    Im using WRT54G with v3.03.9 firmware, on the client side im using the wmp54G with driver version

    Since I was having problems with WPA ( just kept disconnecting ), I switched over to 128 bit WEP in deep frustration. Now heres the funny thing...

    I set the passphrase in the router to : ihoivburvbtiwepo
    and when setting the password on the client, i accidently set it to something completely different.

    ...and the client STILL connected to the router. Checking into it further, it seems the ruter accepts any connections using WEP ( any passphrase ). Can this be an issue that some credentials are cached on my computer, or is this a serious bug in the ruter firmware?

    maybe you should try a computer to connect to the router using wep. anbd see if you can connect now

    I you mean I should test it with another computer, I cant. I have only this one with wireless capabilities. But I dont see how it can be cause of cached credentials.... because when I change the passphrase on the router, whatever I had cached on my computer should be null and void.

    But it looks like the router accepts any passphrase I use on the client.

    Can anyone else confirm the same problem?
