    Default How long should collecting 1 million IV's take?

    I am trying to crack my WEP key at home. I am using a Linksys WPC11 card with Back Track 2. I sat the laptop in the same room as the wireless router and it took 2 hours just to get 2000 IV's! Is this normal or am I doing something wrong? My key is 128 bit. Thanks

    When you SEARCHED the forum before you started this topic, what terms did you SEARCH for?
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

    Is it normal, No. Am I doing something wrong, yes. key length makes little difference. Why do want to collect 1 million? provide some proper information like commands, router, hardware, What software are you using and what version. and we may be able to help. Oh and next time try formatting your question in a way that's easier to read.

    Streaker - I tried searching for how many ivs to crack wep and several other similar search criteria. I also looked through most of the tutorial area and could find nothing that would help.

    I have a Linksys router WRT54GL running DD-WRT. The card I am using is a Linksys WPC11 and I am using BT2. Here are the commands that I used:

    I ran these commands in order in seperate terminal sessions:


    airodump-ng -w capture -c 6 eth1

    aireplay-ng --arpreplay -b macaddressofap -h macaddressofclient eth1

    aireplay-ng -e ssidofnetwork -a macaddressofap -c macaddressofclient --deauth 10 eth1

    aircrack-ng -f 4 macaddressofap -n 128 capture-01.cap

    This all worked with no errors but like I said it took over 2 hours to get 2000 IV's. For the arp replay it did show arps being received and sent. Any help on this would be great. Thanks.

    Lets put it a different way. How many IV's are needed, generally, to crack a 128 bit WEP key and how long does it usually take?

    Doing it the correct way, it should take about 3 minutes.

    But there are methods that can easily reduce that to under a minute.

    I was including booting up the computer and cracking open a beer.
