Urgent: Backwards WEP Decryption?

    I setup a secured network for the office, and over the past month configured all the computers with the network key.

    Then someone decided to "fix" the internet and push the reset button on the back of the router, which apparently killed the WEP.


    I have the network key in front of me, but I forget what I used to generate it.
    I've looked on the web for a backwards decryption but couldnt find it.

    Anybody have a solution?
    Kinda urgent.

    If you have the WEP key that was generated by a paraphase key generator, all you have to do is use the WEP key and forget about the paraphase you used to generate it. Enter it in the first key field.

    yeah that definitely was a good idea.

    all four network keys are the same. is that ok?

    i guess its safer in some way.

    You can specify that all four keys are the same. The paraphase key generator generated four keys and you can specify which key to use. Just a reminder paraphase key generators from different manufacturers generate different keys for the same input.

    I see. No wonder I couldnt find a decryptor easily.

    Thank you.
