    One WEP key can be shared by multiple clients or each client should have unique key?

    If can be shared, why there are 4 keys?

    I believe you can set restrictions to WEP keys just like you can to MAC addy's. Thats why you can enter 4 different Keys. ( lets say you owned a Cafe' and you used the same router for your customers that you use. after the shop closes you want to be able to still use the internet but not anyone that you gave the WEP too for the shop )

    Only the first WEP key is used not the second, third or fourth. The paraphase key generator produces up to four keys.

    Actually you are all mistaken. Only a single WEP key can be active at any one time.

    The reason you have space for up to 4 WEP keys is so you can generate, store, and distribute 4 of them. You will always notice a box that says "active key number" letting you select 1 to 4. The original idea was something like this:

    1) Generate 4 keys
    2) Set all 4 keys into the AP
    3) Set AP to use Key#1
    4) Distribute all 4 keys to clients, set into client software
    5) Set clients to use Key#1

    Then when a week had passed or you were worried your 1st key might have been cracked, you could do this:

    1) Change AP to use Key#2
    2) Tell users to switch to Key#2

    My WRT54G nor my WRT54GX allow me to set the second, third or fourth key. The clients can be set to use the other keys. I would not use WEP anyway. Use WPA or WPA2 if your equipment allows it.
