keep increasing, but as soon as I associate successfully with fakeauth attack, beacons stop. After a while networks disappear from airodump, and running it again shows no networks. Any ideas?? Hello, I’d really appreciate if you helped me out here :)

See method #2 where I discuss fake authentication and de-authentication. Yes, WEP can still be broken on an AP even if clients have never been or are currently not connected.

This is about a wireless named: WLAN_XX, Itried the same in 3 differents wlans WLAN_XX and the same result. I have not yet tried to change the MAC, but theoretically if MAC filtering where active the AP should reject my packets Does someone knows what's going on? Tnks Hi there,
i need your help becase i would understand a strange case:
0) AP seems to accepts any key of 10 legnth
1) I cracked a web key and i got the key (using air..mon..dump…reply..crack )
2) i tried dhcp and nothing
3) i fixed IP used by default by this vendor and mac 255.0.0.0 and nothing neither with 192.168.0.1
4) I made ping scanning for determining router IP and nothing. i did for all IP internal addresses and changing ip when needed!!!!

This is about a wireless named: WLAN_XX, Itried the same in 3 differents wlans WLAN_XX and the same result.

I have not yet tried to change the MAC, but theoretically if MAC filtering where active the AP should reject my packets

Does someone knows what’s going on?

Tnks

I'm confused with -h option. Is this my card mac address or any connected client mac address obtained with Kismet? Other questions is about interactive attack in the fist method. Sould the packet contain the AP mac address as destination and the connected client (obtained with Kismet) as source? Thanks. Good job!

I am trying to crack a wep from an AP that recently had a client. I was able to gather a packet from the client before it went offline. I am sending the packet and in my airodump window I see the packet number going up but the data number is going up very very slowly. I have tried a fakeauth attack and it says sending authentication request about 5 or 6 times and comes back and says there is a problem. I have tried doing a arpreplay with aireplay and I can see the packets again going up, most of them are noted as being lost, and it says that I am receiving arp requests, yet again very slowly going up as well as the data. I have been doing this for over two hours, and I notice that in my aircrack window it says its tried over 2 million keys and has got like 11,000 IVs. Am i doing something wrong, or does the AP have a mac filter or blocking some other type of requests? Thanks for the help Cam I cannot seem to be able to generate enough IVs.

I used method one, but couldn't find an appropriate packet; method two worked in about ten whole minutes. Only oddity was that iwconfig wanted my adapter UP (not down) before it would put it into monitor mode. Seemed strange to me, but maybe this was because it had already associated itself with another network? Anyway, awesome, it works, etc. Worked for me w/my linksys WUSB54GC.
