WEP passphrase not working

    I'm currently using Tomato 1.23 and it's been very stable. I've always used WPA for my wireless connection, but since I got a Nintendo DS Lite I need to configure it to WEP.

    The only problem I'm having is that Windows XP and the DS Lite aren't accepting the passphrase I'm stipulating. Is this a known bug or am I configuring something wrong?

    If I use the hexadecimal key, there's no problem. Using the hexadecimal key isn't feasible because I need a easy to remember passphrase for the other users of my connection.

    I suppose there are some rules for the passphrase. All the ones I ever used have been relatively small, alphabet only, under 8 letters, and they've all worked OK, if that helps you at all.

    i suggest in this format, something like

    bad<your-phone-number>cab

    form a simple word using A-F, then followed by an easy to remember number like a phone no.

    My experience is that hexadecimal keys are the only thing that work reliably with WEP. There doesn't seem to be complete agreement among vendors on how to convert pass phrases into the internal 40-bit or 104-bit hex password. I've encountered problems when switching OSes, switching routers, and the like.

    You're comfortable with the idea that WEP is completely broken and won't offer you any security against a determined hacker?

    There's no choice since the DS Lite uses WEP.

    Are we talking about the "passphrase" (used for generating wep access codes by many routers) or the WEP key itself? Any "passphrase" used in tomato generates 4 hex keys and you choose which one you wish to use. I just tried manually inputting an alphanumeric key into tomato, and also one with no numbers, and they all worked OK with 64 bit WEP access. So you should be able to cobble something together that will work on both.

    Of course you have choices.
    • You could return the DS Lite saying you refuse to use any product that doesn't take your security seriously. (Does the packaging indicate that it only supports WEP?)
    • You can isolate the DS Lite on its own wireless router. You probably don't care if a hacker cracks the communication between your Nintendo and the 'net.
