    Default so i have cracked a wep key and it doesn't work? help?

    Basically I'm a computer science student and I've got an assignment to do on wireless cracking, I've set up a password proteccted wep AP.
    I've snorted way over 30,000k packets and put them into a file called wep01.cap.
    I've used:
    root@root:~# aircrack-ng wep01.cap
    and it's given me the key in hex, so I've tried to use the key it's given me as the wep key for the AP and it's telling me it's a bad password. I'm lost as to what to do, any help would be very highly appreciated.
    Manfree.

    Nooo, it should look like something similar to this XX:XX:XX:XX:XX (If its an standard 64bit KEY) 128 is double that,

    you will need to remove the :::::::::: From the key, but it should work as you see it after removing the :'s just throw that into a wireless connection manager, good to go

    If you've cracked it and received the hex code, remove the colons (" : ") so you're left with just the 0-9 A-F hex numbers/letters. When you login to the network make sure you tell it you're typing the password in HEX.

    You set up the AP didnt you? Are you unable to compare the key you found with the one you gave the AP? If that's not so then this isn't your AP. Surely a comp science major can do this.

    Are you sure you cracked the WEP code for that SSID and not another? You know if you don't specify what to crack in aircrack it will crack anything you scanned, maybe the result if of another network?

    Do you have the actual WEP code you're trying to crack to compare?

    Tip: Maybe there are other SSID with the same name. Make sure that it is the correct mac address of the router.

    Make sure you're close enough to the router. This may sound too simple but I went through the same thing a few weeks back.

    if your trying to logon with backtrack and uing wcid then make sure the option for entering the key is hex. alternatively use a windows laptop and logon for trouble shooting

    If you specify "#airodump-ng --bssid APMAC -c 11 -w wep01 wlan0"

    channel 11 for example and APMAC is the Mac address of the AP you will save on the pcap file only the packets captured from the network you want to get in.

    So when you try later on "#aircrack-ng --bssid APMAC wep01*.cap"

    You shouldn't get any problems at all. Perhaps it would help if you describe what steps have you made during your attack. Good luck with that.
